Ans 1. contact forces are the forces acting on a body by a physical contact or a touch...

example such as the force of collision between two bodies... and force exerted by a compressed spring.

non contact forces are the forces which are applied on a body without any physical contact or touch ..

example = electrostatic force, force of gravity and magnetic forces...

ans 2) bags and suitcases are provided with broad handles because more the area of contact lesser will be the force or weight that is it will be easier for us Carry the bag and the suitcase if the force exerted by the bag on our shoulders is less ....

ans 4) the factors are humidity and moisture of that place...

ans 5) when two like charges are brought in contact it repels like if the North pole of one magnet is brought near the North pole of another magnet it repels.... now if two unlike charges are brought in contact then it attracts like if the South pole of a magnet is brought near the North pole of a magnet then it attracts..

ans 7) mass weight

the mass of a the weight of a body is the

body is the quantity amount of mass contained

of matter contained in the body.... its si unit is

in it.. it's si unit is Kg. Newton

ans 8) when we climb up in higher altitudes our blood pressure increases there due to high blood pressure nose starts bleeding. The main concept here is that pressure decreases with increase in altitude..

ans 9 ) when a solid is kept at a surface it exerts pressure only at its base due to its weight.. but a liquid exerts pressure in all sides and all directions of the container in which it is kept.. it is due to the thrust exerted by the liquid..

ans 10) the pressure will decrease as the area is doubled.

the answers which I knew I did those ..

plz mark me as brainliest for all these work...
