Question

a pendulum was constructed and two different materials were tested for the weight at the end of the pendulum string. question: is there greater variation in \time for ball to move distance\ with the stainless steel ball trials or with the acrylic ball trials? greater variation with acrylic because the time variation in trials is 2.08 seconds. greater variation with stainless steel because the time variation in trials is 1.53 seconds. greater variation with stainless steel because the time variation in trials is 1.53 minutes. greater variation with acrylic because the time variation in trials is 2.05 seconds.

Explanation:

Step1: Find time variation for stainless - steel

For stainless - steel, the times are 6.16 s, 5.00 s, and 6.53 s. The maximum time is 6.53 s and the minimum time is 5.00 s. The time variation is $6.53 - 5.00=1.53$ s.

Step2: Find time variation for acrylic

For acrylic, the times are 11.55 s, 10.47 s, and 10.50 s. The maximum time is 11.55 s and the minimum time is 10.47 s. The time variation is $11.55 - 10.47 = 1.08$ s.

Step3: Compare variations

Since $1.53>1.08$, there is a greater variation with stainless - steel.

Answer:

Greater variation with stainless steel because the time variation in trials is 1.53 seconds.
