The answer is; E
The key word is photochemical smog that differentiated it from industrial smog that are formed from different conditions. Photochemical smog is majorly driven by the sun that splits nitrogen oxide pollutants in the air into nitrogen and oxygen. The oxygen forms OH radicals with the water vapour in the air. The OH forms radicals with hydrocarbons pollutants in the air which ultimately form aldehyde peroxides that are a health risk.
It is True.
<h3>What system removes and reduces heat caused by friction?</h3>
A mechanical brake applies a friction force to convert the kinetic energy of the vehicle into thermal energy which then dissipates into the atmosphere. Braking systems which don't use friction are referred to as regenerative braking systems (RBSs).
Slowing down is the most common way of controlling the speed of an article by restraining its movement. An item moving has motor energy and to halt the article this active energy should be taken out.
Eliminating the dynamic energy can be achieved by dispersing the energy to the air through grinding or by changing over it into one more type of energy. The most well-known sort of slowing down is a mechanical brake which hinders movement through rubbing brake cushions. A mechanical brake applies a grating power to change over the motor energy of the vehicle into nuclear power which then, at that point, disperses into the atmosphere.
Braking frameworks which don't utilize grinding are alluded to as regenerative slowing mechanisms (RBSs). In RBSs, the active energy is changed over into different types of valuable energy, which can be put away for sometime in the future, expanding eco-friendliness.

An upwards acceleration of the elevator would cause this greater reading since the scale displays the Normal Force of the object on it. The inertia of the person would prefer to stay stationary, so the scale must push up on the person to accelerate him upward along with the elevator. This results in the following equation:
W = mg + ma
Where mg represents the weight reading without external acceleration and ma as the weight reading due to the external acceleration.
Answer:
0.17 degrees
Explanation:
From the question we are given the following:
acceleration due to gravity = 
radius (r) = 6.5 cm = 0.065 m
time (s) = 9.3 s
angle = ?
- we first have to calculate the distance the water moves, and this is the circumference of the microwave
circumference = 2 x π x r = 2 x π x 0.065 = 0.408 m
- Now we find the speed with which it moves at
speed = 
= 
= 0.044
- The next step is to find the centripetal acceleration
a = 
= 
= 0.03
being a vector quantity, acceleration has direction, the centripetal acceleration is the x component while the y component would be the acceleration due to gravity (g)
A = 0.03 x + 9.8 y
to find the angle we can apply tan θ = 
θ = 0.17 degrees
