Chapter name please then I can answer
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,
I would say A- fossils and B- land change
He noticed that there was similar things in 2 different places
The product of an object's mass and velocity is B.momentum.

Omitting the 1 will not change the value of the number, but will change the units at the end of the problem
