Answer:
Because the Sun shines by nuclear fusion, which converts mass into energy as hydrogen turns into helium. ... A typical star that is the source of light and heat for the planets in the solar system.
Explanation:
Density = Mass per unit Volume
that is,
D = m / V
Now,
We've been provided with,
Density = 790 kg/m³
Volume = 1250 litres = 1.250 m³
Now,
![density = \frac{mass}{volume} \\ 790 = \frac{m}{1.250} \\ 790 \times 1.250 = m \\ m = 790 \times 1.250 \\ m = 790 \times \frac{1250}{1000} \\ m = 790 \times \frac{5}{4} \\ m = 197.5 \times 5 \\ m = \frac{1975}{10} \times 5 \\ m = \frac{1975}{2} = 987.5 \: kg](https://tex.z-dn.net/?f=density%20%3D%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C%20790%20%3D%20%5Cfrac%7Bm%7D%7B1.250%7D%20%5C%5C%20790%20%5Ctimes%201.250%20%3D%20m%20%5C%5C%20m%20%3D%20790%20%5Ctimes%201.250%20%5C%5C%20m%20%3D%20790%20%5Ctimes%20%5Cfrac%7B1250%7D%7B1000%7D%20%5C%5C%20m%20%3D%20790%20%5Ctimes%20%5Cfrac%7B5%7D%7B4%7D%20%5C%5C%20m%20%3D%20197.5%20%5Ctimes%205%20%5C%5C%20m%20%3D%20%5Cfrac%7B1975%7D%7B10%7D%20%5Ctimes%205%20%5C%5C%20m%20%3D%20%5Cfrac%7B1975%7D%7B2%7D%20%3D%20987.5%20%5C%3A%20kg)
987.5 kg of mass will a 1250 litres tank will hold.

the car travels 34 mi in one hour.
then, in 6 hours car travels
34 x 6 mi
= 204 mi
The Sun gives off energy, and that energy can be found deep in it's core, the Sun is busily converting mass into energy. According to Einstein equation of mass and energy equivalence, from his very famous equation E = mc².
Given: Energy E = 3.6 X 10²⁶ J
Speed of light c = 3.00 x 10⁸ m/s
Required: Mass m loss by the sun each second
Formula: E = mc² derive for mass m
m = E/c²
m = 3.6 x 10²⁶ Kg.m²/s² or J/(3.00 X 10⁸ m/s)²
m = 4 x 10⁹ Kg or the Sun is loosing
m = 4 million tons of mass each second
