Answer:
$39,500
Explanation:
In order to find the total cost, we proceed as follows:
1)
First, the base fee is:
2)
Then we calculate the total number of questions: we have 15 questions per survey, and a total of 500 surveys (for 500 people), therefore the total number of questions is
Since the cost is $5 per question, the total cost of the questions is
3)
Finally, we have 500 persons, and there is a cost of $2 per each person, so the cost due to this is
Therefore, the total cost is:
Answer:
Explanation:
Once the centrifugal forces are equivalent as an object rotates, it is called "in equilibrium." If the point of impact of the moving object does not align with the center of the rotation, unequal centrifugal forces are produced and the rotating component is "out of equilibrium."
Two conditions for balanced condition are: static and coupled. Static equilibrium relates to a one plane mass in which the unit is balanced by weight inverse the unbalanced mass
formula used to calculate centrifugal mass is
where, m is mass, v is speed of body. r is radius
Answer:
No.
Explanation:
The Coefficient of Performance of the reversible heat pump is determined by the Carnot's cycle:
The power required to make the heat pump working is:
The heat absorbed from the exterior air is:
According to the Second Law of Thermodynamics, the entropy generation rate in a reversible cycle must be zero. The formula for the heat pump is:
Which contradicts the reversibility criterion according to the Second Law of Thermodynamics.
