The 2 ft side length of the scale drawing corresponds to a side length of 120 feet for the actual skate park. What is the scale
SOVA2 [1]

Answer:

The scale factor is \frac{1}{60}

Step-by-step explanation:

we know that

The scale factor is equal to the ratio between the side length of the scale drawing to the corresponding side length in the actual

so

\frac{2}{120}=\frac{1}{60}

Electrons execute 1.4*10^6 revolutions per sec in a magnetic field of flux density
seropon [69]

The charge of the electrons is 8.02 \times 10^{-19} \ C.

The given parameters:

  • <em>Number of revolution of the electron, N = 1.4 x 10⁶ rev per sec</em>
  • <em>Flux density, B = 10⁻⁵ T</em>
  • <em>Mass of electron, m = 9.11 x 10⁻³¹ kg</em>

<em />

The angular speed of the electron is calculated as follows;

\omega = 2\pi N\\\\\omega = 2\pi \ \frac{rad}{1 \ rev} \times 1.4 \times 10^6 \ rev/s\\\\\omega = 8.798 \times 10^6 \ rad/s

The charge of the electrons is calculated as follows;

F_c= m\omega ^2 r\\\\F_{B}= qvB = q\omega r B \\\\F_c = F_B\\\\m\omega ^2 r =  q\omega r B \\\\q = \frac{m\omega ^2 r}{\omega r B} \\\\q = \frac{m \omega }{B} \\\\q = \frac{9.11 \times 10^{-31} \times 8.798 \times 10^6}{10^{-5}} \\\\q = 8.02 \times 10^{-19} \ C

The charge of the electrons is 8.02 \times 10^{-19} \ C.

The complete question here:

Electrons execute 1.4*10^6 revolutions per sec in a magnetic field of flux density 10⁻⁵ T. What will be the value of charge of the electron?
