A 4400 W motor is used to do work. If the motor is used for 200 s, how much work could it do? (Power: P = W/t)
guajiro [1.7K]
So if p=w/t
then 4400=(w)(200)
so you would multiply 4440•200 and get 880,000

An object with a density of 250 kg/m3 floats on water. what portion of the object is submerged?
lbvjy [14]

The portion of the object submerged in water is determined as 0.25.

<h3>Fraction of the object submerged in water</h3>

The fraction of the object submerged in water is calculated as follows;

S.G =  (density of object) / (density of water)

where;

  • S.G is specific gravity

S.G = (250 kgm⁻³) / (1000 kgm⁻³)

S.G = 0.25 = ¹/₄

Thus, the portion of the object submerged in water is determined as 0.25.

Plssss help quick <br>Why does a fast moving person feel heavier than normal? ​
vovangra [49]

Answer:

So, if you move faster, and as you move faster, you generate more Electromagnetic Energy, then as you move faster, you push more Dark Energy away from yourself! And Dark Energy pushes harder against you, so you get heavier! So, if you move FAST, your time slows down!
