Answer:
Science is what makes up the wires, engineering is how that all works, technology is what the goal is, and math is how many of a component you have to put in it.
Explanation:
I am in an engineering class
Answer:
1.75 kW
$0.137 kWh
4.61 kW
$3.16 therm
Explanation:
Utilized power input of the burner is
P(ui) = total power input * efficiency
P(ui) = 2400 W * 0.73
P(ui) = 1752 W or 1.75 kW
Unit cost of utilized energy is
C(ui) = Unit cost of electricity/efficiency
C(ui) = $0.1 / 0.73 kWh
C(ui) = $0.137 kWh
Power input to the gas burner is
P(gi) = Utilized power input of the burner / efficiency of the burner
P(gi) = 1.75 / 0.38
P(gi) = 4.61 kW
Unit cost of utilized energy is
C(gi) = Unit cost of gas /efficiency
C(gi) = $1.2 / 0.38 kWh
C(gi) = $3.16 therm
Answer:
HB=131.69
Explanation:
Given that
Diameter , D= 10 mm
Depth of indentation ,d= 1.55 mm
Load ,P =500 kg
Brinell hardness is given as
Now by putting the values in the above equation we get
HB=131.69
Therefore the hardness of the material will be 131.69 HB.
Answer:
- TAX_RATE = 0.20
- STANDARD_DEDUCTION = 10000.0
- DEPENDENT_DEDUCTION = 3000.0
-
- # Request the inputs
- grossIncome = float(input("Enter the gross income: "))
- numDependents = int(input("Enter the number of dependents: "))
-
- # Compute the income tax
- taxableIncome = grossIncome - STANDARD_DEDUCTION - \
- DEPENDENT_DEDUCTION * numDependents
- incomeTax = taxableIncome * TAX_RATE
-
- # Display the income tax
- print("The income tax is $" + str(round(incomeTax,2)))
Explanation:
We can use round function to enable the program to output number with two digits of precision.
The round function will take two inputs, which is the value intended to be rounded and the number of digits of precision. If we set 2 as second input, the round function will round the incomeTax to two decimal places. The round function has to be enclosed within the str function so that the rounded value will be converted to a string and joined with the another string to display the complete a sentence of income tax info.
Answer:
pascals is this = 101352.972 Pa
Explanation:
given data
Atmosphere pressure at sea level = 14.7 lb/in²
we convert 1 Pa = 1 N/m² to lb/ft²
so we convert here 14.7 lb/in² to pascals
we know that 1 lb/ft² = 47.990172 N/m²
so
1 lb/ft² × ft²/(12in)² = 47.990172 × 144 N/m²
it will be simplyfy
1 lb/ft² = 6894.76 N/m²
so
14.7 lb/in² = 14.7 × 6894.76 N/m²
14.7 lb/in² = 101352.972 Pa
