our boss asks you compare two sound waves and determine which has the higher frequency. Wave A has a period of 4⁄100 second and Wave B has a perio of 1⁄7 second.

Answers

Answer 1
The periodic time is the inverse of frequency. This means that:
Period = 1/frequency
Therefore,
Frequency = 1/period

For wave A:
period = 4/100
frequency = 1/(4/100) = 100/4 = 25 Hz
For wave B:
period = 1/7
frequency = 1/(1/7) = 7 Hz

Based on this, wave A has higher frequency.
Answer 2
Wave A- period = 4/100 and the frequency = 1/(4/100) = 100/4 = 25 Hz
Wave B- period = 1/7 and the frequency = 1/(1/7) = 7 Hz

Wave A has a higher frequency.

Which of the following best explains why mutations cannot cause evolution?

Answers

A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. Most disease-causing gene mutations are uncommon in the general population. However, other genetic changes occur more frequently. Genetic alterations that occur in more than 1 percent of the population are called polymorphisms. They are common enough to be considered a normal variation in the DNA.

Stars with the longest lifetimes are not always the farthest from Earth, as factors like mass and luminosity influence a star's lifetime independently of its distance from Earth.

No, the star with the longest total lifetime is not necessarily the farthest from Earth. Stars can have different lifetimes based on their mass and luminosity, which affect how fast they burn their fuel. Distance from Earth is independent of a star's lifetime, and factors like apparent brightness and luminosity can play a role in how we perceive a star's distance.

2. Which of the following is Not true about the noble gases? a. They have completely filled energy levels. b. They have weak intermolecular forces. c. They do not bond with other elements in nature. d. They have boiling points above room temperature.

Answers

C because Noble gasses typically do not create chemical bonds. 
Final answer:

The statement that is NOT true about noble gases is 'They have boiling points above room temperature.' Noble gases have low boiling and melting points due to weak London dispersion forces, they have filled energy levels, and they do not generally bond with other elements because of their stability.

Explanation:

The statement that is NOT true about noble gases is 'd. They have boiling points above room temperature.' Noble gases, such as helium, neon, argon, krypton, xenon, and radon, have very low melting and boiling points.

This is due to the weak London dispersion forces that exist between the individual atoms. These weak forces can barely hold the atoms together which results in the low boiling and melting points.

Additionally, noble gases have completely filled energy levels and are stable, leading to the fact they rarely bond with other elements in nature. This stability is responsible for their name 'noble' as they are 'above' interacting with others, similar to nobility. So, the statements 'a. They have completely filled energy levels', 'b. They have weak intermolecular forces', and 'c. They do not bond with other elements in nature' are all accurate.

Final answer:

According to Freud, "the id is the largest part of a person's personality" because it encompasses instinctual drives and operates entirely in the unconscious.

Explanation:

According to Freud, the largest part of a person's personality is the unconscious, which includes the id, ego, and superego. While the ego operates in the conscious and serves as the mediator between the id and the superego, it is the id that forms the largest component, as it encompasses basic instinctual drives and is entirely unconscious. Freud's theory posits that the unconscious mind holds repressed memories and desires that significantly influence conscious behavior and personality development, with the id being a primary force driving pleasure-seeking behavior.

Which of the following statements correctly compares ultraviolet and visible light?

A. UV light has more energy than visible light
B. UV light has lower frequency than visible light
C. UV light has a longer wavelength than visible light
D. UV light has a smaller amplitude than visible light

Answers

I believe that the answer to this question is the letter A!

Final answer:

UV light has shorter wavelengths and higher frequencies than visible light, resulting in more energy, which is why statement A is correct.

Explanation:

The question asks which statement correctly compares ultraviolet (UV) and visible light. The correct answer is A, which states that UV light has more energy than visible light. This statement is accurate because in the electromagnetic spectrum, UV light has shorter wavelengths and higher frequencies than visible light, both of which contribute to its higher energy levels. Unlike visible light, the higher energy of UV light can be enough to break chemical bonds, such as those in DNA, which can lead to cellular damage and is why it is often blocked by sunscreen and sunglasses.

F) Sea floor spreading

Answers

E)Outlines of the continents fit together like puzzle pieces?

Final answer:

Evidence for plate tectonics includes similar landforms across continents, the distribution of fossils in disparate geographic areas, the fit of continental outlines, and the process of sea floor spreading.

Explanation:

The evidence for the theory of plate tectonics is multifaceted and includes geologic, paleontologic, and morphologic observations:

Land forms such as mountain ranges that have similar ages, composition, and structure despite being separated by oceans are evidence of plate tectonics. For example, the Appalachian Mountains in North America are geologically similar to mountain ranges in Greenland and Europe, suggesting that they were once connected.Fossils provide evidence for plate tectonics. For instance, fossils of tropical plants found in northern Canada indicate that the area was once located in a different climate, possibly closer to the equator, before the plates shifted. Additionally, the presence of the freshwater reptile Mesosaurus' fossils in both South America and Africa suggests these continents were once joined.The complementary fit of the continental outlines, much like puzzle pieces, supports the idea that continents have drifted apart over time.Sea floor spreading is a process observed at the mid-ocean ridges, where new crust is generated and pushes plates apart, providing direct evidence of tectonic movements.

By piecing together this evidence, scientists have been able to support the framework of plate tectonics, providing a comprehensive explanation for continental drift and the dynamic nature of the Earth's surface.

A person drives 20 miles north and 45 miles east. What is the angle of the resultant straight to their destination?

Answers

Let us take east and north as the positive x and y-axes should the motion be plotted in a cartesian plane. Thus, the x value is 45 miles and the y value is 20. The tangent of an angle is equal to the ratio of y to x.

   tanθ = y / x

Substituting,

   tanθ = 20/45 = 0.44

The value of θ is 23.96°.

How can the rate of a reaction be increased?

Answers

Answer and explanation;

-Rate of reaction is the speed at which the reactants are converted to products.

-Rate of reactions depends on a number of factors which includes;

Concentration of reactants; increasing the concentration of reactants increases the rate of reaction. Temperature; An increase in temperature results to an increased rate of reaction. Increase in temperature increases the kinetic energy of molecules thus the collision per unit time also increases and hence the rate of reaction increases.Decreasing the size of particles of solid reactants also increases the rate of reaction. This is because smaller particles increases the surface area on which more collisions can occur thus a faster rate of reaction.Adding a catalyst also increases the rate of reaction. This is because catalysts lower the activation energy of reactants, minimum energy require by reactants for the reaction to take place. This thus increases the rate of reaction.

Explanation:

There are many factors that are responsible for increasing the rate of reaction.

(1) Temperature: If the temperature increases, the kinetic energy of the molecules also increases. Hence, the collisions and ultimately the rate of reaction increases.

(2) The concentration of reactants: Higher the concentration, more will be the collision and hence more will be the rate of reaction.

(3) Pressure: Pressure is also directly proportional to the rate of reaction.

(4) Catalyst: Adding a catalyst increase the rate of reaction. Because it decreases the activation energy of the reactants. Hence, a small amount of energy is required by the reactants.

Hence, the above factors increases the rate of reaction.
