Heat flow occurs when two systems in contact are not at the same temperature.
What is heat flow?
- when two bodies of different temperatures are in contact, heat flow takes place.
- Heat flows till the two bodies in contact achieve equilibrium.
- To achieve equilibrium, heat flows from hotter bodies to colder bodies.
- There is no heat flow after achieving the state of equilibrium because the amount of heat flow from one body to the other is the same.

Answer:
The minimum stopping distance when the car is moving at
29.0 m/sec = 285.94 m
Explanation:
We know by equation of motion that,
Where, v= final velocity m/sec
u=initial velocity m/sec
a=Acceleration m/
s= Distance traveled before stop m
Case 1
u= 13 m/sec, v=0, s= 57.46 m, a=?
a = -1.47 m/ (a is negative since final velocity is less then initial velocity)
Case 2
u=29 m/sec, v=0, s= ?, a=-1.47 m/ (since same friction force is applied)
s = 285.94 m
Hence the minimum stopping distance when the car is moving at
29.0 m/sec = 285.94 m
Answer:
C. Angle of Attack.
Explanation:
The pilot must adjust the angle of attack parameter. The angle of attack of this plane to get to the desired lift coefficient.
And thus, we have
Lift = Weight
