Explain the limitations of electrical energy production created exclusively by renewable energy sources.

Diano4ka-milaya [45]

Answer:

The main limitation while the production of electrical energy is that the source from which electrical energy products cannot be available all the time

Explanation:

The main limitation while the production of electrical energy is that the source from which electrical energy products cannot be available all the time. There can be many factors that can hinder the availability of the source. for example, the Availability of solar energy can be hindered due to the cloud.

one the other important thing that needs to be taken into consideration is that although renewable energy is considered to be environment-friendly but to rely on this point cannot be true always

With the aid of a string, a gyroscope is accelerated from rest to 32 rad/s in 0.40 s. What is its angular acceleration in rad/s2

Irina-Kira [14]

<h2>Angular acceleration is 80 rad/s² </h2><h2>Number of revolutions undergone is 1.02</h2>

Explanation:

We have equation of motion v = u + at

Initial angular velocity, u = 0 rad/s

Final angular velocity, v = 32 rad/s

Time, t = 0.40 s

Substituting

v = u + at

32 = 0 + a x 0.40

a = 80 rad/s²

Angular acceleration is 80 rad/s²

We have equation of motion s = ut + 0.5 at²

Initial angular velocity, u = 0 rad/s

Angular acceleration, a = 80 rad/s²

Time, t = 0.4 s

Substituting

s = ut + 0.5 at²

s = 0 x 0.4 + 0.5 x 80 x 0.4²

s = 6.4 rad

Angular displacement = 6.4 rad

$\texttt{Number of revolutions = }\frac{6.4}{2\pi}=1.02$

Number of revolutions undergone is 1.02
