A space shuttle astronaut has a mass of 110 kg with her space suit on. She is on a space walk and picks up a full can of spray with a mass of 20.6 kg. Relative to the space shuttle, she is at rest. She then holds the can directly in front of her centre of mass to avoid rotation and releases 5.0 kg of spray at a speed of 15.6 m/s . Her speed, relative to the space shuttle, when she has stopped spraying is approximately

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth

If your workout exceeds an hour you should substitute "a sports drink" for water.hope my answer has you : )

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

Change of odor change of color for example, silver to reddish-brown when iron rusts. change in temperature or energy, such as the production (exothermic) or loss (endothermic) of heat.hopefully this ! : )
