Answer:0.667 N
Explanation:
Given
It is noticed that Frictional Force is 0.2 N
Coefficient of kinetic Friction
We know Friction Force is given by
therefore
Answer:
644 W/m²
0 W/m²
Explanation:
= Initial intensity of light = 1288 W/m²
= Angle of filter
Intensity of light is given by
The intensity of the transmitted light is 644 W/m²
The intensity of the transmitted light is 0 W/m²
Answer:
Explanation:
F = Force on the sled = 63 N
m = Mass of sled = 28.7 kg
= Coefficient of kinetic friction = 0.169
g = Acceleration due to gravity =
The force balance of the system is given by
The acceleration of the sled is .
