Answer:
it gives rise to vibrating in one plane.when light passes through second polarizing crystal no light passing through.
Explanation:
in the second polarizing crystal only darkness emerges.
Answer:
(a) the work done by the student is 110.1 J
(b) The gravitational force that acts on the amplifier is 102.9 N
Explanation:
Given;
mass of the amplifier, m = 10.5 kg
initial position of the amplifier, x₀ = 1.82 m
final position of the amplifier, x₁ =0.75 m
The dispalcement of the amplifier Δx = x₁ - x₀ = 1.82 m - 0.75 m = 1.07 m
(b) The gravitational force that acts on the amplifier;
F = mg
F = 10.5 x 9.8
F = 102.9 N
(a) the work done by the student is calculated as;
W = FΔx
W = 102.9 x 1.07
W = 110.1 J
Well,
The sun's energy is produced mainly in the core, which has sufficient temperature to initiate nuclear fusion.
Hydrogen --> Deuterium --> Tritium --> Helium --> Beryllium? --> Carbon --> ? --> Silicon --> Iron/Nickel = Most massive stars<span />
Answer:
False, it will just dissolve slowly
You would do distance divided by speed. So 150÷3, which would equal 5km per hour.
