URGENT! If Frydo runs across the yard at a velocity of 2.5 m/s meters East for 90 seconds. What is his displacement?

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
