Answer:
mv-mu
Explanation:
momentum is the mass by velocity of an object. change in momentum means there was an initial momentum and a final momentum. V represents the final momentum and U represents the initial momentum. So minus the momentum values. (Final momentum (mv) minis initial momentum (mu)
Explanation:
the other 40% is used to power the 60% making it only capable of 60% efficiency
Answer:
2 x 10^-8
Explanation:
the formula of wavelength is
the speed divided by frequency
so you have the speed given = 3.0x10^8m/s
and frequency = 1.5×10^16 Hz
so wavelength = 3.0x10^8m/s / 1.5x10^16 Hz
