Physics
1 answer:
Semenov [28]3 years ago

For this case we have that by definition, physical power refers to the amount of work done for a unit of time.

So:

P = \frac {W} {t}

Where:

W: It's the work

t: It's time

The power units are in \frac {Joules} {s} = Watts

So, according to the problem data we have:

P = 100W\\t = 120s

Clearing the work of the formula:

W = P * t\\W = 100 * 120 = 1200

Thus, the work is 1200 joules.

Answer:

Option C

Density of Earth: 5.514 g/cm³
Density of Jupiter: <span>1.326 g/cm³

1.326 g/cm³ / 5.514 g/cm³ </span>≈ <span>0,24
0,24 * 100 = 24%

Jupiter has 24% of earth's density.

A student made the claim that a 4 gram paintball fired from a paintball gun at 90 m/s could have about the same kinetic energy a
vovikov84 [41]

This question involves the concept of kinetic energy.

The student's claim is "right".

<h3>Kinetic Energy</h3>

The energy possessed by a body, by the virtue of its motion is called kinetic energy. Mathematically it is given by the following formula:

K.E =\frac{1}{2}mv^2

where,

  • K.E = Kinetic energy
  • m = mass
  • v = velocity

Therefore,

For the paintball:

K.E = \frac{1}{2}(4\ g)(90\ m/s)^2

K.E = 16200 J

For the pellet:

K.E = \frac{1}{2}(1\ g)(180\ m/s)^2

K.E = 16200 J

Hence, both paintball and pellet will have same kinetic energy. The student is right.
