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:
D. Inspecting the muffler
Explanation:
HVAC/refigeration systems are sealed systems that use refrigerant not combustion. A muffler is found on combustion systems.
You would disconnect, flush, seal, and possibly replace the condenser if the condenser is found to be failing.
Answer:
E=23,976 J
Explanation:
Given that
I = 1.8 Ah
Voltage = 3.7 V
We know that 1 h = 3600 s
I = 1.8 x 3600 A.s
I=6480 A.s
The energy in Jules given as
E= V. I
We know that unit of V.I is Watts ( J/s) and when multiple by seconds then we get Joules.
E=3.7 x 6480 Watt.s
E=23,976 J
Therefore the energy in joule will be 23,976 J.
