<u>Answer:</u>

The wheel will go through 1146 revolutions in 5 minutes.

<u>Explanation:</u>

We can the formula:

\boxed{\omega = \frac{2 \pi}{T}}

where

ω ⇒ angular speed (24 rad/s),

T ⇒ time period (? s),

and solve for T to find the time it takes for the wheel to complete one revolution.

⇒  24 = \frac{2 \pi}{T}

⇒  T = \bf \frac{2 \pi}{24}  s

This means it takes \bf \frac{2 \pi}{24} seconds for the wheel to complete one revolution.

Now, using the unitary method,

In \frac{2 \pi}{24} seconds          ⇒    1 revolution completed

In 1 second              ⇒    1 ÷ \frac{2 \pi}{24}   =  \frac{24}{2 \pi}  revolutions completed

In (5 × 60 = ) 300s  ⇒     \frac{24}{2 \pi}   ×  300   = 1145.9

                                                            ≅ 1146 revolutions completed

Calculate total hole mobility if the hole mobility due to lattice scattering is 50 cm2 /Vsec and the hole mobility due to ionize
Ad libitum [116K]

Answer:

The total hole mobility is 41.67 cm²/V s

Explanation:

Data given by the exercise:

hole mobility due to lattice scattering = ul = 50 cm²/V s

hole mobility due to ionized impurity = ui = 250 cm²/V s

The total mobility is equal:

\frac{1}{u} =\frac{1}{ul} +\frac{1}{ui} \\\frac{1}{u}=\frac{1}{50} +\frac{1}{250} \\u=41.67cm^{2} /Vs
