A 53 kg gymnast applies a vertical ground reaction force of 1,080 N at 0.13 m behind the center of mass during a forward somersault. Assume she is facing the right. What is the torque generated about the center of mass

Torque is 140.4 N-m.

Explanation:

Mass of the gymnast, m = 53 kg

Vertical force acting on the gymnast, F = 1080 N

Distance, r = 0.13 m behind the center of mass during a forward somersault. We need to find the torque generated about the center of mass. The force is acting behind the center of mass. F = -1080 N

Torque is given by :

So, the torque generated about the center of mass is 140.4 N-m.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
