Which one looks like a screw
A is shoes
B is a fork (lever)
C is a wind chime shaped like a screw
D is a stapler (lever)
Reflection- serious thought or consideration
Absorption- the process or action by which one thing absorbs or is absorbed by another.
Diffusion- the spreading of something more widely.
Diffraction- the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.
Refraction- measurement of the focusing characteristics of an eye or eyes
Answer:
C) According to the second law of thermodynamics, not all energy from the burnt fuel is used to do work on the piston. It also produces heat which warms other parts of the car.
Explanation:
A) According to the fourth law of thermodynamics, the temperature of the other parts of the car increases due to the coolant used for the engine.
B) According to the first law of thermodynamics, the hood of the car heats up using heat from the surroundings in-order to achieve thermal equilibrium with the engine.
C) According to the second law of thermodynamics, not all energy from the burnt fuel is used to do work on the piston. It also produces heat which warms other parts of the car.
D) According to the third law of thermodynamics, the increase in the velocity of the car changes the entropy of the tires. To balance this change, the temperature of the other parts is increased.
To solve this problem, we must basically count the total energy lost converting all the values given in the international system.
The energy loss is given by both 124KJ and 124food heats.
Since the energy conversion we know that 1 food calories is equal to 4,184J. So:
Therefore the total energy lost will be
Therefore the total energy lost to the surroindings in form of heat is 124.518kJ
