Answer</h2>
The weight will be 1/6 time less on the moon than earth.

Explantion</h2>
The varies the size of the object the effects the of gravitational pull will vary. As the moon is smaller than the size of the earth, then it has less gravitational pull. The value of gravity is on the earth but in the moon, it will reduce 1/6 times and will be . The weight change by change the planet but mass remain same. In the given question the weight is 150g. So,
at earth
by rearranging
On moon
The change in mass was because of gravitational pull
Assuming negligible air resistance, the shell travels at a constant horizontal velocity equal to what it had immediately after leaving the barrel. The shell is in the air until hitting the target; the length of this period of time is therefore directly proportional to the distance between the barrel and the target.
The shell hits the target below where it was aimed at for it experiences gravitational pull during its flight. With the barrel pointed "parallel to the ground" the shell shall experience no initial vertical velocity, meaning that it its undergoing a freefall on the vertical direction. and are therefore the respective vertical displacements of the two trials.
The formula below relates the vertical displacement to the gravitational acceleration and the time duration of the freefall :
Let and be the duration of the shell's flight on the first and second trials, respectively; Thus
Answer:
gravity is vital because as we know space curves around objects like planets, in this curvature is our atmosphere and a gravitational pull holding everything in, without this curvature we would not have any gravitational pull.
Hope it helps!!!
Explanation:
125 because f=ma so you would use 100=mx0.75
