Answer:
if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
Explanation:
The incident light is generally random, that is, it does not have a polarization plane, when the first polarized stops by half, this already polarized light arrives at the second polarizer and the causticity passes
I = I₀ cos² θ
therefore if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
An object with a greater mass will have more inertia as it takes more force to change their motion.
So, 50kg. (answer)
Answer:
5 N
Explanation:
The work done by a force on an object is (assuming that the direction of the force is parallel to the displacement of the object):
where
F is the magnitude of the force
d is the displacement of the object
In this problem, we know that:
W = 35 J is the work done
d = 7 m is the displacement of the object
Therefore, we can re-arrange the equation to calculate the force applied:
