A spaceship approaches the light at a speed 1.50*10^7m/s which is about 5% of light speed. So the green light will shift towards the blue end of spectrum due to "blue shift."
The frequency should be higher which rules out option B and C. Looking at the magnitude of change, the correct answer should be A.6.08*10^14Hz,
Answer:
An electric chemical cell is not always needed to have a power circuit. But every other part is.
Potential energy is in short, stored energy
Use the Second Law of Newton, which states that Net Force = mass times acceleration
F = m * a
F = 50 kg * 1.5 m/s^2 = 75 N
Answer: option C
