The generated emf when it is running as a generator= 238.16V
The generated emf as a motor taking 60A= 236.12V
<h3>Calculation of Electromotive force (emf)</h3>
The Resistance of the machine= 0.102
The connected voltage = 230V
The formula for emf; E= V +IR
The generated emf when it is running as a generator,
= 230 + (80*0.102)
= 230 + 8.16
= 238.16V
The generated emf as a motor taking 60A;
= 230 + (60 * 0.102)
= 230 + 6.12
= 236.12V

Answer:
Step-by-step explanation:
The response of this would be to say that those people without daytime jobs that are outside the home, are more likely to be home and thus, have more time on their hands to attempt to bake. So basically, the quoted 56% is definitely going to be higher than the population percentage.
Answer:
9 cars
Step-by-step explanation:
8 minutes = 3 cars
8 minutes x 3=24 minutes
3 cars x 3 = 9 cars
The standard deviation of the sampled containers contents is 0.50.
Option (b) is correct.
To find the standard deviation.
<h3>What is a standard deviation?</h3>
A standard deviation (or σ) exists as a measure of how dispersed the data exists about the mean. Low standard deviation means data exist clustered about the mean, and high standard deviation suggests data exist better extended out.
Given that:
Mean is the sum of all values divided by the total number of values.
Mean
= (1/10) [19.52+19.61+19.62+20.3+19.74+19.88+19.9+19.8+20.97+20.92]
= 200.26/10
= 20.02
s^2=1/10[(19.52-20.02)^2+(19.61-20.02)^2+(19.62-20.02)^2+(20.3-20.02)^2+(19.74-20.02)^2+(19.88-20.02)^2+(19.9-20.02)^2+(19.8-20.02)^2+(20.97-20.02)^2+(20.92-20.02)^2]
1/10*2.52
=0.25
![s=\sqrt{0.25}](https://tex.z-dn.net/?f=s%3D%5Csqrt%7B0.25%7D)
s=0.50
The standard deviation exists at 0.50293.
Therefore, the standard deviation of the sampled containers contents is 0.50.
