Because the temperature of the place its contained in is constantly changing, for example, if you put a room temperature item in the fridge it will become cold, or whatever the temperature you set your fridge to.
Answer:potential energy=810000j
Kinetic energy=810000j
Mechanical energy=810000j
Explanation:
Mass(m)=5000kg
Velocity(v)=18m/s
Kinetic energy=(mxv^2) ➗ 2
Kinetic energy =(5000x18^2) ➗ 2
Kinetic energy =(5000x18x18) ➗ 2
Kinetic energy =1620000 ➗ 2
Kinetic energy =810000j
Kinetic energy = potential energy
Since energy can neither be created nor destroyed
Answer:

Symbols such as cross motivates me to go to church.
Answer:
A & B are correct
Explanation:
Certain automotive sensors like crank shaft position sensor uses a.c. while most automotive components require DC to work properly through the battery which is incorporated with an alternator to keep it charged through a diode while continual supply of DC is sustained.
