Answer:
Fire extenguisher and refrigerator
Refrigerator : There are 5 basic components in refrigeration I.e. fluid refrigerant, a compressor which controls the flow of refrigerant; the condensor coil( on the outside of the fridge), evaporation coils( on the inside of the fridge) and something calls an expansion device.
The compressor constricts the refrigerant vapour,raising its pressure and pushes it in the coils on the outside of the refrigerator.
When the hot gas in the coils meets the cooler air temperature of the kitchen it becomes a liquid.
Now in the liquid form at high pressure, the refrigerant cools down as it flows into the coils inside the freezer and the fridge.
The refrigerant absorbs the heat inside the fridge cooling down the air.
Last the refrigerant evaporates to a gas then flows back to the compressor where the cycle starts all over.
Fire Extinguishers: Water performs two functions; its conversion tosteam absorbs the heat, and the steam displaces the air from the vicinity of the flame. Many siimple fire extinguishers are quipped with hand pumps or sources of compressed gas to propel water through the nozzle.

Answer:
P = 600 W
Explanation:
The formula used for calculating Power using the Voltage and current is given by:
P = V * I
Here V is the value of voltage and I is the applied current.
Given:
I = 5 A
V = 120 V
so by using these values in the formula, we get
P = V * I
P = 120 * 5
P = 600 W
So 600 W power is consumed by a load drawing 5 A with 120 V across it.
Answer:
their relative positions in the parameter and argument lists.
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
A parameter can be defined as a value that must be passed into a function, subroutine or procedure when it is called.
Generally, when parameters are passed between a calling code and the called function, formal and actual parameters are usually matched by their relative positions in the parameter and argument lists.
A formal parameter is simply an identifier declared in a method so as to represent the value that is being passed by a caller into the method.
An actual parameter refers to the actual value that is being passed by a caller into the method i.e the variables or values that are passed while a function is being called.
