1. A simple pendulum has a period of 3.45 seconds. When the length of the pendulum is shortened by
1.0m, the period is 2.81 seconds, calculate:
a. the original length of the pendulum
b. the value of the acceleration due to gravity.

a

explanation:

because they are cartillidge

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:

there are no components of a physical goal mentioned on the list of choices that you've provided.

c) power lifting, will be your answer.
