Answer:

The mass would remain the same and the weight would change

Explanation:

A rock is made out of matter; matter is never destroyed or made. Mass is the composition of matter in the rock. Mass is always constant.

Weight is a force, measured in Newton. The formula for weight (force) is;
force = mass \times acceleration
The force in this case is the weight and the acceleration is the gravitational pull. Since the mass is constant and the gravitational pull of earth and of the moon differs, the the force changes.

On the surface of the earth the weight of an object is 200 lb. Determine the height of the
siniylev [52]

Answer:

The height of the  object is 5007.4 miles.

Explanation:

Given that,

Weight of object = 200 lb

We need to calculate the value of Gmm_{e}

Using formula of gravitational force

F=\dfrac{Gmm_{e}}{r^2}

Put the value into the formula

200=\dfrac{Gmm_{e}}{(3958.756)^2}

200\times(3958.756)^2=Gmm_{e}

Gmm_{e}=3.134\times10^{9}

We need to calculate the height of the  object

Using formula of gravitational force

F=\dfrac{Gmm_{e}}{r^2}

Put the value into the formula

125=\dfrac{200\times(3958.756)^2}{r^2}

r^2=\dfrac{200\times(3958.756)^2}{125}

r^2=25074798.5

r=\sqrt{25074798.5}

r=5007.4\ miles

Hence. The height of the  object is 5007.4 miles.

a metal bal is held at rest H=65.0 cm above the floor. The ball is released with no initial velocity. How much time does it take
Fofino [41]

<u>Answer: </u>

Metal ball will take 0.364 seconds to reach floor.

<u>Explanation: </u>

Initial height from ground = 65 cm = 0.65 meter

We have equation of motion , s= ut+\frac{1}{2} at^2, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

In this the velocity of body in vertical direction = 0 m/s, acceleration =acceleration due to gravity = 9.8 m/s^2, we need to calculate time when s = 0.65 meter.

Substituting

0.65=0*t+\frac{1}{2} *9.8*t^2\\ \\ t = 0.364 seconds

So it will take 0.364 seconds to reach floor.
