The earth takes almost ………….. days to revolve around the Sun.
The earth takes 24h to rotate once about its axis. How much time does the sun take to shift by 1^(@) when viewed from the earth ?
A sphere is rotating about a diameter
Calculate the ratio of the angular momentum of the earth about its axis due to its spinning motion to that about the sun due to its orbital motion. Radius of the earth =6400 km and radius of the orbit of the earth about the sun =1.5xx10^8km.
Find the acceleration of a particle placed on the surface of the earth at the equator due to earth's rotation. The diameter of earth =12800 km and it takes 24 hour for the earth to complete one revolution about its axis.
If the Earth stops rotating about its axis, then by what value will the acceleration due to gravity change at the equator?
The moon takes about 27.3 days to revolve around the earth in a nearly circular orbit of radius 3.84xx10^5 km . Calculate the mass of the earth from these data.
Equal torques are applied on a cylinder and a sphere. Both have same mass and radius rotates about its axis and sphere rotates about one of its diameter. Which will rotates acquire greater speed and why?
