The distance from earth to the nearest stor is about 4 x 1016 meters. How long would it take a radio signal traveling at the speed of light, 3,0 x 10 m/s, to make a one way trip to this star?

(75°f − 32) × 5/9 = 23.889°c

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
