Answer:
0.888 ohm
Explanation:
We have given that the battery has an emf of 12 volt that E =12 volt
Terminal voltage V =18.4 volt
Current through the battery is =7.20 A
We have top find the internal resistance of the battery
Now according to Kirchhoff's law V=E+IR
So 
So the value of internal resistance of battery is 0.888 ohm
Answer: Torque T = 40.7 Nm
Explanation:
Torque or turning effect is the rotational equivalent of linear force, i.e moment of force about a point.
Given that the force is applied perpendicular to the edge (angle 90°)
Torque can be represented by T;
T = FrSin∅ = Fr ( sin90 = 1)
T = force × distance
T = F × r
F = 55N
r = 74cm = 0.74m
T = 55N × 0.74m
T = 40.7 Nm
82 ÷ 6.5 = 12.615384615384... repeating
round = 12.6
12.6 · 6.5 = 81.9
round = 82
She went an average of 12.6 km an hour
Hope this helps! ;)
I am sitting in my seat.
I am listening to my mp3 and reading my book.
My eyes are getting heavy. They start to close.
I try to stay awake, but it's no use.
I am so warm and comfortable and sleepy,
and I have just finished my dinner.
Finally I can't help it. Resistance is futile.
I give up, and fall deep asleep.
My head rests back against my soft, comfy seat.
My seat is in row 26 on the airplane I'm flying in
to visit my grandmother on the coast.
We are cruising at 560 miles an hour, bearing 280°,
at flight level 320 .
The temperature outside my window is -60°F .
