1 answer:
Answer:
Photons.
Explanation:
Einstein explained the photoelectric effect by proposing that light is transmitted, not in the form of continuous waves, but in the form of many tiny, discrete packets of energy called photons. Photons are massless and chargeless particle. The energy of a photon is given by :
f is the frequency of photon.

The net force acting on the car is equal to -12000 Newton.
<u>Given the following data:</u>
- Mass = 1,200 kg
- Initial velocity = 30 m/s.
- Final velocity = 0 m/s (since the car came to a stop).
- Time = 3 seconds.
To determine the net force acting on the car:
<h3>How to calculate the net force.</h3>Mathematically, the net force acting on the car is given by Newton's Second Law of Motion:
<u>Where:</u>
- m is the mass.
- t is the time.
- u is the initial velocity.
- u is the final velocity.
Substituting the given parameters into the formula, we have;
Net force = -12000 Newton.
