Galileo was punished by the Church for teaching that the sum is stationary and the earth moves around it. His opponents held the view that the earth is stationary and the sun moves around it. If the absolute motion has no meaing,are the two view points not equally correct or equally wrong?

A satellite moves in a circle around the earth. The radius of this circle is equal to one half of the radius of the moon's orbit. The satellite completes one revolution is :

A satellite moves in a circle around the earth. The radius of this circle is equal to one half of the radius of the moon's orbit. The satellite completes one revolution is :

The force between two points charges +q and -q, separated by a distance r is F. if one charge remains stationary while the other moves around it in a circle of radius r, then the work done is given by

A satellite is revolving around the earth in a circular orbit in a plane containing earth's axis of rotation. if the angular speed of satellite is equal to that of earth, find the time it takes to move from a point above north pole to a point above the equator.

An artificial satellite is moving in an orbit around the earth with a velocity equal to one-third the escape velocity from the surface of the earth. (i) Find the height of the satellite from the surface of the earth.

A satellite moves in a circle around the Earth, the radius of this circle is equal to one half of the radius of the Moon's orbit. The satellite completes one revolution in ........ lunar month.

In the following items, cach passage consists of six sentences. The first sentence (S_1) and the final scntence (S_6) are given in the beginning. The middle four sentences in each have been removed and jumbled up. These are labelled P, Q, R and S. You are required to find out the proper sequence of the four sentences and mark accordingly on the Answer Sheet. S_1 : When Galileo was young, people believed that the earth was the centre of the Universe. S_6 : But time has proved that Galileo's view was right. P: But Galileo began to argue that it was not so. Q: This belief was supported by the State and the Church. R: He said that the Earth and other planets moved round the sun. S: He was imprisoned for voicing this unorthodox view. The proper sequence should be

In Rutherford's nuclear model of the atom, the nucleus (radius about 10^(-15)m ) is analogous to the sum about which the electron moves in orbit (radius about 10^(-10)m ) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom, would the earth be closer to or further away form the sun than actually it is ? The radius of earth's orbit is about is 1.5xx10^(11)m . The radius of the sun is taken as 7xx10^8m .

. In which of the following cases of motions, the distance moved and the magnitude of the displacement are equal? i. If the car is moving on a straight road ii. If the car is moving in circular path iii. The pendulum is moving to and fro iv. The earth is moving around the sun
