When earth moves round the sun, the quantity which remains constant is:
1 angular velocity
2 kinetic energy
3 potential energy
4 areal velocity
Explanation:
D When earth moves round the sun then according to Kepler's second law, the radius vector drawn from the sun to earth, sweeps out equal areas in equal time, i.e. its areal velocity.

Which of the following is the evidence to show that there must be a force acting on the earth and directed towards the sun?
1 Deviation of the falling bodies toward east.
2 Revolution of the earth around the sun
3 Phenomenon of day and night
4 Apparent motion of sun round the earth.
Explanation:
B Revolution of the earth around the sun is the evidence to show that there must be a force acting on the earth and directed towards the sun. Due to this gravitational attraction between these celestial bodies, centripetal force is generated which binds the solar system together.

Universal time is based on
1 Rotational effect of the Earth about its axis
2 Vibrations of cesium atom
3 Orbital motion of the Earth around the sun
4 Oscillation of quartz crystal
Explanation:
A Universal time is a solar time standard that reflects the average speed of the Earth rotation. It is also called zone (z) time previously called Greenwich Mean Time (GMT)
