The correct answer for the question that is being presented above is this one: "action force." Using a hammer to drive a nail, it is the reaction force that brings the motion of the hammer to a stop but the action force that drives the nail into the wood.
Explanation:
The reaction force is what presents you drive because it acts on you. Newton's Third Law of Motion describes that forces perpetually come in action-reaction pairs. The Third Law states that for every action force, there is an identical and opposite reaction force. The ball exerts an equal and opposite force on the bat.
Answer: 3.32x10^-4
Explanation: Works for Acellus
Answer:
Electrons accelerated to high velocities travel in straight lines through an empty cathode ray tube and strike the glass wall of the tube, causing excited atoms to fluoresce or glow.
Answer:<u><em> (Light and sound both require a medium in which to travel)</em></u>
Explanation: <em>Sound and light always have the means to travel and get somewhere as fast as possible. Light is always faster than sound but it does not matter because they both almost always get where they want.</em>

<em>Part 2. light was composed of particles or waves, a wave-particle dual nature soon was found to be characteristic of electrons as well. The evidence for the description of light as waves was well established at the turn of the century when the photoelectric effect introduced firm evidence of a particle nature as well. basically when light hits a metal object . :)</em>

Answer:
43,555 W
Explanation:
Since the speed is constant, this means that the force applied to lift the equipment is equal to the weight of the equipment. So we can write:
where
m = 1000 kg is the mass
is the acceleration due to gravity
So,
Then the work done in lifting the equipment is:
where
d = 200 m is the displacement of the equpment
Substituting,
Finally, the power used to lift the equipment is the ratio between the work done and time taken:
where
t = 45 s is the time taken
Solving,
