Answer:
Gravitational Potential =58.914 KJ
Explanation:
We know that
Given mass = 251 kg
Height= 24 m
g is acceleration due to gravity =
Applying values in the equation we get
Net efficiency of generating unit = 42.08 - 5 = 37.08 %
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 %
using calculations Heat losses will be 4512 J
= Velocity of car = 65 mph =
= Density of air =
From Bernoulli's law we have
The maximum pressure on the girl's hand is
Now = 200 mph =
Option B
10,20,24,75,70,18,60,35
The first, second and third iteration of the loop will be as follows
insertion sort iteration 1: 20,24,10,75,70,18,60,35
insertion sort iteration 2:10,20,24,75,70,18,60,35
insertion sort iteration 3: 10,20,24,75,70,18,60,35
