Answer:
The energy source that does not use heat in the process of converting it to electricity is;
c. Sunlight
Explanation:
In converting Sunlight energy source to electricity, the photons in the light from the Sun excite electrons in the solar cells silicon layers, such that the electrons travel from n-type silicon layer to the p-type silicon layer creating electric potential energy that does work as the electrons flow back in the form of electricity from the p-type to the n-type silicon layer through an external circuit
Answer:
def newton(n):
#Define the variables.
t = 0.000001
esti = 1.0
#Calculate the square root
#using newton method.
while True:
esti = (esti + n / esti) / 2
dif = abs(n - esti ** 2)
if dif <= t:
break
#Return the result.
return esti
#Define the main function.
def main():
#Continue until user press enters.
while True:
try:
#Prompt the user for input.
n = int(input("Enter a number (Press Enter to stop):"))
#display the results.
print("newton = %0.15f" % newton(n))
except:
return
#Call the main function.
main()
(Disclaimer: I am not a professional, so it might not be the most concise answer possible, but I did run the Python script and it works)
Answer:
user_input = input("What food do you have in your refrigerator? ").lower()
count = 0
while True:
if user_input != 'apples':
count += 1
print(f'You have a {user_input} with a total of {count} food(s)\n')
user_input = input("What food do you have in your refrigerator? ")
else:
break
