Let's fill in the gaps.
Distance between earth and moon is 384, 000,000 m.
`= 384 xx 10^?m.`

Mass of the earth is 81 times has mass of the moon. The distance between earth and moon is 4xx10^5 km. calculate the position of the point on the line joining the centres of earth and moon where the gravitational field is zero.

The moon revolves around the earth once in 271/3 days. If the average distance between the earth and moon is 384000km , determine the orbital speed and the orbital angular velocity of the moon.

Let's fill in the blank squares given below:- 10^2 = ?xx ?

In Young’s double slit experiment the distance between two slits is 0.3 xx 10^-3 m, the distance betwe'en slits and screen is 1.2 m. Distance of second bright fringe from the centre of the central bright fringe is 4.5 xx 10^-3 m. Obtain wavelength of the ligth .

In Young’s double slit experiment the distance between two slits is 0.3 xx 10^-3 m, the distance betwe'en slits and screen is 1.2 m. Distance of second bright fringe from the centre of the central bright fringe is 4.5 xx 10^-3 m. Obtain fringe width.

Two rods of 13m length and 7m length are situated perpendicularly on the ground and the distance between their foots is 8m.The distance between their top parts is

A man running on a race course notes that the sum of his distances from the two flag posts is always 10 m and the distance between the flag posts is 8 m. Find the equation of the path traced by the man.

The average distance of the sun from the earth is 1.5xx10^8 km and the average distance of the moon from the earth is 384000 km. if the attraction of the sun on the earth is 180 times the attraction of the moon ,how many times is the mass of the sun greater than that of the moon ?

Two pillars of lengths 6m and 11m stands up vertically with the ground. If the distance between their foots be 12m,then find the distance between their vertices.

A monochromatic light of wavelength 600 nm is emitted from slit of thickness 1 mm. if the distance between the slit and the screen is 2m. Then calculate the gap between the two adjacent first maximum points of the central maximum.
