If the distance between the sun and the earth is `1.5xx10^(11) m` and velocity of light is `3xx10^(8) m//s`, then the time taken by a light ray to reach the earth from the sun is

The mean distance of sun from the earth is 1.5xx10^8km . The time taken by light to reach earth from the sun is

A physics teacher asked a student to find how much time does the light take to reach the earth if the distance between the sun and the earth is 150xx10^(6)km ? Teacher also gives an extra input that velocity of light is 3xx10^(8)ms^(-1) . What would be the answer of the student?

The distance of a galaxy from the earth is 5.6 xx 10^(25) m. Assuming the speed of light to be 3 xx 10^8 m s^(-1) find the time taken by light to travel this distance.

The distance of a galaxy from the earth is of the order of 10^(25)m . The time taken by light to reach the earth from the galaxy is

The distance of a galaxy from the earth is of the order of 10^(25)m . The time taken by light to reach the earth from the galaxy is

The distance between the sun and the Earth is 1.496xx10^(8) km and distance between the Earth and the Moon is 3.84xx10^(8)m . During solar eclipse the Moon comes in between the Earth and the sun. What is the distance between the Moon and the sun at that particlar time?

The distance of the sun from earth is 1.496xx10^(11)m. If the angular diameter of the sun is 2000'', find the diameter of the sun.

The average distance between the surface of the Earth and the surface of the Sun is 1.49xx10^(11) m. How much time in minutes does it take for light leaving the surface of the Sun to reach the Earth ?
