Work is defined as the force times the distance which is mathematically expressed W = Fxd. The given force is 5x10^4 and the distance is 10000 m (the distance is converted as meter because Nm = J) the work done by the wind is W = 5x10^4 N (10000) = 500 x 10^6 Joules. I hope it answered your question
Answer:
Your answer should be A. 0.25 J and moving to the right
Explanation:
A. True
if cold air is replacing warm air it is a cold front and vice versa.
Compression and rarefraction, the other guy's answer it's wrong
Potential energy due to gravity = Ep = mgh [symbols have their usual meaning ]
Evidently, HALVING the mass will make Ep , HALF its previous value. So, It will be halved.
