In order to know how long it has been falling for you take the final velocity "49m/s" and divide it by the acceleration "9.8m/s" and get 5, since you have been using seconds in the calculations the answer is 5 seconds. (Fun fact, it is actually 9.82m/s per second since it accelerates and they rounded it down.)
Unbalanced because if it is pushing then stopping, that means that it is unbalanced.
On isolated ground receptacles, the metal yoke is not allowed to be integrally bonded to the equipment grounding terminal of the receptacle.
Any device with two distinct switches or receptacles is a duplex device. It can be shaped to fit a Decora opening or a typical duplex plate opening. It should be noted that they can be combination devices with a switch/outlet, switch/pilot light, etc.
Because of grounding connection removal and receptacle, it is utterly undesirable to connect the two bare equipment grounding conductors together directly.
The equipment grounding conductor associated with those circuits must be connected to the box when circuit conductors are terminated on equipment inside a metal box to prevent unneeded current discharge.

Answer: Theory (D.)
Explanation:
A theory is based on years of careful scientific study, observation, and experimentation.
On the other hand, a law describes a phenomena without explaining it. An observation is merely a documentation of a phenomena and may or may not be explained. An experiment is a procedure done to test the effect of a specific variable, but does not necessarily explain WHY something occurs.
Gravitational force between sun and planet is given by,
Thus, The force of gravitation is inversely proportional to the distance.
Kepler's law states that the square of period of planet is proportional to cube of semi major axis of its orbit.
The time period of planet is more when the gravitational force is less.
Thus, planet Y is closer to earth because sun exert greater gravitational force than planet Z.
