Let's say you have a plot for pendulum experiment. let's assume g for this experiment was measured (from the slope of the plot) to be 9.78 [ms^-2]. the vertical intercept, however, is 0.021 [s^2]. what might this translate to for a measurement of the length offset systematic in all the length measurements? length offset =[mm] .011

The length is 5.2 mm.

Explanation:

Given that,

Time period T²= 0.021 s²

Gravity due to acceleration = 9.78 m/s²

We need to calculate the length

Using formula of time period of pendulum

Where, l = length

g = acceleration due to gravity

T = time period

Put the value into the formula

Hence, The length is 5.2 mm.

it is a negative acceleration
