These waves most likely belong to the part<span> of the electromagnetic spectrum that contains radio waves, since radio waves have the lowest frequency of any of the other waves.</span>
it's either the first or second choice
Answer: 1
an object positioned at some height in a gravitational field
Explanation:
Gravitational potential energy of an object is the energy stored due to position of the object or position at certain height relative to zero position.
Gravitational potential energy can also be expressed as object position at some height above or below zero position in a gravitational field
I think 1 and 2 make sense. But 1 make more sense than 2
Light gates are more reliable. When using a manual stop watch, it is difficult to stop it at an exact time. A light gate is able to detect when an object passes through a 'gate' with the infrared transmitter and receiver.
In a surface wave (like water) the water goes up and down, but the wave travels across (parallel to) the surface.
