Clouds gather and get full of rain. The rain is too much for the cloud then it falls down as precipitation

1hp is written in electric motor what does it mean

Angelina_Jolie [31]

Explanation:

The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).

imagine that you are on a spaceship that is far from the sun or any planet. Explain why a 500 kg piece of equipment would be dif

Mila [183]

Even though the object is weightless, it would need inertia, I.e, you pushing it or any form of transportation. So you would still have to push that 500kg to just keep it moving in space. Say if it were a planet with less gravitational force, it would be weightless.

Describe how a unique position of the sun , earth, and moon creates a lunar eclipse

Serggg [28]

A eclipse of the sun can only occur at a new moon when the moon passes between earth and sun. If the moons shadow happens to fall upon earths surface at a time, you'll see some portion of the suns disk covered or aka eclipsed by the moon.. I hope that helps

How are magnetic forces like electric forces? (4 points) Select one: a. They both have charges b. In both, opposites attract. c.

nlexa [21]

Lets take it down a notch and break it down:

Magnetic forces and electric forces are quite similar, lets take a look at the answers possible:

A. They both have charges

False, magnetic forces do not HAVE charges, but they have an EFFECT on moving charges (that are creating a magnetic field around them).

Why? Electrical forces have positive and negative charges while magnetic forces have a north and south POLE. These two are different forces, therefore magnetic forces do not HAVE charges.

B. In both, opposites attract

We all know opposite poles attract, like poles, don't attract (repelling force). This is true for the magnetic force, now, the electric force, two positively charged particles will exert a repulsive force on one another. DING DING. We have a winner. B is TRUE.

C. In both, opposites repel

False, we already know in electric and magnetic forces that opposites attract and similar charges/poles repel.

D. Neither have charges

False, this is a joke question right? Don't even look at this one!!!!!!!!!

Therefore, B, is the only true answer that describes how magnetic and electric forces are similar.

Have a nice day!
