Mr.Arocena i kinda get the math that we were suppost to do the one that is due monday but could i have a little extra help tomorrow in the morning or at lunch? i just dont wanna do them and then find out they are all wrong i got some right today :) are you free to help?
mr arocena i dont get question 3 on the assignment from today.
to find the distance to an object in space a radio telescope bounces radio signals off the object and measures the time it takes for the signals to make a round trip. radio signals travel at 29800 km/s in space. the formula for the distance to an object is 29800 x t d= 2 and the number is 2.45 in a) would i use 2.45?

ReplyDeleteFor question 3 from today's assignment (page 119) yes the 2.45s is the time (which in the equation is the variable t)
