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.
In order to find the solid, you would want the object in which sound travels the fastest
In this case, since in object C, the speed of sound is the fastest, it is the most likely to be a solid
So object C is most likely to be a solid
The correct option is D.
According to special relativity, in no frame of reference does light in a vacuum travel at less than the speed of light, the speed of light in a vacuum is the same for any inertial reference frame.This fact remain valid no matter the speed of a light source relative to another observer.
Answer:
Discharge Rate = 0.2 cubic meters per second
Explanation:
Torricelli's Law is derived from Bernoulli's equation and simply states that the speed of the efflux in a Torricelli apparatus (shown below) is directly proportional to and affected only by the height of the fluid above it.
V = √2g(10-2)
Putting value of g = 9.8 we get:
V = 12.52 m/s
Discharge rate = Q = A × V
= 1.60/100 × 12.52
= 0.2 cubic meter per second

I believe it’s B but I suggest u chec
