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
“to predict the speed that a coaster will reach before it is ever placed on the track. ... When coaster goes up by height h then its gravitational potential energy increases by the amount m.g.h where m = mass of coaster, h = height of coaster and g = gravitational acceleration due to Earth”
The fastest Thing in the world is said to be light.
Its speed has been measured to be an incredible 299,792,458 m / s
A
The horizontal force cancels out. The two 4Ns go in opposite directions. So they don't affect the outcome.
The Vertical force is 6N up - 2 N down = 4 N Up
Answer 4 N up
B
The horizontal and vertical forces cancel out. Each gives 3N - 3N =0
The net force is 0
C
You only have horizontal forces on this one
5N - 3N = 2N
The answer is 2N to the right.
