Suppose Earth’s orbital motion around the Sun is suddenly stopped. What time will the Earth take to fall into the Sun?

Asnwer true or false The motion of moon around the earth is circular

An artificial satellite revolves around the earth in circular orbit of radius r with time period T . The satellite is made to stop in the orbit which makes it fall onto the earth. Time of fall of the satellite onto the earth is given by

Ram and Shyam are two students of ACME couse. One day after the test, they start discussing about the motion of the moon around the earth. The moon is known to take 27 days in competing a circular orbit. In the figure, the moon moves counterclockwise (ABCD) around the earth. Ram asks Shyam : "What is the direction of the impulse of gravitational force due to earth on moon for one half of an orbit, starting at C and ending at A"?

An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of escape velocity from the earth. (i) Determine the height of the satellite above the earth's surface. (ii) If the satellite is stopped suddenly in its orbit and allowed to fall freely onto the earth, find the speed with which it hits the surface of the earth.

The sketches show the phases of the Moon one week apart. The diagram shows the Moon's orbit around the Earth. Use the diagram and the sketches to answer the questions below: How much of the sunlit part of the Moon was visible from Earth on March 8?

The angle subtended by the moon's diameter at a point on the earth is about 0.50^(@) . Use this and the fact that the moon is about 384000km away to find the approximate diameter of the moon .
