Use the Heat formula for both problems.
q=m*c*∆t
Where
q= heat in Joules
m= mass in grams
c= specific heat which is a constant 4.18
∆t= change in temperature
Thermal energy is THE MEASURE OF TEMPERATURE IN A SYSTEM.
Thermal energy refers to the internal energy that is present in a system as a result of its temperature. The motion of the particles of an object depends on the temperature of the object and the higher the temperature, the faster the movement of the particles. The reverse is also true.
<u>Out of all given options, Hubble's findings supported the big bang theory are as follows:
</u>
- The universe formed from a central point.
- Most galaxies in the universe are moving away from Earth.
- There are billions of galaxies in the universe, not just one.
Option C, D, and E
<u>Explanation:
</u>
According to big bang theory, the universe is increasing its region of occupancy in free space. As it is known that the universe is composed of several galaxies. So this spreading of the universe is nothing but spreading of galaxies.
And this is confirmed from Hubble’s findings using Hubble’s telescope. As they have observed that the speed at which the galaxies are travelling in free space has been increased at a faster rate.
So, the galaxies are used to move away from Earth with time at a faster rate which confirms the big bang theory of universe formation. Also, in simple words, universe started from big bang according to cosmology' standard theory, it’s just moves from everything else.
