Answer:
The answer to your question is the Photoelectric effect.
Explanation:
What is the magnitude of force required to accelerate a car of mass 1.7 × 10³ kg by 4.75 m/s²
Answer:
F = 8.075 N
Explanation:
Formula for force is;
F = ma
Where;
m is mass
a is acceleration
F = 1.7 × 10³ × 4.75
F = 8.075 N
<u>Answer:</u>
148.4 J
<u>Explanation:</u>
We are given that the efficiency of a pulley system is 74.2% and we are to calculate the useful work done if we perform 200 J of work
We know that efficiency is basically the measure of how efficient a process is.
The formula of efficiency is given by:
<em>Efficiency = useful energy output / total energy input</em>
So substituting the given values in the above formula:
0.742 = Useful energy / 200 J
Useful energy = 148.4 J
