Answer:
B The force that the floor of the elevator exerts on you and the force that you exert on the floor of the elevator
Explanation:
A. is incorrect because the force of gravity on you will always stays the same while the force of the elevator exerts on you changes as it takes you upward
B. is correct in accordance to Newton's 3rd law of action and reaction forces.
C. is incorrect because gravity force stays the same while the force that you exerts on the floor change as elevator moving upward.
D. is incorrect although it states Newton's 1st law. However there can still be pair of forces (part B) that could counter balance each other among other forces.
Answer:
Yes, the velocity of the object can reverse direction when its acceleration is constant. For example consider that the velocity of any object at any time t is given as: ... At At t = 0 sec, the magnitude of velocity is 2m/s and is moving in the forward direction i.e.v (t) = -2.
The correct answer for this question is 160.89 m².
The square footage of a newspaper ad for an apartment is = 1730ft²
We know that one square foot equals 0.093 square meters.
We can determine the area in square meters using the above conversion.
Total square meters = 0.093×1730ft² (or) 1730÷10.7
= 160.89 m²
