The mimentum of a 10 kg object moving at a velocity of 20m/s

200kgm/s

Explanation:

Momentum of a body is the product of mass and its velocity. It is also equal to impulse of a force which is the product of force and time.

Momentum = mass x velocity

P = mv

Where

m = 10kg , v = 20m/s

P = 10kg × 20m/s

P = 200kgm/s

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
