One coulomb of charge has the equivalent charge of 6.25x10^18 electrons. This is determined from the value of charge on one electron and the value of charge for 1 coulomb
Answer:
Explanation:
Given
mass of body
radius of circle
Time Period
suppose is the angular velocity of revolution
therefore
Centripetal acceleration
therefore centripetal
The negative charges and positive charges in the wire are pushed in the opposite directions by the magnetic field
Answer:
Nothing
Explanation:
The radius of the orbit of the Earth does not depend on the radius of the sun.
In fact, the gravitational attraction between the Earth and the Sun provides the centripetal force that keeps the Earth in orbit:
where
G is the gravitational constant
M is the mass of the sun
m is the mass of the Earth
r is the radius of the orbit of the Earth
v is the orbital speed of the earth
Re-arranging the equation for r:
Also,
where is the angular velocity of the Earth's orbit. So we can rewrite the equation as
As we see, the radius of the orbit of the Earth, r, does not depend on the mass of the Sun, so if the sun shrank in size, the orbit remains the same.
The object will burn as it passes the atmosphere thus reducing the size and the impact of the object
