(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 …

9. Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .15 seconds. Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.
