Why can the sun transmit heat to earth only by radiation? . the space between the sun and earth contains almost no matter.. radiation transmits heat through the motion of a gas.. radiation does not require the creation of electromagnetic waves.. the molecules in the sun are moving too fast to cause conduction.

Plzz 10 points ! is some thermal energy always released during a transformation ? and is potential chemical energy always transformed into kinetic energy

If you have a bowl with six apples and you take away four, how many do you have? anyone take a guess and post it. lol getting rid of my account might as well do it with some fun

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)
