Answer:

(C). The line integral of the magnetic field around a closed loop

Explanation:

Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux.

This can be written mathematically as;

EMF = -\frac{\delta \phi _B}{\delta t}

(\frac{\delta \phi _B}{\delta t} ) is the rate of change of the magnetic flux through a surface bounded by the loop.

ΔФ = BA

where;

ΔФ is change in flux

B is the magnetic field

A is the area of the loop

Thus, according to Faraday's law of electric generators

∫BdL = \frac{\delta \phi _B}{\delta t} = EMF

Therefore, the line integral of the magnetic field around a closed loop is equal to the negative of the rate of change of the magnetic flux through the area enclosed by the loop.

The correct option is "C"

(C). The line integral of the magnetic field around a closed loop

The earth exerts a gravitational force of 500 N on Amy. What is Amy’s mass in kg?
White raven [17]

Gravitational force of earth is given as weight of object

so here we know that gravitational force on Amy is 500 N

so we will have

mg = 500 N

now we will have

g = 9.8 m/s^2

now from above equation we will have

m (9.8 m/s^2) = 500 N

m = \frac{500}{9.8} kg

m = 51 kg

so the mass of the Amy is 51 kg

An example of vector quantity thats not a force
Nataliya [291]
Examples of such quantities include distance, displacement, speed, velocity, acceleration, force, mass, momentum, energy, work, power, etc. All these quantities can by divided into two categories - vectors and scalars. A vector quantity is a quantity that is fully described by both magnitude and direction.
