We know, F = m*a
749 = m * 10.6
m = 749 / 10.6
m = 70.66 Kg
In short, Your Answer would be 70.66 Kg
Hope this helps!
Explanation:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
Glass loses electrons easily and silk takes them. Because electrons are negatively charged, the glass rod becomes positive and the silk becomes negative.
Work is Force x Distance in the Direction of the force.
