Newton's Second law of motion Newton's First law of motion
Newton's Third law of motion Law of conservation of energy

362)Freely falling bodies have the same-
acceleration velocity
speed force

363)Weight of a body is-
mass force
momentum force with which it is attracted to the earth

364)The acceleration due to grvity 'g' is zero
on the surface of the earth at the centre of the earth
on the sea level on the mount Everest

365)A loaded truck and a car moving at the same velocity, which one will have more kinetic energy?
Truck Car
Both will have same kinetic energy None of these

366)In a circuit 1.2amp current is flowing due to 3.6volt potential difference, the resistance is
1/3 ohm 3 ohm
30 ohm 1ohm

367)The scientific principle on which radio and television work is

propagation of electromagnetic waves magnetism

368)In planetary motion
linear momentum remains constant linear speed remains constant
Angular momentum remains constant Angular speed remains constant

369)Having temperature constant the speed of sound in humid air as compared to dry air is
more less
same speed of sound is indipendent of characteristics of medium
