Answer:
Part a)
Part b)
Part c)
Part d)
Explanation:
Part a)
Since the gymnast is holding the rope and remains stationary
So total force is balanced on it
so we will have
T = mg
Part b)
Now gymnast start climbing the rope at uniform speed
so here we have
so again we will have same force equation
Part c)
Now gymnast start climbing up the rope at uniform acceleration
so now we will have
Part d)
Now gymnast start sliding downwards with same uniform acceleration
so now we will have
now we have
Answer:
<h3>Uniform polarization of the heart membranes</h3>
Explanation:
The maximum torque that can act on the loop is 7.875 N-m.
Torque:
Torque is a twisting or turning force that tends to cause rotation around an axis, which might be a center of mass or a fixed point. Torque can also be thought of as the ability of something that is rotating, such as a gear or a shaft, to overcome turning resistance.
The formula of torque:
Torque(T) = I B A
B = magnetic field of intensity
I = current =
A = area of the wire
l = length of the wire
l = 2πr
r = l/2π
A = πr²
= π(l/2π)²
= l²/4π
T = l²/4π IB
=( 1/4π) BIl²
= (1/4π) 0.30 × 150 ×× 2.20
= 7.875 N-m
Therefore the torque is 7.875 N-m.
