<span>A motor produces less mechanical energy than the energy it uses because the motor looses some energy to heat.</span>
Answer:
a)
m/s
b)
Angular frequency = 
Explanation:
As we know
q is the charge on the electron = 
C
B is the magnetic field in Tesla = 
T
r is the radius of the circle = 
m
mass of the electrons = 
Kg
a)
Substituting the given values in above equation, we get -
m/s
b)
Angular frequency =
<span>"The direction of motion is caused by the Coriolis effect. This can be ... storms in the Northern Hemisphere, but rotate clockwise in the <span>Southern Hemisphere</span></span>
<span>As it is uniform circular motion therefore speed is constant. Therefore we can rule out option B. Also in circular motion the direction of velocity vector changes therefore velocity can't be constant. Therefore option B is incorrect as well. Also centripetal acceleration is always towards the center so option D is wrong as well.
That implies
option A is correct.</span>
Answer:
microscopic means that they are very very tiny, you cannot see them with the human eye, you have to use a tool like a microscope
