The drill used by most dentists today is powered by a small air-turbine that can operate at angular speeds of 350000 {\rm rpm} .
damaskus [11]

Answer:

5833.33

Explanation:

\alpha = Angular acceleration

\theta = Number of revolutions

\omega_i = Initial angular speed = 0

t = Time taken = 2 s

Final angular speed

\omega_f=\dfrac{350000}{60}=5833.33\ rps

From the equation of rotational motion we have

\omega_f=\omega_i+\alpha t\\\Rightarrow \alpha=\dfrac{\omega_f-\omega_i}{t}\\\Rightarrow \alpha=\dfrac{5833.33-0}{2}\\\Rightarrow \alpha=2916.665\ rev/s^2

\theta=\omega_it+\dfrac{1}{2}\alpha t^2\\\Rightarrow \theta=0\times t+\dfrac{1}{2}\times 2916.665\times 2^2\\\Rightarrow \theta=5833.33\ rev

The number of revolutions is 5833.33

What is the basis for analyzing an energy transfer diagram? The mechanical energy input and output must be equal.  Heat must alw
lapo4ka [179]
An Energy Transfer Diagram is also known as Sankey diagram and this shows the input energy taken in and the transformation of the output energy in another form. Therefore the basis for analyzing an energy transfer diagram would be the sum of all outputs must equal the input. Therefore, it is the third option. Hope this answer helps.
