Answer:
Light comes in different colors like radio, ultra violet, gamma-ray, etc, and they are invisible to the bare eye
Explanation:
Answer:
Explanation:
Balance force ( W ) = 85 N
a) moving upward with constant velocity (V ) = 7.9 m/s.
The reading will not change since it is moving with constant velocity
W = 85 N
b) Moving upward with V = 7.9 m/s and decelerating at the rate of (a ) = 1.1 m /s²
The net force ( F ) = W - ma
where m = W/g = 85/9.81 = 8.6646 kg
F = 85 - 8.6646 * 1.1 = 75.4689 N
Answer:
I feel like to demonstrate you would use an elastic band as the material. You obviously have to put force in order to see how far it stretches. From this you can also find about its resistance and durability
Also you have to make sure the distance between the two hands are equal as you want an accurate result.
