(a) Explanation Given Info: The energy emitted by the sun is 3.8 × 10 26 W . The formula to calculate total energy emitted is, E = m c 2 Rewrite the above equation in terms of m is given by, m = E c 2 m is matter converted by the sun through emission per second c is the velocity of light with value 3 × 10 8 m ⋅ s -1 Substitute 3.8 × 10 26 W for E, 3 × 10 8 m ⋅ s -1 for c , in the above equation to find m , m = 3.8 × 10 26 W ( 3 × 10 8 m ⋅ s -1 ) 2 = 3.8 × 10 26 ( J ⋅ s − 1 ) ( 3 × 10 8 m ⋅ s -1 ) 2 = 4 (b) To determine The time required by the sun to take its whole mass.

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience …

On Dec 5, 2022, scientific history was made at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California when nuclear fusion was achieved when the 192 lasers deposited about 2 Megajoules (MJ) of energy into a frozen pea sized deuterium-tritium pellet and ignited the pellet through nuclear fusion to release 3 MJ of energy. The metric prefix mega means million (10^6). a) How much mass (kg) would be required to release 1 MJ of energy?

A unique star produces energy by nuclear fusion reactions, in which matter is converted into energy. By measuring the amount of energy we receive from that star, we know that it is producing energy at a rate of 4.8 x 10 26 How many kilograms of matter does this star lose each second?

The sun produces energy by nuclear fusion reactions, in which matter is converted into energy. By measuring the amount of energy we receive from the sun, we know that it is producing energy at a rate of 3.8 * 1026 W. (a) How many kilograms of matter does the sun lose each second? Approximately how many tons of matter is this (1 ton = 2000 lb)? (b) At this rate, how long would it take the sun to use up all its mass?
