During the period of inflation, the universe may have briefly expanded at 1030 ( a million trillion trillion) or more times the speed of light. Why did this ultra rapid expansion not violate Einstein's special relativity, which says that neither matter nor communication can move faster than the speed of light.

8. why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis? (hint: what did the article say about the advantages of digital signals? )

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
