An object is dropped from rest at a height of 150 m and simultaneously
another object is dropped from rest at a height 100 m. What is the difference
in their heights after 2 s if both the objects drop with same accelerations?
How does the difference in heights vary with time?
what are the characteristics of gravitational force.......????
relative density of gold is 19.3.if the density of water is 1000kg/m3 ,what is density of gold in si unit?

difference between mass and weight
A sharp knife is more effective than a blunt knife.why?
WHAT IS THE S.I. UNIT OF UPTHRUST?
what is the difference between thrust and force?
How archimedes principle is used to determine the purity of gold?
the acceleration due to gravity on a planet is 1.96m/s2 .If it is safe to jump from a height of 3m on the earth, the corresponding height of the planet will be ?
a stone is allowed to fall from the top of a tower 100m high and at the same time another stone is projected vertically upwards frome the ground with a velocity of 25ms-1 . calculate when and where the 2 stones will meet.
When an object is immersed into the fluid two forces act on the object in the vertically opposite directions. Name them and also write the factors on which the magnitude of these forces depends on.
A body weighs 63 N on the surface of the earth. What is the gravitational force exerted on it due to the earth at a height equal to half the radius of the earth?
