The answer to this question is D or the last one
Given that,
Atmospheric Pressure = 14.7 psi
Cooking Pressure = 14.7 +11.1 = 25.8 psi
Take, Atmospheric Temperature = 25 °C
Cooking Temperature = ??
Since, we know that Gas equation is given by:
PV = nRT
or
P ∝ T
P1 / T1 = P2 / T2
14.7/ 25 = 25.8/ T2
T2 = 25*25.8/14.7
T2 = 43.87 °C
The cooking pressure will be 43.87 °C.
The more it is Red shifted.
Answer: More work will be done in case A
Explanation:
Work is said to be done when a force applied to an object causes the object to move through a distance or height.
Work = Force × distance
If the heavy load is pulled straight up with a massless rope, then the object is pulled through a height at an angle perpendicular to the ground (i.e 90°)
Much work will be done in case A and less work in case B. Less work is done in case B due to the use of a machine which is an inclined plane. The use of machine makes work much easier and it allows us to do work in a more convenient manner. It allow us to overcome a much larger load using minimal effort. For the first case, much work will be done since we are carrying through a vertical height which requires more effort compare to when an inclined plane is used.
Also note that the higher the angle of inclination, the more the work done on the object and vice versa
B. Sonar I had the same question what a coincidence but I had a book about it so here's your answer
