Answer:
Polarized glasses contains a special filter that block dangerous intensity of lights which are reflected by flat surfaces and they help in reducing glare and discomfort
Explanation:
Sunlight scatters in all the direction. But when this light strikes with the flat surfaces, then the light which is reflected by the flat surface tend to become polarized, means the reflected light will travel in all directions. This reflecting light creates a dangerous intense light that causes glare and reduces visibility.
Polarized glasses contains a special filter that block this type of dangerous intensity lights, help in reducing glare and discomfort.
Therefore, by the above discussion it can be say that the polarized sunglasses particularly effective in reducing glares.

This problem is going to be pretty long to solve. So, prepare.
We’re interested in the change in our x position. So we have to break the velocity vector up into its components. Do cosine of 50 and then multiply by the magnitude of the velocity. I got 20.57m/s. That’s our initial velocity. And remember, horizontal acceleration is zero. The vertical acceleration, or any vertical component, has no effect on the horizontal components. In order to solve this problem, we want to utilize this equation:
Change in x-position = Vix*t
Let’s solve for time, which is dependent on the vertical components. The projectile will stop when it vertically hits the ground. Generally you want to use this equation for solving for time:
Yf = Yi + Viy*t + 1/2at^2
We didn’t solve for the vertical component yet, so let’s do that now. (Sine of 50)*(32) = 24.51m/s
Let’s now plug everything in:
0 = 0 + 24.5t - 4.9t^2
0 = 24.5t - 4.9t^2
0 = t(24.5 - 4.9t)
-24.5 = -4.9t
t = 5 seconds
The hard stuff is pretty much over. Put that 5 seconds into the other equation I said we wanted to use to solve the problem
Change in x-position (range) = (20.57)*(5)
= 102.85 meters
Answer B
Answer:
Option B is correct.
Explanation:
Potential energy or chemical potential energy is used to Cook food which is then converted into thermal energy. The type of energy used also depends upon the type of cooking appliances used.
For e.g. stove convert potential energy to thermal energy.
The difference is that nuclear plants do not burn anything. Instead, they use uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission<span>. Nuclear power plants obtain the heat needed to produce steam through a physical process.
Hope this helps :)</span>
