It produces only virtual images is the answer
Moving water, wind, gravity, and ice are the five natural agents of erosion
Answer:
605 J
Explanation:
Efficiency = work out / work in
0.78 = W / 775 J
W = 605 J
(150 meters) / (18 seconds) = 8.33 meters per second

Actually Welcome to the Concept of the Kinematics in real world.
So, as given here, we have to find the Mass of the bus from the given momentum, so we get as,
P = m * V
momentum = mass * velocity
here, P= 152625 kgm/s and v= 11.1 m/s
so substituting we get as,
m = 152625 ÷ 11.1 => 13,750 kg
hence,the mass of the bus is 13,750 kg.
