Neither does. Their effects are <em>EQUAL.</em>
Potential energy = (MASS) x (gravity) x (HEIGHT)
You should be able to look at this formula and see that the effects of mass and height are equal. Gravitational potential energy is directly proportional to both of them.
If you want to increase the potential energy of some object, say, by 42%, you can do it either way ... either increase the object's mass by 42%, OR raise the object 42% higher than it is now. Either of those changes will have the same effect on the object's potential energy.
Answer:
U= 4.1×10^{-3} J
Explanation:
Given:
Young's modulus E= 2.5×10^5 N/m^2
thickness of material L_o =3.0 mm
Area A= 0.50 cm^2
ΔL= 1.0 cm
The potential energy is given by
U= 1/2FΔx
therefore
now putting values we get
U= 4.1×10^{-3} J
Yes. Acceleration means any change in speed or direction of motion. When an object coasts in a circular orbit at constant speed around the Earth, its direction is constantly changing. The acceleration is "CENTRIPETAL", which points toward the center of the circle.
C. Lack of mates. If they cannot reproduce enough, their size will reduce.
