A boy pulls a 48 kg crate with a rope horizontally across the floor. The coefficient of kinetic triction for the crate and the deck is 0.300. The boy exerts a force of 185 N. Draw a free body diagram of the forces acting on the crate. Does the crate accelerate, and if it does at what rate? How fast is it going after 1.2 s, it it started at rest?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
