Mathematics
1 answer:
seropon [69]3 years ago
8 0

Answer:

The answer is 0

Step-by-step explanation:

Since any number squared by zero is 1 then x^0 is 1 and since -1^4 is -1 that gives you -1+1=0

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 perimeter of the patio is 64 feet. The width of the patio is (x+2) feet and the length of the patio is (x+6) feet. What are
ValentinkaMS [17]

The formula for the perimeter is P = 2<em>w</em> + 2<em>l</em>, where <em>w</em> is the width and <em>l</em> is the length. It is given that the width = (x+2) and the length = (x+6). Therefore, we can make this equation:

P = 2<em>w</em> + 2<em>l</em>

64 = 2(x+2) + 2(x+6) ⇒ Distributive property

⇒ 64 = 2x + 4 + 2x + 12 ⇒ Combine like terms

⇒ 64 = 4x + 16 ⇒ Subtract 16 from both sides

⇒ 48 = 4x ⇒ Divide both sides by 4

⇒ x = 12

Then, we use x = 12 and substitute it in to find the length and width

<em>Width</em> = (x+2) = (12+2) = 14

<em>Length</em> = (x+6) = (12+6) = 18

The dimensions of the patio is <u>14 by 18</u>
