a bulldozer does 4500 J of work to push a mound of soil to the top of a ramp that is 15 M High the ramp is at an angle of 35 degrees to the ground how much force does a bulldozer apply to the mound of soil round your answer to 2 significant figures

Because they're in different places for this the temperature varies.

Gotta have a picture ^^

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3

It would end up being d
