Sarah heated two cubes of aluminum to 50°C. Cube A has a volume of four cubic centimeters. Cube B has a volume of two cubic cent
dalvyx [7]

Cube A has more thermal energy than cube B.

Explanation:

It is obvious that cube A has gained more thermal energy compared to cube B.

From the description of the experiment, both cubes had the same temperature which is 50°C. Temperature is the degree of hotness or coldness of a body.

Thermal energy is a form of energy expressed as heat in a body.

Cube A has a higher volume because it has gained more thermal energy than Cube B.

Thermal energy increases the rate of vibration of atoms in the crystal lattice of the solid. The more the thermal energy, the more the vibration. This is  why Cube A has expanded so much and changed volume.

This is the Doppler effect.

1. As the sound leaves the horn the sound waves are at first close to each other and as they move outwards they become further apart. The closer the sound waves are the louder the noise.

As the car gets the closer the sound waves get closer, so the horn becomes louder.

2. As the horn moves away, the sound waves become less frequent, causing the pitch to get lower.

A bowling ball has a mass of 5 kg what happens to its momentum when its speed increases from 1m/s to 2m/s?
Mama L [17]
Here, Initial momentum = mu = 5*1 = 5 Kg m/s
Final momentum = mv = 5*2 = 10 Kg m/s

So, Momentum has been increased from 5 Kg m/s to 10 Kg m/s. Hence, Your Final answer is option B

Hope this helps!
