Answer:
Explanation:
The first part of this question is simply asking us to convert the speed from miles per hour to meters per second:
choice C.
The next part wants us to use the equation for acceleration and find the acceleration:
where v is final velocity, v0 is initial velocity, and t is time in seconds (which was one of the reasons we had to convert the initial velocity from 60.0 mph to m/s):
and
a = 10.7 m/s/s, choice B.
Answer:do it correct and do your best please yourself do what is right let every body know this is ak200342 talking to you.
Explanation:keep your head up.
Explanation:
∆x=300 m×2
∆t=1.5 s
v=∆x/∆t → v=2×300/1.5 = 400 m/s
5.4 x 1014Hz
wavelength x frequency = the speed of light
Wave speed = frequency (in Hz) x wavelength (in m) so wave speed = 11 x 0.011 = 0.121 m/s
