A student is investigating the oscillations of the pendulum shown in the figure. The variables are• the length l of the pendulum• the mass m of the pendulum bob• the amplitude θ of the swing.The time taken for one complete oscillation is called the period T.She carries out three experiments. Each experiment investigates the effect on the period T ofchanging one variable. Her results are shown in the tables. Study the tables and choose the incorrect conclusion.*3 points

A 125 g pendulum bob hung on a string of length 35 cm has the same period as when the bob is hung from a spring and caused to oscillate. What is the spring constant?

ow is the time period of simple pendulum vary with its amplitude?

a) The period of a simple pendulum is T = 2𝜋L/g where L is the length of the pendulum and g is the acceleration due to gravity at the pendulum's location. Thus, if a pendulum has a period of T = 1.9 s on Earth where gEarth = 9.8 m/s2, its length isLEarth  =  gEarthT24𝜋2    =  m/s2 s 2 4𝜋2    =  m = cm

What is the period of a simple pendulum that is 1.13-m long in each situation?  In the physics lab

A simple pendulum is 5.00 m long. What is the period of small oscillations for this pendulum if it is located jn an elevator (a) at rest? (b) Accelerating upward at 5.00 m/s²? (c) Accelerating downward at 5.00 m/s²? (d) What is the period of this pendulum if it is placed in a truck that is accelerating horizontally at 5.00 m/s²?
