The mechanical engery of an object equals its

1 answer:

4 0

The sum of an object's potential and kinetic energies is called the object's mechanical energy. As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

Kryger [21]

Answer:

The right solution will be the "2v".

Explanation:

For something like an object underneath pure rolling the speed at any point is calculated by:

⇒ $v_{rolling}=v_{translational}+v_{rotational}$

Although the angular velocity was indeed closely linked to either the transnational velocity throughout particular instance of pure rolling as:

⇒ $\omega=\frac{v_{translational}}{r}$

Significant meaning is obtained, as speeds are in the same direction. Therefore the speed of rotation becomes supplied by:

⇒ $v_{rotational}=\omega \times r$

On substituting the estimated values, we get

⇒ $=\frac{v_{translational}}{r} \times r$

⇒ $=v_{translational}$

So that the velocity will be:

⇒ $v_{rolling}=v+v$

⇒ $=2v$

irina [24]

Answer:

Required materials for electroplating are - battery or electric supply, cathode, anode and salt solution of material to be coated. Electroplating is the process of releasing ions from electrolytes and coating them as atoms on required material.
