Answer:
The minimum pulling force required to start it moving is

equal to the static frictional force.

F = (mass) x (gravity) x (coefficient of static friction).

Once it's moving, the force required to keep it moving at a steady speed,

without speeding up or slowing down, is the force of kinetic friction.

F = (mass) x (gravity) x (coefficient of kinetic friction).

In both equations, [ (mass) x (gravity)] is just the object's 'weight'.

-infrared light

-microwaves

-gamma rays

-visible light

-X-rays

On this list, 'gamma-'s and 'X-'s are the ones.

its gamma rays and x-rays they are the only two out of my knowledge.

**Weight** is defined as a body's **mass** multiplied by its acceleration due to gravity.

Test Book's weight on mars = 8.1 N.

- The distinction between
**Mass**and Weight is Weight is a measure of force, while**mass**is a measure of inertia. Many people use these two terms interchangeably. - The
**mass**of a body is the amount of matter contained within it, whereas the weight of a body is the force acting on it as a result of gravity's acceleration. In chemistry, this is the primary distinction between**mass**and weight. - Weight is defined as a body's
**mass**multiplied by its acceleration due to gravity.

Weight = (**mass)** x (gravity)

= (2.2 kg) x (3.7 m/s^2)

= 8.1 newtons

The correct answer for the question that is being presented above is this one: "biosphere, atmosphere." The earth's four main spheres continuously interact to support life and balance Earth's materials. When plants absorb carbon dioxide for photosynthesis, it is an example of biosphere and atmosphere sphere interaction.

**Its "biosphere and atmosphere" because photosynthesis comes from the plants and the atmosphere then consumes the carbon.**

When you are rubbing the wool socks on the carpet, you are transferring electrons. When you touch the metal doorknobs, the electron levels are then going back to normal. The rush of electrons causes the shock.

When you rub your wool socks on a carpeted floor and then touch a metal doorknob, you get shocked. This happens due to the transfer of electrons from the carpet to the socks, resulting in a buildup of negative charge which is discharged when you touch the grounded doorknob.

When you vigorously rub your wool socks on a carpeted floor, you transfer electrons from the carpet to the socks through friction. This creates a buildup of negative charge on the socks. When you then touch a metal doorknob, which is grounded, the excess electrons on your socks quickly flow to the doorknob, resulting in a sudden discharge of static electricity and a shock.

Well, there you have a very important principle wrapped up in that question.

There's actually no such thing as a real, actual amount of potential energy.

There's only potential

to lift the object from that reference place to wherever it is now. It's also

the kinetic energy the object would have if it fell down to the reference place

from where it is now.

Here's the formula for potential energy: PE = (mass) x (gravity) x (

So naturally, when you use that formula, you need to decide "height above what ?"

If you're reading a book while you're flying in a passenger jet, the book's PE is

(M x G x 0 meters) relative to your lap, (M x G x 1 meter) relative to the floor of the

plane, (M x G x 10,000 meters) relative to the ground, and maybe (M x G x 25,000 meters)

relative to the bottom of the ocean.

Let's say that gravity is 9.8 m/s² .

Then a 4kg block sitting on the floor has (39.2 x 0 meters) PE relative to the floor

it's sitting on, also (39.2 x 3 meters) relative to the floor that's one floor downstairs,

also (39.2 x 30 meters) relative to 10 floors downstairs, and if it's on the top floor of

the Amoco/Aon Center in Chicago, maybe (39.2 x 345 meters) relative to the floor

in the coffee shop that's off the lobby on the ground floor.

P.E.=mgh

P.E.= mass×gravity×height, therefore 4kg×10×0= 0 J

K.E. is also equal to 0 because the block is not moving, is in the state of Inertia

P.E.= mass×gravity×height, therefore 4kg×10×0= 0 J

K.E. is also equal to 0 because the block is not moving, is in the state of Inertia
