A device that uses electricity and magnetism to create motion is called a "Motor" (which converts electric energy into mechanical energy) & <span>In a reverse process, a device that uses motion and magnetism can be used to create "Electromagnetism".

In short, 1st Blank = Motor
2nd Blank = Electromagnetism 

Hope this helps!</span>

Answer:

1. motor

2. electricity

Explanation:

A motor uses electromagnetism or electricity and magnetism to create motion. A motor converts electric energy into mechanical energy.

On the other hand, the reverse process of using motion and magnetism will create electricty. It will convert the mechanical energy to electrical energy. And the machine that does it is called a generator.

how much horse power is needed to move a box that has a force of 1,492 newtons a distance of 2 meters in 1 second
stellarik [79]

This one is a piece 'o cake if you know the definition
of a horsepower, and impossible if you don't.

It is:            1 horsepower = 746 watts

Also, remember that  1 watt = 1 joule/second
                
Now:            Work = (force) x (distance)

To move this box 2 meters,

                     Work = (1,492 newtons) x (2 meters) = 2,984 joules

If you accomplished that feat in 1 second,
then you produced power of

                               (2,984 / 1) (joule/second) = 2,984 watts . 

                             (2,984 watt) x (1 HP / 746 watt) = 4 horsepower .

That's the solution, applying bullet-proof math and physics to the
given data.  But in the real world, I guarantee that you didn't do that.
______________________________________

By the way ... a comment regarding the terminology in the question:

The box doesn't "have a force" of 1,492 newtons.  That's the force
with which you ... or a horse, or an ox ... pushed against the box
in order to move it.

(And, if I might observe, that force is about 336 pounds,
so my money would be on the horse or the ox.)

What is the dimensional formula of thermal conductivity?​
Inga [223]

Answer:

The dimension of thermal conductivity is M1L1T−3Θ−1, expressed in terms of the dimensions mass (M), length (L), time (T), and temperature (Θ). Other units which are closely related to the thermal conductivity are in common use in the construction and textile industries.

In complete sentences, describe what causes the phases of the moon.
s344n2d4d5 [400]
The revolution of the moon going around earth is what causes the phases of the moon. It depends on exactly what point the moon is facing the earth and how much light is being produced onto it that causes the different phases!
