Heat required to raise the temperature of mercury is given as
here given that
m = 56 g
s = specific heat capacity of mercury = 0.140 J/g C
now here we have
so it required 2265.76 J of heat
A cheetah can run really fast because it is slender which means it is very lightweight and it can move quickly and quietly
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:
Yes, it is possible to add three vectors of equal magnitudes and get zero. This can happen if the resultant of the two vectors are equal and opposite in direction to the third vector.
Fruit flies prefer mates adapted to the same food source.
