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.

If g were 15 instead of 9.81, what would your quads look like?
Jlenok [28]

Answer:

Quads will have more energy

Explanation:

If the acceleration due to gravity increases from 9.81 to 15, then the velocity will increase as the rate of changing velocity i.e acceleration has increased from 9.81 to 15 m/s^2

With increase of velocity, the energy and force will also increase. Hence, the squad will require/have higher energy.

What is a cool example of newtons 3rd law?
USPshnik [31]
<span>This law means that when one object exerts force on another, the same amount of force is exerted on the initial object, but in the opposite reaction. For example, when a billiard ball strikes another ball, the second ball is propelled forward. Simultaneously, the momentum of the first ball is slowed or stopped by opposing force. The amount that the first object is affected by the opposing force depends on the mass and motion of the second object.</span>
