A large bottle contains number medical tablets each having a mass of 250 mg. The mass of all tablets is 1kg. Calculate the number of tablets in the
bottle.

First of all, this isn't physics. But, here's the

1 gram is a 1000 milligram and 250 milligram is 250 * 0.001 g which is 0.25 gram.

Since 1 kg is 1000 g, we divide 1000 by 0.25 and we get 1000 * 4 which is 4000.

There are tablets inside the bottle.

thermal energy is the answer

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.
