Answer:
$958.25
Explanation:
PV = FV(1 +r)^(-t) . . . . present value of an amount earning rate r compounded annually for t years
PV = $3000(1.08^-5) ≈ $2041.75
The equivalent present value is $2041.75.
__
This amount is less than the offered amount by ...
$3000 -2041.75 = $958.25
She should pay you $958.25 less in order to make the offers equivalent.
Answer:
Ammeters must always be connected in series with the circuit under test. Always start with the highest range of an ammeter. Deenergize and discharge the circuit completely before you connect or disconnect the ammeter. In dc ammeters, observe the proper circuit polarity to prevent the meter from being damaged.
Explanation:
Answer:
428°F
Explanation:
The equation to convert degrees Celsius to degrees fahrenheit is
°F (degrees fahrenheit) = (9/5 * °C (degrees celsius) ) + 32
°F = (9/5 * 220 °C (degrees celsius)) +32 = 428 °F (degrees fahrenheit)
Answer:
<em>screw thrust = ML</em>
<em> </em>
Explanation:
thrust of a screw propeller is given by the equation = p
x
Re
where,
D is diameter
V is the fluid velocity
p is the fluid density
N is the angular speed of the screw in revolution per second
Re is the Reynolds number which is equal to puD/μ
where p is the fluid density
u is the fluid velocity, and
μ is the fluid viscosity = kg/m.s = M

<em>Reynolds number is dimensionless so it cancels out</em>
The dimensions of the variables are shown below in MLT
diameter is m = L
speed is in m/s = L
fluid density is in kg/
= M
N is in rad/s = L
=
If we substitute these dimensions in their respective places in the equation, we get
thrust = M



= M


<em>screw thrust = ML</em>
<em> </em>
This is the dimension for a force which indicates that thrust is a type of force
Answer:
4.13 MPa
Explanation:
Given
Modulus of elasticity = E = 102 GPa
E = 102 * 10^9
Modulus resilience U = 0.79 * 106Pa
Modulus of Resilience U = y²/2E --- Make y the subject of formula
y² = 2EU
y = √(2EU)
y = √(2 * 102 * 10^9 * 0.79 * 106)
y = √1.708296E13
y = 4133153.759540044
y = 4.13E6
y = 4.13MPa
