Answer:
The code is given below in python
# Code Block 1
count = 0 # count variable
total = 0 # total variable
enter = '' # input variable
while enter != 'stop':
enter = input('Enter a grade:' )
if enter != 'stop' and enter.isdigit():
total += int(enter) # add to total value
count = count + 1 # then to the count
print float(total) / count
# Code Block 2
numbers = []
while enter != 'stop':
enter = input('Enter a grade:' )
if enter != 'stop':
numbers.append(int(enter))
print sum(numbers) / float(len(numbers))
Answer:
T = 5416.67 N
T = -2083.5 N
T = 0
Explanation:
Forward thrust has positive values and reverse thrust has negative values.
part a
Flight speed u = ( 150 km / h ) / 3.6 = 41.67 km / s
The thrust force represents the horizontal or x-component of momentum equation:

Answer: The thrust force T = 5416.67 N
part b
Now the exhaust velocity is now vertical due to reverse thrust application, then it has a zero horizontal component, thus thrust equation is:

Answer: The thrust force T = -2083.5 N reverse direction
part c
Now the exhaust velocity and flight velocity is zero, then it has a zero horizontal component, thus thrust is also zero as there is no difference in two velocities in x direction.
Answer: T = 0 N
Answer:
yes i have 2 huge bins of it
Explanation:
Because of the skin depth effect, the current at high frequency tends to flow at very low depth from radius. Then at high frequency the effective cross section of the wire is narrower than at DC.
Fro example skin depth at 100 kHz is 0.206 mm (0.008”), a wire more thicker than AWG26 could be a waste of copper, better use a bunch of thin wire (Litz wire) to rise the Q factor.
