Answer:
Ae/A* = 1.115
Explanation:
Let the reservoir pressure be 
Let the exit pressure be 
Ratio of reservoir pressure and exit pressure
= 3.182
For the above value of pressure ratio
Obtain the area ratio from the isentropic flow table
Ae/A* = 1.115
The value of pressure ratio is Ae/A* = 1.115
Answer:
The correct answer is - option A. The mashed potatoes will transfer heat into the gravy.
Explanation:
In this case, where Yamel heats the mashed potatoes but forgets to heat the gravy and put the cold gravy on the hot mashed potatoes. Heat always transfers from the high-temperature object to the low-temperature object. So the hot mashed potatoes will transfer the heat to the gravy according to option A. Cold is not a form of heat but the condition of absence of heat or very low temperature.
Thus, the correct answer is - option A. The mashed potatoes will transfer heat into the gravy.
Answer: If mass remains constant and you double the force you will double the acceleration.
Answer:
in science and engineering , the weight of an object is the force acting on the object due to gravity.
<h3><u>Answer</u>;</h3>
D: 350 N forward
<h3><u>Explanation</u>;</h3>
The Resultant force is defined as the total force acting on a body along with their directions. When the object is at rest or travelling with the same velocity, the resultant force has to be zero.
Force is a vector quantity with both magnitude and direction.
Therefore, the resultant force will be the sum of the forces acting on the table;
Net Force = 200 N + 150 N (since they are acting in the same direction, forward)
<u>= 350 Newtons forward</u>
