Answer:
0.50
Explanation:
The maximum height is given by here h is the maximum height u is the initial velocity and is the angle of projection
So we can see from the relation that height is universally proportional to the gravity now in question it is given that the planet has the twice the surface gravity than the earth so the height will be half
Answer:
Bc the ocean is blue and the water reflects to the sky ;-;
The best and most correct answer among the choices provided by your question is the second choice or letter C. A solar-powered car converts light energy to mechanical energy.

Answer:
F = 25 N
Explanation:
The work done by any force is given as the product of the force and displacement produced by the application of that force. Therefore, the work done by the dog when it pulls the rope attached to the box can be given by the following formula:
where,
W = Work done by the dog while pulling the rope = 250 J
F = Force of pull applied by the dog = ?
d = displacement of the box across the floor = 10 m
Therefore,
<u>F = 25 N</u>
