The function below takes two numeric parameters. The first parameter specifies the number of hours a person worked and the secon

Mekhanik [1.2K]

def calculate_pay(total_worked_hours, rate_per_hour):

if total_hours_worked > 40:

# anything over 40 hours earns the overtime rate

overtimeRate = 2 * rate _per_hour

return (40 * rate_per_hour) + ((total_worked_hours - 40) * overtimeRate

else:

# if you didn't work over 40 hours, there is no overtime

overtime = 0

return total_worked_hours * rate_per_hour

Explanation:

First we create the calculate_pay function which will takes 2 parameters.

Secondly ,inside the function we check if the total_worked_hours is greater than 40 and then return the pay by calculating with the help of formula for work over 40 hours.
If the total work hour is less than 40 then we return the pay by multiplying the total_worked_hours with rate_per_hour.

(a) The reverse-saturation current of a pn junction diode is IS = 10−11 A. Determine the diode voltage to produce currents of (i

kirill115 [55]

Answer:

The equation used to solve a diode is

$i_d = I_se^\frac{V_d}{V_T}-1$

$i_d$ is the current going through the diode
$I_s$ is your saturation current
$V_D$ is the voltage across your diode
$V_T$ is the voltage of the diode at a certain room temperature. by default, you always use $V_T=25.9mV$ for room temperature.

If you look at the equation, $i_d = I_se^\frac{V_d}{V_T}-1$ , you'd notice that the $e^\frac{V_d}{V_T}$ grow exponentially fast, so we can ignore the -1 in the equation because it's so small compared to the exponential.

$i_d = I_se^\frac{V_d}{V_T}-1$

$i_d\approx I_se^\frac{V_d}{V_T}$

Therefore, use $i_d= I_se^\frac{V_d}{V_T}$ to solve your equation.

Rearrange your equation to solve for $V_D$ .

$V_D=V_Tln(\frac{i_D}{I_s})$

a.)

i.)

You're given $I_s=10^{-11}A$

at $i_d=10\mu A$ , $V_D=V_Tln(\frac{i_D}{I_s})=(25.9\cdot10^{-3})ln(\frac{10\cdot10^{-6}}{10\cdot10^{-11}})=.298V$

at $i_d=100\mu A$ , $V_D=V_Tln(\frac{i_D}{I_s})=(25.9\cdot10^{-3})ln(\frac{100\cdot10^{-6}}{10\cdot10^{-11}})=.358V$

at $i_d=1mA$ , $V_D=V_Tln(\frac{i_D}{I_s})=(25.9\cdot10^{-3})ln(\frac{1\cdot10^{-3}}{10\cdot10^{-11}})=.417V$

<em>note: always use</em> $V_T=25.9mV$

ii.)

Just repeat part (i) but change to $I_s=-5\cdot10^{-12}A$

b.)

same process as part A. You do the rest of the problem by yourself.

What is ventilation system on a boat for

Gemiola [76]

Answer:

Ventilation systems are crucial. Their purpose is to avoid explosions by removing flammable gases. The Small Vessel Regulations require that all gasoline-powered boats, constructed in a way that would entrap vapours, must have at least two ventilation ducts fitted with cowls to remove the vapours. ...
