Can you further elaborate this isn't making much sense my mans
Answer:
422.36 N
Explanation:
given,
time of rotation = 4.30 s
T = 4.30 s
Assuming the diameter of the ring equal to 16 m
radius, R = 8 m


v = 11.69 m/s
now, Force does the ring push on her at the top





N = 422.36 N
The force exerted by the ring to push her is equal to 422.36 N.
Answer:
I think the answer to your question is true
Answer:
0.033815 m/s²
12.48810875 m
Explanation:
t = Time taken = 12 s
= Final angular velocity = 95 rpm
= Initial angular velocity = 64 rpm
= Angular acceleration
= Angle of rotation

Tangential acceleration is given by

The tangential acceleration of the pedal is 0.033815 m/s²

Linear displacement would be 
Length of chain that passes in the interval is 12.48810875 m
Answer:
The magnitude of force per unit length of one wire on the other is
and the direction is away from one another
The magnitude of force per unit length of one wire on the other is
and the direction is towards each other.
Explanation:
= Vacuum permeability = 
= Current in first wire = 2.9 A
= Current in second wire = 5.3 A
r = Gap between the wires = 11 cm
Force per unit length

The magnitude of force per unit length of one wire on the other is
and the direction is away from one another

The magnitude of force per unit length of one wire on the other is
and the direction is towards each other.
