Acceleration = (change in speed) / (time for the change)

Change in speed = (New speed) - (old speed)

Change in speed = (0.8 m/s - 0.5 m/s) = 0.3 m/s

Time for the change = 3 seconds

Acceleration = (0.3 m/s) / (3 s)

<em>Acceleration = 0.1 m/s²</em>

(a hair more than 1 percent of 1 G.)

All of that fluff at the beginning is interesting, but completely irrelevant
to the question. The question is just asking for the mass of an object
that weighs 3.6N on Earth.

Weight = (mass) x (acceleration of gravity)

3.6N = (mass) x (9.8 m/s²)

Divide each side
by 9.8 m/s : Mass = 3.6N / 9.8 m/s² = <em>0.367 kilogram</em> (rounded)

If light needs matter , how doe it move through space? this is my first question.

Light is not matter. A photon is not matter because it has no mass. So rephrase your question...

The energy photon affects which property of light

Triss [41]

Answer:

photoelectric effect

Explanation:

When the energy from photons is absorbed by matter, the matter can emit electrons. This process is called the photoelectric effect. The photoelectric effect is a property of light that is not explained by the theory that light is a wave.
