Answer:

Explanation:
#First, we need to determine the actual emf required. The generator's internal resistance will cause a voltage drop inside the generator/
Internal resistance is defined using the formula:

#The bulb is rated 12.0V,25.0W
Current, 
Therefore, the voltage drop in the generator is calculated as:
Actual EMF required is thus 1.536V+12.0V=13.536V
#peak voltage is 
#For a generator, by Faraday's Law


#The rate of the generator is 25.39Hz

11
Explanation:
There are 2.2lbs in a kilo
times the KG by 2.2 and u get the amount in lbs (pounds)
Answer: Option (b) is correct.
Explanation:
Since we know that,
P = VI
where;
P = power
V= Voltage
I = Current
Since it's given that,
P = 600W
I = 2.5 A
equating these values in the above equation, we get;
<em>V =
</em>
<em>V = 240 V</em>
Answer:

31.29 m/sec
Explanation:
We have given density of substance 
We have convert this into
We know that 1 lb = 0.4535 kg. so 0.14 lb = 0.14×0.4535 = 0.06349 kg
We know that 1 kg = 1000 g ( 1000 gram )
So 0.06349 kg = 63.49 gram
And we know that 1 gram = 1000 milligram
So 63.49 gram 
We know that 
So 
So
=\frac{63.49\times 10^3}{0.2249\times 10^{-5}}=276.74\times 10^8lb/m^3[/tex]
In second part we have to convert 70 mi/hr to m/sec
We know that 1 mi = 1609.34 meter
So 70 mi = 70×1609.34 = 112653.8 meter
1 hour = 3600 sec
So 70 mi/hr
