What is the energy equivalent of an object with a mass of 2.5 kg? 5.5 × 108 J 7.5 × 108 J 3.6 × 1016 J 2.25 × 1017 J

We can use the Einsten's relation which states the equivalence between mass and energy:
$E=mc^2$
where
E is the energy
m is the rest mass of the object
c is the speed of light

By using this formula and m=2.5 kg, we can find the equivalent energy of the object:
$E=mc^2 = (2.5 kg)(3 \cdot 10^8 m/s)^2=2.25 \cdot 10^{17} J$

Which of the following statements is/are true? Check all that apply. Check all that apply. Power is the rate at which energy is

AlladinOne [14]

Answer:

True statements:

Power is the rate at which work is done.

Power is the rate at which energy is transformed.

The SI unit of power is watt.

A person is limited in the total work he or she can do by the rate at which energy can be transformed.

Explanation:

The above statements are true.

1. Power is defined as the rate at which work is done.

2. Power is the rate at which energy is transformed. Whenever energy changes its form, or moves from one place to another, the rate at which it makes those changes is described as power.

3. The SI Unit of power is watts. If 1 joule of energy is converted by an object in 1 second then its power is called one watt.

So, the statement 'the SI unit of power is the horsepower' is false.

4. A person is limited in the total work he or she can do by the rate at which energy can be transformed i.e, his power. He is not only limited by the total energy required.

So, the statement 'A person is limited in the total work he or she can do only by the total energy required' is not completely true.
