Answer: B
Explanation:
Newton's first law it's law of inertia.
An object at rest will remain at rest (or an object in motion in a straight line at a constant velocity will remain that way) unless it is acted by an unbalanced force.
In A for the ball to slow down and stop, an external force (like friction with air or the floor) needs to be taken in consideration.
In B we can see how we need to make a force on the wagon to make it move.
In C we have an other Newton 's law, force equals mass times acceleration (2nd law)
In D we can see how it does not move because the forces on the box are balanced.

Answer:</h3>
5.395 × 10^8 Watts
<h3>
Explanation:</h3>
<u>We are given;</u>
- Rate of flow is 1.1 × 10^6 kg/s
- Distance is 50.0 m
- Gravitational acceleration is 9.8 m/s²
We are required to calculate the power that is generated by the falling water
- Power is the rate of work done
- It is given by dividing the energy or work done by time
But; work done = Force × distance
Therefore;
Power = (F × d) ÷ time
The rate is 1.1 × 10^ 6 Kg/s
But, 1 kg = 9.81 N
Therefore, the rate is equivalent to 1.079 × 10^7 N/s
Thus,
Power = Rate (N/s) × distance
= 1.079 × 10^7 N/s × 50.0 m
= 5.395 × 10^8 Watts
The power generated from the falling water is 5.395 × 10^8 Watts
The blue light removes red parts of the color spectrum giving it a cooler color
