Hello!
The answer to your question is.
True. Coal is NOT considered a mineral because it is organic and made from the remains of once living things.

The car's (average) acceleration would be
The car's position over time would be given by
so that after 2.4 seconds, the car will have traveled a distance of
Kinetic energy is energy possess by an object due to it motion.
Mass 1; m = 500 Kg Velocity 1; V = 40 m/s
Mass 2; m = 1000 Kg Velocity 2; V = 20 m/s
Formula: K.E = 1/2mv²
For Mass 1 K.E = 1/2(500 Kg)(40 m/s)² = 400, 000 J
For Mass 2 K.E = 1/2(1000 Kg)(20 m/s)² = 200,000 J
This solution shows that a larger velocity will have a greater kinetic energy.
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.
