In physics, potential energy is calculated as ‘mass × acceleration due to gravity × height’

So,

P.E. = 70 kg × 10 m/s² × 10 m

P.E. = 7000 Joules

Answer: 7000 joules

Explanation: The potential energy is the energy "stored" by the object.

For objects that are lifted in the y-axis, the potential energy can be calculated as:

U = g*h*m

where g is the gravity's acceleration, h is the height and m is the mass of the object.

Here, g = 10m/s^2, m=70kg and h = 10m

U = 10m/s^2*70kg*10m = 7000 (m/s)^2*kg = 7000 joules

Mass of marble  is the constant variable in this experiment. Hence, option (C) is correct.

A control variable, also known as a scientific constant, is an experimental component that remains constant (controlled) and unaltered over the course of a research.

If control variables were not maintained constant throughout the experiment to examine the relative relationship between the dependent variable (DV) and independent variable(IV), the outcomes of the experiment could be significantly impacted .  The experimenter is not very interested in the control variables themselves.

In this experiment, Mass of marble remains constant. So, Potential energy of marble is the constant variable in this experiment. Hence, option(C) is correct.

False gases are easily dissolved in cold water

Answer: The given statement is false.

Explanation:

Relation between kinetic energy and temperature is as follows.

                [tex]K.E \propto \frac{3}{2}kT[/tex]

As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.

At high temperature, gases are desorbed, that is, they readily escape into the atmosphere.

Therefore, when gas particles move more slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.

Hence, at low temperature only gases are absorbed.

Thus, we can conclude that the statement gases are absorbed more easily in hot water, is false.

Answer ;

Note : Satellite completes  one orbit in the same time the earth rotates one about its axis

circumference of the orbit = 2 ×π × 4.23×10⁷  (similar to the earth orbital speed

The time of earth/orbit traveled  = 23.93 hrs ,

Speed of the orbit = (distance) ÷ (time)

                              = circumference ÷ time

                              = (2 ×π × 4.23×10⁷) ÷ 23.93   (1 hr = 3600 sec.)

                              = 3085.14 m/s

The orbital velocity is 3085.14 m/s

Given that,

Capacity = 3.6 gallons per minutes

Convert it into milliliters per seconds

Since, 1 gallon = 3.79 liters

1 liters = 1000 milliliters

Capacity= (3.6*3.79*1000)/(60)

Capacity = 227.4 milliliters per second.

3.6 gallons per minute is equivalent to a flow rate of 227.4 milliliters per second.

Here are the steps to convert 3.6 gallons per minute to milliliters per second:

Convert gallons to liters: 3.6 gallons * 3.79 liters/gallon = 13.644 liters per minute.

Convert minutes to seconds: Since there are 60 seconds in a minute, divide 13.644 liters by 60 to get the flow rate in liters per second: 13.644 liters / 60 seconds = 0.2274 liters per second.

Convert liters to milliliters: Since there are 1,000 milliliters in a liter, multiply 0.2274 liters by 1,000 to get the flow rate in milliliters per second: 0.2274 liters * 1,000 milliliters/liter = 227.4 milliliters per second.

Therefore, 3.6 gallons per minute is equivalent to 227.4 milliliters per second.

== You're pushing the load straight along the horizontal surface at a constant speed.

== The speed and direction of the load are not changing, so there is no acceleration.

== From Newton's 2nd law of motion, we know that  F = m A .  Since A=0, F must also be zero.  That means NO NET FORCE is acting on the load.

== But how can that be ? You're pushing it with 90 N !

== The NET force is zero.  So something else must be pushing the box, also with 90 N of force, exactly opposite to YOUR force, and they add up to zero.

== THERE's your force of friction !

In this case, the force of friction is 90.0 N. This is inferred from the fact that the object is moving at a constant speed, implying that the force applied is countered by an equal force of friction. This is an application of Newton's first law of motion.

The force of friction can be determined by using the basic principles of physics. In the scenario presented, the box is being moved at a constant speed, which implies that the force of friction is equal to the force applied, 90.0 N. This is because when an object moves at a constant speed, it suggests there is a balance of forces meaning the force you're applying (90.0 N in this case) is battling against an equal force in the opposite direction, this opposing force being the force of friction.

This applies the principles of Newton's first law - an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This equilibrium of forces is what's keeping the box moving at a constant speed.

Answer:

The correct answer option is: the law of inertia.

Explanation:

Newton’s first law of motion is sometimes described as the law of inertia.

According to the first law of Newton, an object will remain at rest or in uniform motion in a straight line until and unless an external force is applied on it.

This law is also referred to as the law of inertia since the object tries to remain in its present or existing state of motion, showing resistance to bring change in its state.

Answer:

Explanation:

Answer:

The radius of the path is increased

Explanation:

The centripetal force is represented by the equation:

[tex]F=\frac{mv^2}{r}[/tex]

where [tex]F[/tex] is the centripetal force, [tex]m[/tex] is the mass of the object on the circular path, [tex]v[/tex] is its velocity and [tex]r[/tex] the radius of the circle

From the equation we can observe that the centripetal force and the radius of the circular path are inversely proportional: if the radius increases the force decreases, and if the radius decreases the force increases.

Thus, the complete sentence is:

The magnitude of the centripetal force acting on an object traveling in a horizontal circular path will decrease and if the radius of the path is increased

The magnitude of centripetal force will decrease if the radius of the circular path increases, as the force is inversely proportional to the radius of curvature while being directly proportional to the square of the velocity and the mass of the rotating body.

The magnitude of the centripetal force acting on an object traveling in a horizontal circular path is influenced by several factors, including the mass of the object, its velocity, and the radius of the path. Newton's second law implies that the centripetal force, which is always directed towards the center of rotation, is essential in maintaining circular motion. If we use the formula Fc = mv2/r, where Fc is the centripetal force, m is the mass, v is the velocity, and r is the radius, it is clear that the centripetal force is directly proportional to both the mass and the square of the velocity, but inversely proportional to the radius.

Therefore, an increase in the radius of the circular path would result in a decrease in the centripetal acceleration and thus, a decrease in the centripetal force, as centripetal acceleration (ac = v2/r) is directly proportional to the square of the object's velocity and inversely proportional to the radius of curvature (r).
