Answer:
D.) will not move unless acted on by another force
Explanation:
This is well-explained by Newton's first law, also called "Law of inertia", which states that:
"an object in state of rest (or in state of motion with constant speed) will remain at rest (or will continue moving with constant speed) unless acted upon an unbalanced force".
In the situation described in the problem, we have a bowling ball at rest on the table. The ball is acted upon two balanced forces: the force of gravity, downward, and the normal reaction of the table, upward. According to the First Newton Law that we mentioned above, the ball will remain in its state of rest unless it will be acted upon another unbalanced force that can accelerate it.
I believe the answer is energy
Answer:
Graph 1 matches with B, 2 with A, and 3 with C.
Explanation:
Graph 2 shows a car whose distance part of the graph is not going up or down, while the time going up. That means that the car is stopped. Graph 1 shows a straight line, meaning that the car is traveling at a constant speed. Graph 3 is a curved line, meaning the speed of the car is changing somehow, and since the line is becoming more horizontal, the car is getting slower.
Answer:
vp = 0.94 m/s
Explanation
Formula
Vp = position/ time
position: Initial position - Final position
Position = 25 m - (-7 m) = 25 m + 7 m = 32 m
Then
Vp = 32 m / 34 seconds
Vp = 0.94 m/s
Answer:
The crests of the sound wave are spaced closer together.
Explanation:
the wavelength between successive crests is decreased due to the motion of the truck in the same direction as the sound
