Final answer:
To determine the acceleration due to gravity at a new location, we need to know the length and period of the pendulum.
Step-by-step explanation:
The acceleration due to gravity can be determined using the formula for the period of a pendulum, T, which is the time it takes for the pendulum to complete one full swing. The formula is T = 2π√(l/g), where l is the length of the pendulum and g is the acceleration due to gravity. By rearranging the formula, we can solve for g: g = 4π²(l/T²).
To find the acceleration due to gravity at the new location where the period is 1.99796 s, we need to plug in the values of l and T from the given information. However, the values for l and T are not provided in the question, so we cannot determine the acceleration due to gravity at the new location without that information.
