Answer: The correct answer is "motor".

Explanation:

Electric motor: It is the device which converts the electrical energy into the mechanical energy.

When the current is flowing through the wire then there will be magnetic field around the wire.

Both magnetic field and the electric field are applied in the motor. So, there will be electric force and the magnetic force.

Electricity can be used to move magnet. The electric motor uses electricity in this way. It generates the magnetic field with the electric current flowing through the coil. This magnetic field helps in moving the magnet that runs the motor.

Therefore, motor is a device which uses an electromagnet to convert electrical energy into mechanical energy.

Answer:

0.625 c

Explanation:

Relative speed of a body may be defined as the speed of one body with respect to some other or the speed of one body in comparison to the speed of second body.

In the context,

The relative speed of body 2 with respect to body 1 can be expressed as :

$u'=\frac{u-v}{1-\frac{uv}{c^2}}$

Speed of rocket 1 with respect to rocket 2 :

$u' = \frac{0.4 c- (-0.3 c)}{1-\frac{(0.4 c)(-0.3 c)}{c^2}}$

$u' = \frac{0.7 c}{1.12}$

$u'=0.625 c$

Therefore, the speed of rocket 1 according to an observer on rocket 2 is 0.625 c

Difference between electrolytes and nonelectrolytes.

Trava [24]

Answer:

Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity. Nonelectrolytes do not dissociate into ions in solution; nonelectrolyte solutions do not, therefore, conduct electricity

The sun produces large amounts of energy. By what process does the sun produce energy?

AlladinOne [14]

The sun produces energy by converting gravitational potential energy into radiation via quantum processes in the nucleus of the atoms.

Since the mass of the sun and it's temperature are not quite enough to generate nuclear FUSION on their own, quantum tunneling is the primary process by which nuclear fusion occurs in our sun, SOL. FISSION also occurs as a result of this fusion.

Additionally, gravitational potential energy is also the reason that supernovae are so bright. Cool!
