Force is a measure of the interaction between bodies, mass is a measure of the amount of material in an object, weight is the gravitational force acting on a body (although for trading purposes it is taken to mean the same as mass) and load usually means the force exerted on a surface or body
The list of choices you gave us doesn't have any true statements on it.
Answer:
emf = - 0.622 V
Explanation:
The electromotive force is given by Faraday's law
emf =
Ф = B. A
bold indicates vectors
Ф = B A cos θ
in this case it is indicated that the magnetic field is constant and the angle between the magnetic field and the normal to the area is parallel, so the cos 0 = 1
we substitute
emf =
the area of the circle is
A = pi r²
emf = B 2π r
speed is defined
v =
we substitute
emf = - 2π B r v
let's calculate
emf = - 2π 0.5 1.65 π0.12
emf = - 0.622 V
Answer:
yes it was a constant speed and the car traveled 10 meters in 20 seconds.
