Answer:
44.08 Volt
Explanation:
N = 8, A = 0.0775 m^2, R = 8.53 ohm, B = 0.222 T, f = 51 Hz
e0 = N B A w
e0 = 8 x 0.222 x 0.0775 x 2 x 3.14 x 51
e0 = 44.08 Volt
The ball dropped of a cliff will have a final velocity of 19.6 m/s at 2s
The free fall formula and the procedure we will use is:
fv = g* t
Where:
- fv = final velocity
- g = acceleration due to gravity
- t = time taken
- h = height traveled
Information of the problem:
- g = 9.8 m/s².
- t = 2 s
- vf = ?
Applying final velocity formula we get:
fv = g* t
fv = 9.8 m/s² * 2 s
fv = 19.6 m/s
<h3>What is free fall?</h3>
It is when the object or mobile falls from a height (h) with a positive acceleration equal to the gravity, describing a vertical rectilinear travel.

Answer:
The average speed is 3.5 mi/h
Explanation:
Average speed is given by

If the total distance covered is
mi,
Then
mi was covered while hiking and
mi was covered while running.
Now, we will find the time taken while hiking and the time taken while running

- For the time taken while hiking
Speed = 2.9 mi/h
Distance =
mi
From,


Time =
h
Time taken while hiking is 0.2299 h
- For the time taken while running
Speed = 5.6 mi/h
Distance =
mi


Time =
h
Now, for the average speed

Total distance =
mi +
mi =
mi
Total time =
+
=
h
∴ 
Average speed = 3.4552 mi/h
Average speed ≅ 3.5 mi/h
