Answer:

Explanation:
In electrical terms, is the ratio of time in which a load or circuit is ON compared to the time in which the load or circuit is OFF.
The duty cycle or power cycle, is expressed as a percentage of the activation time. For example, a 70% duty cycle is a signal that 70% of the time is activated and the other 30% disabled. Its equation can be expressed as:

Where:



Here is a picture that will help you understand these concepts.
Answer:
Numbers 4, 6, & 7 are correct
Explanation:
4- this allows the op amp to have zero voltage so that maximum voltage is transferred to output load.
6- this ensures that op amp doesn't cause loading in the original circuit, high input impedance would not deter the circuit from pulling current from it.
7- high difference between upper and lower frequencies.
Answer: P = I2R = 0.032 x 1000 =0.9 W
Explanation: The power will be the product of the square of the current and
the resistance of the load. The fact that the circuit is a parallel circuit is irrelevant to this question.
Answer:
<em>Python code is as follows:

print("Enter the price: ", end='', flush=True) #prompt for the input of price

totalCost = price + 0.05 * price #calculating cost
print("Total Cost after the sales tax of 5% is applied: " + toFixed(totalCost,2)) #print and output totalCost
