B) 3. A car is travelling at initial speed u = 32 m/s. It then starts to decelerate with a = -2.0 m/s2
for 8.0 seconds.
a) What is the speed of the car after 8.0 seconds?
b) How far did the car travel during those 8.0 seconds?

the higher the current the higher the mag field around it the higher the influence on the compass

its a 5.5 n

glad that

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
