Ahiker, who weighs 985 n, is strolling through the woods and crosses a small horizontal bridge. the bridge is uniform, weighs 3610 n, and rests on two concrete supports, one at each end. he stops one-fifth of the way along the bridge. what is the magnitude of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
