Bob has a cup of hot chili. It is too hot to eat.
Kazeer [188]

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.

The table below lists the speed that sound travels through four different materials.One of these materials is a gas, two are liq
Firdavs [7]

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

According to special relativity, in which frames of reference does light in a vacuum travel at less than 3.0 108 m/s?
ch4aika [34]
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.

NEED A PHYSICS EXPERT TO HELP ME PLS
Brut [27]

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

Best Regards!
