Explanation:
there is no relationship between small mass and the bigger mass, but it can be related with the acceleration. Since Force is constant, acceleration is inversely proportional to the mass. Greater the mass, lesser is the acceleration and vise versa
Answer:
M = 50 kg / sec * 60 sec = 3000 kg water that falls
PE = M g h initial potential energy of water
PE = 3000 kg * 9.8 m/s^2 * 20 m = 588,000 joules of energy lost
Answer:
Only technician A is correct
Explanation:
Analysis of technician A's statements
The refrigeration cycle contains four major components: the compressor, condenser, expansion device, and evaporator. Refrigerant remains piped between these four components and is contained in the refrigerant loop.
The refrigerant begins as a cool vapor and heads to the first component:
1. the compressor
It forces the refrigerant through the system. In the process of being compressed the cool, gaseous refrigerant is turned to a very hot and high-pressure vapor.
Analysis of technician B's statement
The condenser’s job is to cool the refrigerant so that it turns from a gas into a liquid, or condenses. This happens when warm outdoor air is blown across the condenser coil that is filled with hot, gaseous refrigerant.
The evaporator is responsible for cooling the air going to the space by boiling (evaporating) the refrigerant flowing through it. This happens when warm air is blown across the evaporator as cold refrigerant moves through the evaporator coil. Heat transfers from the air to the refrigerant, which cools the air directly before it is vented to the space.
Answer: Electric field is given as
E = V/d
E = 220 v / 0.0056m
E = 39285.71 v/m
Or
E = 39285.71 N/C
Explanation: Therefore electric field is 39285.71 V/m
Answer:
Electric field, 
Explanation:
It is given that,
Distance between inner and outer wall of a cell membrane, d = 10 nm
Charged density of a parallel plate capacitor, 
It is assumed to find the electric field between the membranes. We know that the electric field between the parallel plates is given by :
E = 1129943.50 N/C
or
So, the electric field between the cell membranes is 
. Hence, this is the required solution.
