When it rains, dust particles and oil residues float on the water and this reduces the traction of tires.
<h3>What
is traction?</h3>
This concept refers to a force between the tires and road that causes the movement of the wheels or vehicle is slower.
<h3>What happens with traction when it rains?</h3>
It is well-known more accidents occur when it rains, which is caused by cars slidding on the road. This is because when it rains traction or the grip of the wheel drastically reduces.

Big bang happened about 13.7 billion years ago in our universe.
<h3>
Describe the beginning of the universe according to the big bang theory?</h3>
According to the big bang theory, about 13.7 billion years ago, an explosive expansion began, expanding our universe outwards faster than the speed of light.
<h3>Describe the future of the universe according to the flat model?</h3>
According to the flat model, the universe is infinite and will continue to expand forever because the universe is expanding.
<h3>What is cosmic background radiation? </h3>
Cosmic background radiation is a weak radio-frequency radiation that is traveling through outer space in every direction. It is the residual radiation of the big bang, when the universe was very hot.
<h3>How do observations of the cosmic background radiation provide evidence to support the big bang theory? </h3>
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe has all over radiation which is called the “cosmic microwave background".

Answer:
or 
23.4843749996 m
Yes
Explanation:
E = Electric field = 
c = Speed of light = 
m = Mass of proton= 
q = Charge of electron = 
Acceleration is given by

Dividing by g

The acceleration is
or 

The distance is 23.4843749996 m
The gravitational field is very small compared to the electric field so the effects of gravity can be ignored.
Answer: N = Mgcos(theta)
Therefore, the Normal reaction force is equal to Mgcos(theta)
Explanation:
See attached for a sketch.
From the attachment.
.
N = normal reaction force on block
W = weight of the block
theta = angle of the inclined plane to the horizontal
From the sketch, we can see that
N is equal in magnitude but opposite direction to Wy
N = Wy
And
Wy = Wcos(theta)
Wx = Wsin(theta)
Then,
N = Wy = Wcos(theta)
But W = mass × acceleration due to gravity = mg
N = Mgcos(theta)
Therefore, the Normal reaction force is equal to Mgcos(theta)
