What is the energy equivalent of an object with a mass of 25 kg?

Physics
1 answer:
Amanda [17]3 years ago
3 0

Answer:

2.25\cdot 10^{18} J

Explanation:

The energy equivalent of the mass of an object can be calculated by using the Einstein's equation:

E=mc^2

where

E is the energy

m is the rest mass of the object

c=3\cdot 10^8 m/s is the speed of light

For this object

m = 25 kg

So its equivalent energy is:

E=(25)(3\cdot 10^8)^2=2.25\cdot 10^{18} J

What causes clouds of dust and gas to form a protostar
just olya [345]
<h2>Answer: Gravitational attraction </h2>

Gravity force causes the clouds of dust and gas to form a protostar. As this <u>attraction force</u> is responsible for gathering and compressing the existing elements in the cloud of gas and dust, heating them during this process.

Then, when the amount of material accumulated by gravitational contraction is large enough, and the temperature and pressure reached high enough, the <u>nuclear fusion</u> process will begin.

To understand it better: The hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.

It should be noted that the protostars radiate half of the energy contributed by the gravitational collapse and the other half is invested in heating its core.
