You observe someone pulling a block of mass 33 kg across a low-friction surface. while they pull a distance of 4 m in the direction of motion, the speed of the block changes from 4 m/s to 6 m/s. calculate the magnitude of the force exerted by the person on the block. what was the change in internal energy (chemical energy plus thermal energy) of the person pulling the block?

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
