A wave is basically propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.
Answer:
gravity
Explanation:
Even when satellites are thousands of miles away, Earth's gravity still tugs on them. Gravity—combined with the satellite's momentum from its launch into space—cause the satellite to go into orbit above Earth, instead of falling back down to the ground.
Answer:
They would all most likely have the same weight
Explanation:
Think about it the smaller the person or object the smaller the weight. But theyre all the same height now. And its not like you don't have any weight in the moon. So in conclusion they would all be the same weight
Explanation:
The charge (positive or negative) is always on the surface in the conductors. So, if the plates have substantial thickness, the charge is distributed throughout the surface. We know from the question that the bottom plate is charged positively, so an equal amount of negative charge must be distributed on the lower surface of the upper plate.
The direction of the E-field is always directed from positive to the negative charge. Since the plates have flat surfaces, the electric field lines are straight, except the edges. In most college level questions this effect is negligible, that is why in most questions the plates are considered very large.
John's truck has more mass than his brother Thomas' truck.
John's truck has more inertia than Thomas' truck.
If both trucks get equal force, John's truck will accelerate more slowly than Thomas' truck.
John's truck needs more force to accelerate.
If both trucks are just sitting there, John's truck needs more force to start moving.
We don't know anything about the efficiency of either truck. Or the efficiency of either brother, for that matter.
