VF=0
Vi=60mph
T=4.0s
you need to convert hours to seconds... so you do there is 60 minutes in an hour and there is 60 seconds in a minute so you do 60*3=180
180/4.0=45m/s^2
Answer:
|A| = √(Ax)^2 + (Ay)^2
|A| = √(7.6)^2 + (-6.4)^2
|A| = √98.72
|A| = 9.9
The answer is D.
C and A are incomplete as they only treat specific types of energy, and B doesn't answer the question.
I do not know what the school expects as an answer, but advantage of reflecting telescopes is that there is only one major reflecting surface, so it is quite easy to create a 6 or 8 inch telescope by an amateur, after adding on a prism and an eyepiece. (a microscope eyepiece could be used).
MY answer would be "easier to build". (it still takes tens of hours to grind and polish the single plane surface to a parabolic surface).
Electromagnetic waves all have the same velocity in the same medium. However, since frequencies vary widely, so do wavelengths.
Answer: a sock and a Pepe when the Pepe is rubbed by the sock the energy is enormous
