Answer:
Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.
I believe it is A bit not completely sure
Answer:
20 N
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma
= 5 × 4 = 20 N
Part a is simply mass*gravity. Tension=ma
Part b Tension= 50kg(10m/s+5.0m/s) = 750N
