Answer:

Student A is correct.

Explanation:

An electromagnet can be defined as the magnet that is produced by the electric current passing through a wire surrounding a metal piece. In an  electric motor, magnets surrounds the the coil carrying currents. Because of the magnetic field, the current carrying coil experiences a force and it starts to rotate. Thus the electric motors uses the forces between the electromagnets to start running.

Therefore, student A is correct.

Vikki [24]

Answer:

200 m/s

Explanation:

Given that,

A plane is moving due north, directly towards its destination. Its airspeed is 200 mph. A constant breeze is blowing from west to east at 60 mph.

We need to find the rate at which the plane is moving towards North. It can be given by :

V_x=v\cos\theta

Where

\theta is the angle with the North

V_x=200\times \cos(\dfrac{60}{200})\\\\=199.99\ m/s\\\\\approx 200\ m/s

Hence, the plane is moving at a rate of 200 m/s.

krek1111 [17]

Answer:

Explanation: In DC circuit, the current will flow for a short time, which is required to charge the capacitor. Once you switch it on, it spikes and the gradually decreases to almost zero (0) as the capacitor becomes fully charged.

In an AC circuit, the circuit acts as if the current is flowing throw the plates whereas is not actually flowing. The circuit acts like the AC is flowing through the capacitor.
