Answer:
option C is correct
distance from the driver is 2 m
Explanation:
Given data
index of refraction of the water n = 1.333
driver height from ground= 1.5 m
to find out
What angle does light become maximally polarized and what distance from the driver will polarized
solution
we know that n1 for water = 1.33 and we know for air n2 = 1
so tan(θ) = n1 / n2
tan(θ) = 1.33 / 1
so (θ) = 53.06 degree
so for distance d will be calculate as
tan ( 90 - (θ) ) = height / distance
tan ( 90 - 53.06 ) = 1.5 / distance
distance = 1.5 / 0.7519
distance = 1.994 m = 2 m
so option C is correct
distance from the driver is 2 m
Answer:
Yes, they will also have the same acceleration. Acceleration is controlled by the amount of weight (def. amount of gravitational pull on a given object) that the ball has. For one ball to accelerate quicker than the other, it would need a propulsion element, which it does not.
Explanation:
"Acceleration" is a change in speed, or direction of motion, or both.
The calculation for kinetic energy is this
KE = 1/2mv^2
KE = 1/2(50)(7^2)
KE = 1/2(49•50)
KE = 1225 kgm^2/s^2.
Or simply 1225 J.
