Question

STATE WHETHER THE FOLLOWING STATEMENTS ARE TRUE/FALSE.CORRECT THE STATEMENT IF IT IS FALSE
1.The linear momentum of a system of particles is always conserved
2.Apparent weight of a person is always equal to his actual weight
3.Weight of a body is greater at the equator and less at the polar region
4. Turning a nut with a spanner having a short handle is so easy than one with a long handle 5. There is no gravity in the orbiting space station around the world.So the astronauts feel weightlessness ​

Answer 1

HEY MATE!

1) False

Liner momentum is conserved only when their is no external force present on system of particles.

2) False

We actually experience a gravitational force on earth which makes the difference between our actual weight and apparent weight.

3) True

Weight decrease when we move from polar region to equatorial region due to change of gravitational force.

4) True

Force applied with a short spammer does deviates its direction while we move our hand but with a large one we may struggle to do the same.

5) False

Gravity is present where space stations orbit but the value of gravitational force decrease drastically when we go thousands of kilometers far from Earth's surface.

CORRECT STATEMENTS

1) Linear momentum for a system of particles is always conserved if no external force act on it.

2)Apparent weight is greater than actual weight .

5) Gravity is 0 when we reach out of the gravitational field of Earth.

Hope it helps
