As the earth rotates about its axis, a person living in his house at the equator goes in a circular orbit of radius equal to the radius of the earth. Why does he/she not feel weightless as a satellite passenger does?

One projectile after deviating from its path starts moving round the earth in a circular path of radius equal to nine times the radius of earth R. Its time period is

A satellite is moving around the earth's with speed v in a circular orbit of radius r . If the orbit radius is decreases by 1% , its speed will

A satellite of mass m goes round the earth along a circular path of radius r. Let m_(E) be the mass of the earth and R_(E) its radius then the linear speed of the satellite depends on.

A satellite of mass m is in an elliptical orbit around the earth of mass M(M gt gt m) the speed of the satellite at its nearest point ot the earth (perigee) is sqrt((6GM)/(5R)) where R= its closest distance to the earth it is desired to transfer this satellite into a circular orbit around the earth of radius equal its largest distance from the earth. Find the increase in its speed to be imparted at the apogee (farthest point on the elliptical orbit).

A remote sensing satellite is revolving in an orbit of radius x on the equator of earth. Find the area on earth surface in which satellite can not send messsage.

If the speed of rotation of earth about its axis increases, then the weight of the body at the equator will

The mean radius of earth is R, its angular speed on its own axis is w and the acceleration due to gravity at earth's surface is g. What will be the radius of the orbit of a geostationary satellite

Assertion : If the earth stops rotating about its axis, the value of the weight of the body at equator will decrease. Reason : The centripetal force does not act on the body at the equator.

A 400 kg satellite is in a circular orbit of radius 2 R_(E) about the Earth. How much energy is required to transfer it to a circular orbit of radius 4R_(E) ? What are the changes in the kinetic and potential energies ?

The earth takes 24 h to rotate once about its axis. How much time does the sun take to shift by IS when viewed from the earth ?
