Answer:
B. It has increased the chili's potential energy
Explanation:
When there is an increase in the kinetic energy of a substance, the vibrations of atoms and molecules of the substance increases.
This kinetic energy increases the thermal energy of the substance.
So, when there is a decrease in the thermal energy of a substance, the kinetic energy decreases because the random motion of the molecules or atoms becomes feeble.
If the kinetic energy of the substance decreases, the potential energy of the substance increases.
So, if the chili has cooled after 10 minutes, it has increased the potential energy of the substance.
To minimize loss of heat or absorption of heat from surroundings
Answer:
False.
Explanation:
This question refers to the rules of American Football. Thus, the line of scrimmage is an imaginary boundary that is established between both teams, to which the offensive line and the defensive line go to start the play.
In this situation, the offensive team must have 7 players in its formation, but within this some players can perform certain movements, with which it is incorrect to say that the formation cannot be modified, since it is constantly seen as some players, such as wide receivers, for example, move during scrimmage formation.
Answer:
The answer to your question is the letter C. 3 Watts
Explanation:
Data
Power = ?
Force = 20 N
Distance = 1.5 m
time = 10 s
Formula
Work = force x distance
Power = Work/time
Process
a) Calculate the Work
Work = 20 x 1.5
Work = 30 J
b) Calculate the Power
Power = 30J/10s
Power = 3 Watts
The units of Power are Watts and the units of Work and energy are Joules.
A because light is the fastest thing on this earth
