Answer: The angle of incidence at which the light will fully be polarized is 60°
Explanation:
To find out the angle of incidence θB for which reflected light is fully polarized we use the equation
n1 sinθB = n2sin(90°− θB) = n 2cosθB
Since n1 is the index of refraction for medium 1 and n2 is the medium of refraction for medium 2 we then solve the equation to get
θB = tan −1 (n2/n1)
= tan −1 (2.22/1.28)=60.0°
It’s best to help a scientist base a hypothesis off questions
KE and PE are the same so it would end up being 300=3x9.8xm and work backwards to find 300=29.4m divide and get 10.2 significant figures will make it 10
That's a pretty slippery topic. I think the big brains and high-power cosmologists can spend a month discussing it and not have an answer.
For US ... people who are not big brains or high-power cosmologists ...
I think the best way to think about it is that MASS causes inertia.
The more mass an object has, the more inertia it has. And all of the
math and Physics that describe the behavior of mass can also be
understood as the results of inertia.
