Answer:
A.
The power generated by a wind farm is not constant because of irregular wind patterns.
Answer:
The answer is "
and 157.5 MPa".
Explanation:
In point A:
The strength of its products with both the grain dimension is linked to this problem. This formula also for grain diameter of 310 MPA is represented as its low yield point
Here y is MPa is low yield point, x is mm grain size, and k becomes proportionality constant.
Replacing the equation for each condition:
People can get yo = 275 MPa with both equations and k= 15.5 Mpa 
.
To substitute the answer,
In point b:
The equation is 
equation is:
by putting the above value in the formula we get the 
value that is= 157.5 MPa
Answer:
the rate of increase of radius is dR/dt = 0.804 m/hour = 80.4 cm/hour
Explanation:
the slick of oil can be modelled as a cylinder of radius R and thickness h, therefore the volume V is
V = πR² * h
thus
h = V / (πR²)
Considering that the volume of the slick remains constant, the rate of change of radius will be
dh/dt = V d[1/(πR²)]/dt
dh/dt = (V/π) (-2)/R³ *dR/dt
therefore
dR/dt = (-dh/dt)* (R³/2) * (π/V)
where dR/dt = rate of increase of the radius , (-dh/dt)= rate of decrease of thickness
when the radius is R=8 m , dR/dt is
dR/dt = (-dh/dt)* (R³/2) * (π/V) = 0.1 cm/hour *(8m)³/2 * π/1m³ *(1m/100 cm)= 0.804 m/hour = 80.4 cm/hour
Answer:
c. Detail designation
Explanation:
the question "enlarged detail to show more information", That has a detail indicator area circle. It's usually more of a square or rectangle not a circle. Circles are good for detailing landscape.
"They also can indicate when a section of the house is being enlarged." Sections details use that symbol but have a section indicator line. Also grid and column indicators use that symbol.
Answer:
D
Explanation: you need a jump cable to hook on a power source because the jump cable has two color cables to hook up to the power source. the two jump cables have two colors to tell you which one is positive and negative. The red one is the positive and the black on is the negative one.
