Since you put your question in the <Physics> category, I'll assume
you're talking about mechanical or electrical power, and not political
or military power etc.

Power is the rate of doing work or moving energy from one place
to another.

In mechanical contraptions, Work is (force) x (distance) ,
so
                           Power = (work) divided by (time)

                               or     = (force) x (distance) divided by (time).

In electrical circuits,

                           Power = (voltage) x (current)

                               or    =  (current)² x (resistance)

                               or    =  (voltage)² divided by (resistance) .

(Just use the formula with whatever quantities you know.)

As it was categorized in the physics category it must be the mechanical power.


Power is basically the amount of work done per unit time or in simpler words the amount of energy transferred per unit time.


The SI unit for power is Watt. Which is basically J/s or Nm/s as wor has the unit of Nm.


In electrical components power can also be categorized as the amount voltage supplied multiplied by the current passed through the component.

How much would you have to eat for your appendix to explode ? I ate so much on thanksgiving and i need to know i’m very scared
dimulka [17.4K]

Answer:

I don't think your appendix can explode because you ate too much honestly. It's not even possible to eat so much that your appendix explodes, and if you're feeling any pain it definitely isn't because your appendix is about to explode, believe me. Also you could just type it into the internet, that'd be a much faster solution.

A package of aluminum foil contains 50. ft2 of foil, which weighs approximately 6.0 oz. Aluminum has a density of 2.70 g/cm3. Wh
SIZIF [17.4K]

Answer:

1.36 x 10^-3 cm

Explanation:

Area = 50 ft^2 = 46451.5 cm^2

mass = 6 oz = 170.097 g

density = 2.70 g/cm^3

Let t be the thickness of foil in cm.

mass = volume x density

mass = area x thickness x density

170.097 = 46451.5 x t x 2.70

t = 1.36 x 10^-3 cm

Thus, the thickness of aluminium foil is 1.36 x 10^-3 cm.

If a cart of a roller coaster has a mass of 250kg and is at a height of 14 meters. What is the cart's potential energy?
ahrayia [7]

Answer:

3430000 J

Explanation:

The formula for potential energy is PE=mgh.

M being the mass, g being the force of gravity, and h being the height.

First thing you want to do is convert 250 kg to g (grams).

From there you get 25000g and you have to multiply that by 14m and 9.8m/s^2 (the force of gravity is constant, at least on earth).
