Explanation:
volume = πR²h/3
= πx35²x50/3
= 192325/3
= 64166.725
number of layers n = 50mm/0.05
n = 1000layers
average volume = 64166.725/1000
= 64.167mm³
average area = 64.167/0.05
= 1283.34mm²
average time = 1283.34/900mm x 0.22
= 6.48
6.48 + 15 seconds
= 21.48 seconds
time required = 1000x21.48
= 21480 seconds
convert to minutes
21480/60
= 358 minutes
21480/3600
= 5.967 hours
Answer:
B. 26 rpm
Explanation:
The sprocket has a diameter of 10 in
The back wheel has a diameter of 6.5 in
One complete revolution formula is : 2πr -------where r is radius
For the sprocket , one revolution = π * D where D=2r
π * 10 = 31.4 in
For the back wheel, one revolution = π* 6.5 = 20.42 in
The pedaling rate is : 40 rpm
Finding the ratio of revolutions between the sprocket and the back tire.
In one revolution; the sprocket covers 31.4 in while the back tire covers 20.42 in so the ratio is;
20.42/ 31.4 = 0.65
So if the speed in the sprocket is 40 rpm then that in the back tire will be;
40 * 0.65 = 26 rpm
There are different kinds of care given to machine parts. Technician A says that a pilot bearing should always be replaced when a clutch is replaced is a true statement and thus is the only correct one.
<h3>When should I replace my pilot bearing?</h3>
- If one notice vibration on the clutch pedal, it is shows that it is worn-out bearing and thus needs changing.
Most times, pilot bearing is often replaced as kind of precautionary measure that is taken when clutch is replaced.
Torsional vibrations are said to be vibrations due to firing force twisting and accelerating of the crankshafts when a cylinder fires and cannot be absorbed by oft-dampened clutches.

Answer:
# string_contains function is defined with input_string
# as arguments
def string_contains(input_string):
# if-statement that check if letter z is in input_string
if 'z' in input_string:
# it print"has the letter z" if it has z
print("has the letter z")
else:
# else it print "not worthwhile"
print("not worthwhile")
# string_contains function is called
string_contains("The animal is zebra")
string_contains("learning is fun")
Explanation:
The code is written in Python and well commented.
