An automotive air conditioner produces a 1-kW cooling effect while consuming 0.75 kW of power. What is the rate at which heat is
1 answer:
Answer:
The rejected by the air conditioning system is 1.75 kilowatts.
Explanation:
A air conditioning system is a refrigeration cycle, whose receives heat from cold reservoir with the help of power input before releasing it to hot reservoir. The First Law of Thermodynamics describes the model:
Where:
- Heat rate from cold reservoir, measured in kilowatts.
- Heat rate liberated to the hot reservoir, measured in kilowatts.
- Power input, measured in kilowatts.
The heat rejected is now cleared:
If and
, then:
The rejected by the air conditioning system is 1.75 kilowatts.

By definition, speed is the integral of acceleration with respect to time.
We have then:
As the acceleration is constant, then integrating we have:
Where,
vo: constant of integration that corresponds to the initial velocity
We observe then that the speed varies linearly when the acceleration is constant .
Therefore, for constant acceleration, the velocity is changing.
Answer:
an object with a constant acceleration always have:
A. changing velocity
Answer: Tangential Velocity
The tangential velocity is defined as the angular velocity
by the radius
of circular motion. As shown below:
Its name is due to the fact that this linear velocity vector is always tangent to the trajectory and is the distance traveled by a body or object in a circular movement in a period of time.
