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
That was Johannes Kepler.
He couldn't say why that should happen. But he was able to show that
if we <em><u>assume</u></em> the the sun is in the center of the solar system, and <em><u>assume</u></em>
that the planets revolve around the sun in elliptical orbits, and <em><u>assume</u></em> that
the farther a planet is from the sun the longer it takes to orbit the sun, then
<em>that matches everything that we see the planets actually doing in the sky</em>.
Then Isaac Newton came along, and wrote down a short, simple formula
for the force of gravity. And then he showed that <u>IF</u> his formula for gravity
is correct, then the planets MUST do everything that we see them actually
doing in the sky, and they MUST behave according to Kepler's laws.

Answer:
A hypothesis predicts the value of a dependent variable given an independent variable:
If a person weighs 50 kg (independent variable) the weight hypothesis predicts that W = 50 * 9.8 = 490 N (the dependent variable)
So those three should be present in an investigation
Answer:
Explanation:
A uniform circular motion is an example of accelerated motion.
When an object is moving in a uniform circular motion, there is a centripetal force acting towards the centre of the circular path and then a centrifugal force is also acting away from the centre of the circular path. The magnitude of the centripetal force and the centrifugal force is same but the direction is opposite to each other. So, it is explained by the Newton's third law.
