Answer: true
Explanation:
it flows faster over the top of the wing because the top is more curved than the bottom of the wing. However
78950W the answer
Explanation:
A 75- kw, 3-, Y- connected, 50-Hz 440- V cylindrical synchronous motor operates at rated condition with 0.8 p.f leading. the motor efficiency excluding field and stator losses, is 95%and X=2.5ohms. calculate the mechanical power developed, the Armature current, back e.m.f, power angle and maximum or pull out torque of the motor

Answer:
(d) a and c are correct
Explanation:
METALS : Metal are those materials which has very high ductility, high modulus of elasticity, good thermal and electrical conductivity
for example : iron, gold ,silver, copper
ALLOYS: Alloys are those materials which are made up of combining of two or more than two metals these also have good thermal and electrical conductivity and me liable property
for example ; bronze and brass
so from above discussion it is clear that option (d) will be the correct option
Answer:
14.36((14MPa) approximately
Explanation:
In this question, we are asked to calculate the stress tightened in a bolt to a stress of 69MPa.

def calculate_pay(total_worked_hours, rate_per_hour):
if total_hours_worked > 40:
# anything over 40 hours earns the overtime rate
overtimeRate = 2 * rate
_per_hour
return (40 * rate_per_hour) + ((total_worked_hours - 40) * overtimeRate
else:
# if you didn't work over 40 hours, there is no overtime
overtime = 0
return total_worked_hours * rate_per_hour
Explanation:
- First we create the calculate_pay function which will takes 2 parameters.
- Secondly ,inside the function we check if the total_worked_hours is greater than 40 and then return the pay by calculating with the help of formula for work over 40 hours.
- If the total work hour is less than 40 then we return the pay by multiplying the total_worked_hours with rate_per_hour.
