Where are the answers? If there's anything about a white light coming from space I would choose that one.
I think it is this because compression stroke it needs to be compressed then open up when started.
Answer:
v = 10 m/s
Explanation:
recall that velocity is related to wavelength and frequency by the formula
v = fλ
where v = velocity, f = frequency and λ= wavelength
Simply substitute these into the formula:
v = fλ
v = (0.5)(20)
v = 10 m/s
Answer:
The strength of the magnetic field decreases as a result of removing one of those batteries.
Hope this helps!
