Which of the following explains the transfer of heat between two objects? A. flow of temperature from one object to the other B. flow of caloric from one object to the other C. collisions between particles only within each object D. collisions of particles of one object with those of the other object ***not sure!! :( Thank you!! :D
Answers
D is the correct answer.
Final answer:
Heat transfer between two objects happens when energy transfers from the hotter object to the colder object until they reach thermal equilibrium. This can happen through conduction, convection, and radiation.
Explanation:
The transfer of heat between two objects is best explained by the principle that energy is transferred from the hotter object to the colder object, and this occurs until both objects have reached the same temperature. This transfer of heat energy happens primarily through three processes known as conduction, convection, and radiation.
Conduction is the transfer of heat between two objects in direct contact with each other, such as a hot pan warming up food. Convection is the transfer of heat due to the movement of mass, typically within fluids like air or water. Radiation is the transfer of heat through electromagnetic waves, like the heat you feel from the Sun on a sunny day.
When two objects of different temperatures come into contact, like object X with temperature Tx and object Y with temperature Ty, heat flows spontaneously from the hotter object X to the colder object Y. This results in a loss of thermal energy in X and a gain in thermal energy in Y, until both reach a state of thermal equilibrium.

1. If we would like to find the velocity, we must calculate the distance from initial to final,
2. If we would like to find the speed, we must calculate the total distance that travelled (
So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
If you mean average velocity, it is 0/10 = 0 km/h

Answer:
equation gives the position at a specific time for an object with constant acceleration
Explanation:
equation gives the position at specific time for an object having constant acceleration. Constant acceleration is referred as the change of velocity with respect to the time is known as the acceleration, but when the velocity changes occurs at constant rate this rate is termed as the constant acceleration. The constant acceleration can never be zero. The velocity changes but that change occurs in the consistently. The acceleration is affected by the mass.
