In space, a stationary light source emits green light at a frequency of 5.50*10^14hz. a spaceship approaches the light at a speed 1.50*10^7m/s. what is the frequency of the light that is perceived aboard the spaceship. (the speed of light is 3.00*10^8m/s) a.6.08*10^14hz b.4.98*10^14hz c.5.50*10^14hz d.6.77*10^14hz

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,

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.
