What is solid matter and can we covert matter into something else

1 answer:

6 0

Answer: Solid matter is one of the three main states of matter, along with liquid and gas. Matter is the "stuff" of the universe, the atoms, molecules and ions that make up all physical substances. In a solid, these particles are packed closely together and are not free to move about within the substance.

All matter exists as solids, liquids, or gases. These are called the states of matter. Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid).

Answer:

72 J

Explanation:

Total kinetic energy will be tge sum of rotational and translational energy.

Rotational kinetic energy is given by $0.5I\omega^{2}$ where I is moment of inertia which is given by $mr^{2}$ and here m is mass, r is radius. Also, $v=\omega r$ hence making \omega the subject then $\omega=\frac {v}{r}$ where v is the velocity.

Rotational kinetic energy= $0.5I\omega^{2}=0.5mr^{2}\times(\frac {v}{r})^{2}= 0.5mv^{2}$

This is same as the formula for translational kinetic energy which is given by $0.5mv^{2}$

Therefore, total kinetic energy= $0.5mv^{2}+0.5mv^{2}=mv^{2}$

Substituting m with 2 kg and v with 6 m/s then total energy will be $2\times 6^{2}=72 J$

What is centripetal force

KonstantinChe [14]

Answer:

Centripetal force is defined as, "the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.

Explanation:

Just a few examples are the tension in the rope on a tether ball, the force of Earth's gravity on the Moon, friction between roller skates and a rink floor, a banked roadway's force on a car, and forces on the tube of a spinning centrifuge. Any net force causing uniform circular motion is called a centripetal force.
