Answer:
fem = -0.126 V
Explanation:
Faraday's law is
fem = 
where the flow is
Ф = B . A = B A cos θ
bold letters indicate vectors.
In this case, the normal to the area is parallel to the magnetic field, so the angle is zero and the cos0 = 1
fem = 
in this case they indicate that to carry the loop from outside to inside the field in Δt = 5 s, so we can change them by variations
fem = 
let's calculate
fem = - 0.7 (0.9 -0) / 5
fem = -0.126 V
Answer:
Explanation:
Given,
Magnetic field,B = 0.5 x 10⁻⁴ T
distance,r= 15 cm = 0.15 m
Current = ?
Using Ampere's law of magnetic field
Current in the wire is equal to
If I remember correctly, it is a state an object is in when no force is acting on it or when there is equal amount of force in each direction is being applied to it. Basically, either the object is motionless or is traveling at a constant velocity, there is no acceleration.
Explanation:
Newton’s third law of motion states that every action has an equal and opposite reaction. This indicates that forces always act in pairs. Reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don’t cancel each other out.
