Water has a high specific heat capacity. Oil has a smaller heat capacity.
The same braking force does work on these objects to slow them down. The work done is equal to their change in kinetic energy:
FΔx = 0.5mv²
F = force, Δx = distance traveled, m = mass, v = speed
Isolate Δx:
Δx = 0.5mv²/F
Calculate Δx for each object.
Object 1: m = 4.0kg, v = 2.0m/s
Δx = 0.5(4.0)(2.0)²/F = 8/F
Object 2: m = 1.0kg, v = 4.0m/s
Δx = 0.5(1.0)(4.0)²/F = 8/F
The two objects travel the same distance before stopping.
The particles that move in orbits of the same radius have the same momentum.

Orbital angular momentum:</h3>
A point particle's three-dimensional angular momentum is traditionally represented by the pseudovector r p, which is the cross product of the particle's position vector r (relative to some origin) and momentum vector, which in Newtonian physics is denoted by p = mv.
L = mr
= mr²w is the particle's orbital angular momentum in units of magnitude. The part of the particle's velocity that is here perpendicular to the axis of rotation is designated as 
The right-hand rule indicates the direction of the angular momentum. In isolated systems, the angular momentum is conserved.

Answer:
Mirages are formed when the ground is really hot and the air is really cold. The hot ground will warm a layer of the air closest to the ground. When the light moves through the cold air and hits the warm air it bends creating the U shaped bend

Answer:
The work done is 12 MJ.
Explanation:
The engine of a car exerts a constant traction force of F=4000N . Assume that the car is moving at a constant speed of 36 km/hr. In five minutes, what is the work done by the engine's traction?
Force, F = 4000 N
speed, v = 36 km/h = 10 m/s
time , t = 5 minutes = 5 x 60 = 300 s
Work done is given by
W = force x distance
W = 4000 x 10 x 300 J = 12 x 10^6 J = 12 MJ
