Answer:
6s
Explanation:
Assume it is dropped from rest and the gravitational acceleration is 10
By the equation of motion under constant acceleration:

180 = (0)t+10(t^2)/2
t = 6 or -6 (rejected)
t = 6 s
B- light bends as it passes through an object ( a would be reflect)
A. Acceleration.
acceleration is m/s^2. speed is m/s
Answer:
Gases that are very good at absorbing long wave photons of infrared light
Explanation:
- Green house gases examples are Carbon monoxide, nitric oxide etc.
- These gases absorb long wave photons of infrared light of sun's rays
- They melts the glaciers and increase the sea level .
