Everything wrong with 2020 is WW3 that dump trump decided to start , Australia fires , Kobe passed away than Pop smoke :( corona virus got really big , quarantine started , riots & protesting started because of that dumb who’re racist cop ! Hope this helps
Answer:
Net efficiency of generating unit = 42.08 - 5 = 37.08 %
Explanation:
We have given that efficiency of the boiler = 91.2 % = 0.912
Carnot efficiency = 46.9 % = 0.469
Efficiency of generator = 98.4% =0.984
We have to find the efficiency of total generating unit
For finding the efficiency of total generating unit we have to multiply all the efficiencies
So efficiency of generating unit = 0.912×0.469×0.984 = 0.4208 = 42.08 %
For plant losses we have to subtract 5%
So net efficiency of generating unit = 42.08 - 5 = 37.08 %
Answer:
165 mm
Explanation:
The mass on the piston will apply a pressure on the oil. This is:
p = f / A
The force is the weight of the mass
f = m * a
Where a in the acceleration of gravity
A is the area of the piston
A = π/4 * D1^2
Then:
p = m * a / (π/4 * D1^2)
The height the oil will raise is the heignt of a colum that would create that same pressure at its base:
p = f / A
The weight of the column is:
f = m * a
The mass of the column is its volume multiplied by its specific gravity
m = V * S
The volume is the base are by the height
V = A * h
Then:
p = A * h * S * a / A
We cancel the areas:
p = h * S * a
Now we equate the pressures form the piston and the pil column:
m * a / (π/4 * D1^2) = h * S * a
We simplify the acceleration of gravity
m / (π/4 * D1^2) = h * S
Rearranging:
h = m / (π/4 * D1^2 * S)
Now, h is the heigth above the interface between the piston and the oil, this is at h1 = 42 mm. The total height is
h2 = h + h1
h2 = h1 + m / (π/4 * D1^2 * S)
h2 = 0.042 + 10 / (π/4 * 0.14^2 * 0.8) = 0.165 m = 165 mm
Answer:
The correct answer will be "400.4 N". The further explanation is given below.
Explanation:
The given values are:
Mass of truck,
m = 600 kg
g = 9.8 m/s²
On equating torques at the point O,
⇒
So that,
On putting the values, we get
⇒ 
⇒ 
Flip-flops are normally used for all of the following applications, except logic gates.
<h3>What are Flip flops?</h3>
Flip flops are known to be tools that are used for counting. They come in different ranges.
Note that Flip flops are one that can be seen on counters, storage registers, and others and as such, Flip-flops are normally used for all of the following applications, except logic gates.
