The second law describes the relationship between force, mass and acceleration; like Force (Newtons) equals Mass Time Acceleration. Newton's first law defines inertial reference frame as that reference frame where an object will move with constant velocity if no forces are acting on point mass.
Hope this helps you =)
The force pushing against an area or surface
The heat to evaporate the water in the sweat comes from the skin and provides a cooling effect. The body then does not overheat. hope it help
True
The greater the object weighs (volume) the heavier it is, and it the object is heavier, the the buoyancy force will be higher
Hope this helps :)
