what are the two main areas of physical science

Answers

Answer 1
The two main categories of physical science is physics and chemistry. Almost all other forms of science rely on these types, and are therefore classified under these.
Answer 2

Physics and chemistry are the two major branches of physical science. Both types of physical science are concerned with the investigation of matter.

What is physical science?

In juxtaposition to life science, physical science is a branch of natural science that studies non-living systems.

It, in turn, has many branches, each referred to as a "physical science," which are referred to collectively as the "physical sciences."

Physical sciences are academic bodies of knowledge that seek to discover the underlying laws of nature, which are frequently written in mathematics.

It refers to a group of disciplines that includes astronomy, chemistry, materials science, and physics.

Aside from intellectual development, physical science fosters reasoning ability and logical reasoning in individuals.

Thus, physical science is divided into several categories, including physics, astronomy, and chemistry. Physical science can be applied in a variety of careers.

a seismograph located near the San Andreas fault detects two earthquakes. One earthquake is very strong, the other is relatively weak. How will the seismographs produced during the two earthquakes compare?

Answers

During an earthquake or any ground movement, a seismograph would produce an output called seismogram in which we could see the recording of the motion of the ground in the three Cartesian axes (x, y, and z). A seismograph has a special device called seismometer that is extremely sensitive to up and down motions of the earth and this device can be understood by visualizing a weight hanging on a spring.

Since two earthquakes are producing different relative strength, therefore the correct answer to this would be:

“The seismograms produced during the two earthquakes will be very different. The stronger one will have a larger amplitude than the weaker one.”

Final answer:

A seismograph near the San Andreas fault will record larger deflections on the seismogram for a strong earthquake and smaller deflections for a weaker one, due to the higher amplitude of seismic waves. The Richter scale being logarithmic means significant differences in energy release between different magnitudes. Additionally, three-component seismographs enhance earthquake analysis by measuring three-dimensional motion.

Explanation:

A seismograph near the San Andreas fault that detects earthquakes of varying strengths would produce different seismograms for a very strong earthquake and a relatively weak one. The seismograph's recordings, known as seismograms, reflect the earthquake strength through the amplitude of the waves recorded. For a stronger earthquake, the seismic waves will have a greater amplitude, resulting in larger deflections on the seismogram, whereas a weaker earthquake will produce smaller deflections. Additionally, the patterns of P-waves (primary waves) and S-waves (secondary waves) captured by the seismograms are crucial for determining the epicenter of an earthquake by comparing arrival times recorded by multiple seismographs.

Since the Richter scale is logarithmic, the difference in magnitude between two earthquakes is significant, with each whole number increase on the scale representing a tenfold increase in amplitude of the seismic waves and roughly a thirtyfold increase in the released energy. The seismogram produced during a very strong earthquake would show considerably higher amplitudes and longer durations than the seismogram of a weaker earthquake.

Moreover, advanced seismograph stations with three-component seismographs can provide detailed information about the earthquake source by measuring motion in three perpendicular directions (east-west, north-south, and up-down), thereby contributing to a more comprehensive understanding of the earthquake's characteristics.

Which is not a process involved in the formation of sedimentary rock?
a:weathering
b:compaction
c:deposition
d:extrusion

Answers

Extrusion is NOT a process involved in the formation of sedimentary rock.

Answer:

d:extrusion

Explanation:

Extrusion has nothing to do with the formation of sedimentary rock, since it is a process of building objects with a defined and fixed cross section. The material is extracted using a die with the cross section to be made. This process allows the creation of complex cross sections with brittle materials, since the material only finds compression and cutting forces.

explain how the metric system is based on a system of tens

Answers

Every metric unit is based of tens such as centimeters there's 100 cm in one meter. Meter is the base line and the other measure meets are bigger or smaller by powers of ten. A centimeter is 100 times smaller than one meter

Final answer:

The metric system is based on a decimal system with fundamental units meter, kilogram, and second, allowing for easy conversions using powers of ten and consistent measurements for objects of all sizes.

Explanation:

The metric system is structured on a base-10 or decimal system, where each unit is a power of ten of the fundamental units for length, mass, and time, which are meter (m), kilogram (kg), and second (s), respectively. In this system, converting between units is as simple as moving the decimal point to the right or left. For example, 1 meter equals 100 centimeters and 1 kilogram equals 1000 grams, illustrating the system's reliance on multiples of ten.

Moreover, the metric system incorporates a set of prefixes to indicate multiples and submultiples based on factors of 10, such as kilo- (1000), centi- (1/100), and milli- (1/1000). This versatility allows easy conversions and ensures consistent measurements for objects of varying sizes, from very small (like a cell) to very large (like a planet).

Compare and contrast the differences in a persons cardiovascular fitness between an exercise program that utalizes the progression principle and one that does not.

Answers

People who utilizes the progression principle will ensure their exercise program increases in frequency, intensity, time, and type. The changes need to happen gradually in order to ensure they make gains in their fitness program. A person who doesn't utilize the progression principle can still gain health benefits from exercising, but will not continue to improve in cardiovascular fitness.

Progression is the classic increase in the fitness of the individual which is essential to achieve fitness goal.

Further Explanation:

Respiratory and circulatory system works together as a coupled unit for delivering oxygen and nutrients to the other part of the body and take away carbon dioxide and waste from the body to support homeostasis. The main purpose of the cardiovascular system is to support the adequate blood flow and supply adequate amount of nutrient to all body tissue and cells and also help in regulating the body temperature.

During physical exercise, the oxygen demand of the muscle tissue increase by 15 to 25 time than normal or rest condition because the more energy is required. A hormone also helps in controlling a number of physiological reactions such as energy formation, reproductive processes, tissue growth and degradation of the muscle protein.

Progression is the classic increase in the fitness of the individual which is essential to achieve fitness goal. When an athlete starts its practice by running in the morning he complete the round in few min. but with each day and session he is able to cover more around in shorter time because he starts to overload himself with each session which is necessary to develop physical fitness.

it is because an object in motion maintains its steady motion(law of inertia).the presence of an unblanced fource change the velocity of object
Final answer:

To maintain the constant velocity of a 2-kg object moving horizontally at 4 m/s, no net force is required as per Newton's first law of motion.

Explanation:

The question asks how much net force is required to keep a 2-kg object moving horizontally at a constant speed of 4 m/s. In physics, especially when discussing Newton's laws of motion, if an object is moving at a constant velocity, the net force acting on it is zero. According to Newton's first law of motion (also known as the law of inertia), an object will continue to move at its current velocity unless acted upon by a net external force. Therefore, if the 2-kg object is moving horizontally at a steady speed and is not accelerating, the net force required to maintain that steady motion is 0 Newtons.

3. A 92 kg Tarzan is holding on to a level 22m vine. He swings on the vine. What will his speed at the bottom of the swing be?

Please help A.S.A.P.!!!!!

Answers

Final answer:

Tarzan's speed at the bottom of the swing can be found using the conservation of energy principle, resulting in approximately 20.76 m/s.

Explanation:

To find Tarzan's speed at the bottom of the swing, we use the principle of conservation of energy. Initially, Tarzan has gravitational potential energy (GPE) when the vine is level. As he swings down, this potential energy is converted into kinetic energy (KE).

At the bottom of the swing, assuming no energy loss to friction or air resistance, all GPE has been converted into KE. The formula for potential energy is U = mgh, where m is mass, g is the acceleration due to gravity, and h is height. The formula for kinetic energy is KE = ½mv², where v is velocity. Setting GPE equal to KE and solving for v gives v = √(2gh).

Substituting the known values, g = 9.8 m/s² and h = 22 m, we get:

v = √(2 × 9.8 m/s² × 22 m) = √(431.2 m²/s²) ≈ 20.76 m/s.

Therefore, Tarzan's speed at the bottom of the swing would be approximately 20.76 m/s.

Answers

number three is the answer im pretty sure

Answer:

The placement of effort force, resistance force, and fulcrum.

Explanation:

The placement of effort force, resistance force(which is the load to be moved), and fulcrum differentiates between the classes of levers.

Levers are divided into three classes and they are the first class, second class and third class lever. This machines are differentiated from one another depending on the position of their effort(E), Load applied(L) and the fulcrum (L).

For first class lever, the fulcrum is in between the load and the effort e.g a see-saw, scissors etc

For second class lever, the load is in between the fulcrum and the effort e.g a wheel barrow

For third class lever, the effort is in between the fulcrum and the load e.g a stapler

Also anything with a bunch of small particles can show resonance patterns for different frequencies, though typically something like sand is preferred to iron filings for price reasons, but basically if you set the paper on a vibrating plate or near a speaker, you could see the iron filings take on the resonance pattern of the plate/speaker, this is a good image search as well.

Why should we use the metric system in science?

Answers

scientist use the metric system so all experiments are conducted using the same weights and measures. scientists from different parts of the world can make sense of the numerical results of different experiments.
Final answer:

The metric system is used in science because it is universally adopted, easy to convert, and flexible across large and small numerical ranges. Every unit in the metric system increases by a factor of ten, an advantage not found in the U.S customary units. Metric units are easily scalable across different fields, making it a practical choice in science.

Explanation:

In the realm of science, it is more common to use the metric system, a measurement system adopted by most countries, except the United States. A core advantage of adopting this system is that every unit increases multiplicatively by a factor of ten. The base units of the metric system are the meter for length, kilogram for mass, and second for time.

One significant advantage of such system is its flexibility in scaling across extremely large or small numerical ranges simply through the use of an appropriate metric prefix, making it universal across various scientific and professional fields. For instance, in construction, one would most likely deal with meters, whilst in aviation, kilometers are more suitable, and nanometers find their use in optical design.

Unlike in the system of U.S customary units where conversions between various units might be complicated, the metric system offers simple conversions by merely shifting the decimal place of a number due to the sequential powers of 10 of the metric prefixes.

A boy of weight 500 N has feet with a total area of 200 cm2.
What is the pressure between him and the ground if he stands on both feet?
solution must be with formula.

Answers

Final answer:

The pressure between a person and the ground when standing on both feet can be calculated using the formula: Pressure = Force / Area. By substituting the given values into the formula, we can determine the pressure to be 25000 Pa.

Explanation:

The pressure between a person and the ground when standing on both feet can be calculated using the formula:

Pressure = Force / Area

Given that the weight of the boy is 500 N and the total area of his feet is 200 cm², we can substitute these values into the formula:

Pressure = 500 N / 200 cm²

Now, convert the area to square meters to maintain consistent units:

Pressure = 500 N / (200 cm² x (1 m/100 cm) x (1 m/100 cm))

Pressure = 500 N / 0.02 m²

Pressure = 25000 N/m² or 25000 Pa

So, the pressure between the boy and the ground when he stands on both feet is 25000 Pa.

A cyclic process is a process in which the system returns to its original state at the end of the cycle. An example of a cyclic process is the four-stroke gasoline engine, which operates according to the Otto cycle. This cycle is a repeating sequence of processes that convert heat into work. On the other hand, a non-cyclic process is a process in which the system does not return to its original state at the end of the cycle. An example of a non-cyclic process is irreversible processes, which depend on the path and do not return to their original state.

As the star shrinks, radiation of the surface increases and create pressure on the outside shell to push it away and forming a planetary nebula or white dwarf. The star is a ball of hot gases containing different kinds of elements at different cores. It has a very high temperature that radiates all throughout the Milky Way galaxy. The star has four main parts; the core, photosphere, chromospheres and corona. The outer core of a star located at the chromospheres contains mostly of hydrogen. Inside the hydrogen is helium then carbon, oxygen, neon, magnesium silicon and the inert gas. When a star releases energy it is due to the thermonuclear fusion of hydrogen into helium. 

You have designed a rocket to be used to sample the local atmosphere for pollution. It is fired vertically with a constant upward acceleration of 17 m/s2. After 30 s, the engine shuts off and the rocket continues rising (in freefall) for a while. (Neglect any effects due to air resistance.) The rocket eventually stops rising and then falls back to the ground. You want to get a sample of air that is 23 km above the ground.

Answers

In order to get a sample of air that is 23 km above the ground, the rocket must rise by that height.

Draw a diagram (shown below) t represent the problem.

The distance h₁ is traveled from A to B with an upward acceleration of 17 m/s² over 30 s. The distance traveled is
h₁ = (1/2)(17 m/s²)(30 s)² = 7650 m = 7.65 km

At point B, the velocity attained is
V = (17 m/s²)30s) = 510 m/s

The distance h₂ is traveled from B to C with gravitational deceleration of -9.8 m/s². The distance traveled is given by
(510 m/s)² - 2(9.8 m/s²)h₂ = 0
h₂ = 13270.4 m = 13.27 km

The total height attained by the rocket is
h₁ + h₂ = 7.65 + 13.27 = 20.92 km

This height falls short of the desired height of 23 km.

Answer:
The rocket does not travel high enough to sample the air at a height of 23 km.
