1 kilo-calorie= 4184 joules
0.001 kilo-calorie= 1 calorie
therefore 5.25 calorie=21.966 joules
Answer:
2.36 μ H
Explanation:
Given,
Number of turns= 90
diameter = 1.3 cm = 0.013 m
unscratched length = 57 cm = 0.57 m
Area, A = π r²
= π x 0.0065² = 1.32 x 10⁻⁴ m²
we know,
L = 2.36 μ H
Hence, the inductance of the unstretched cord is equal to 2.36 μ H
Answer:
If she bends forward
Explanation:
because the equilibrium of gravity will not stay the same causing her to move forward
A force is a Vector quantity.
Which means it has both size or magnitude and with direction.
The calculation for power is
P = E / t
Where E is total energy transfered and t is time.
Now just substitute the number in
Power = 60 / 3
= 20W
The answer is 20W
