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:
we cant see the digram bro
Explanation:
To find what a is, consider the equation v=at (v=velocity, a=acceleration, t=time interval), making a=v/t. Take the given v of 853m/s, and divide that by your time IN SECONDS, so 1.2ms=1.2*10^-3s.
a=(853)/(1.2*10^-3)=7.11*10^5 m/s^2.
Now Having F=ma, where a is your acceleration, and m=mass (which is 49*10^-3 kg),
F=(49*10^-3)(7.11*10^5)=3.48*10^4 N
Hope this helps!
Answer:
The answer is D.
Explanation:
Just like how cold air falls and warm air rises the same is with water.
Also the places with the coldest water is the north and south pole. The equator is relatively always warm so yeah.
