Answer:
The answer is they utilized light in a few spots to enlighten the subjects and to demonstrate their volume as masses.
Explanation:
That is the reason every one of the particles that move at the speed of light (e.g. photons) have zero rest mass. As a molecule with mass methodologies the speed of light, its vitality increments and winds up unbounded at the speed of light, which is the motivation behind why it can never be quickened to achieve that speed. However, you can state that the photon has relativistic mass on the off chance that you truly need to. In current wording, the mass of a protest is its invariant mass, which is zero for a photon.

Answer:
3.8 m/s²
Explanation:
Average acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (25 m/s − 0 m/s) / 6.5 s
a ≈ 3.8 m/s²
Answer:
5.33 cm
Explanation:
The lens equation states that:

where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
In this problem,
p = 8 cm
q = 16 cm ( the sign is positive since the image is real, which means it is formed on the other side of the lens)
Substituting into the equation,
