I need a equation for a problem in using a pulling force a mass a coefficient of static friction a coefficient of kinetic friction and solving for the frictional force

Answers

Answer 1
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'.

A physical science test book has a mass of 2.2 kg what is the weight on mars??? please help

Answers

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

Test Book's weight on mars = 8.1 N.

What is different between mass and weight?

  • 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 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 _____ and _____ sphere interaction.biosphere, lithosphere; biosphere, atmosphere; hydrosphere, lithosphere; or cryosphere, lithosphere biosphere, lithosphere biosphere, atmosphere hydrosphere, lithosphere cryosphere, lithosphere

Answers

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.

Explain what happens when you vigorously rub your wool socks on a carpeted floor,touch a metal doorknob and get shocked

Answers

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.

Final answer:

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.

Explanation:

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.

A 4kg block sitting on the floor, how much potential energy does it have?

Answers


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 relative to some place.  It's the work you have to do
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 (height) .

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
