Answer:
When temperature is held constant, the pressure and volume of a gas are not proportional.
Explanation:
That is Boyle's Law
There are three forces acting on the book.
1. Force due to gravity
2. Force exerted downward by the hamster
3. Normal Force in reaction to the downward forces
Since the book is not moving, the net force is zero. The summation of all forces must be zero. Then we could find the normal force which is unknown (denoted as x).
∑F = -(4 kg)(9.81 m/s2) - 3 N + x =0
∑F = -39.24 N - 3N + x =0
x = 42 N
Therefore, the normal force is 42 N.
True because my mom said to me this morning that i have to take my breakfast
Answer:
V = V0 + a t
V = 75 - 9.8 * 3 = 45.6 m/s
