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.
Answer:
say a lighter car is going 80mph and a heavier car is going the same speed who do you think will have more damage i will say the heavier car
Explanation:
Answer:
Answer is option b) 2.97m
Explanation:
With the relationship between the force exerted by the runner and the mass that it has, I can determine the acceleration it will have:
F= m × a ⇒ a= (650 kg ×(m/s^2)) / (70kg)= 9.286 (m/s^2)
With the acceleration that prints the force exerted and the time I can determine the distance traveled in the interval:
Distance= (1/2) × a × t^2 = (1/2) × 9.286 (m/s^2) × ((0.8s)^2)= 2.97m
C
I took the tests earlier hope this helps
