A radar signal is beamed towards a planet and its echo is recived 7 minutes later. If the distance between the planet and earth is `6.3xx10^(10)m,` calculate the speed of the signal.

A RADAR signal is beamed towards a planet and its echo is received 7 minutes later. If the distance between the planet and the Earth is 6.3 xx 10^(10) m. Calculate the speed of the signal.

A rada signal is sent towards a planet and its echo is received after 600 seconds. Find the distance of the planet from the earth.

A radar signal is beamed towards a planet from the earth and its echo is received seven minutes later. Calculate the velocity of the signal, if the distance between the planet and the earth is 6.

The mass of a planet is 1/25 th of the mass of the earth. The distance between the planet and the earth is 6xx 10^8 m. At what distance from the earth, the gravity becomes zero

The mass of the earth is 6 × 10^(24) kg and that of the moon is 7.4 xx 10^(22) kg. If the distance between the earth and the moon is 3.84xx10^(5) km, calculate the force exerted by the earth on the moon. (Take G = 6.7 xx 10^(–11) N m^(2) kg^(-2) )
