Question

Take a ball or a stone and wrap some cloth around it. Now, tie it to the end of a thread of a definite length (say 1
metre) and hang it somewhere from the ceiling. This will be your little pendulum. Push it with considerable force
and measure the oscillation time period with your smartwatch. You can start by taking the period as 5 or 10
oscillations to avoid any mistake. Determine the value of g using the following formula.​

Answer 1

the science of numbers and their operations (see operation sense 5), interrelations, combinations, generalizations, and abstractions and of space (see space entry 1 sense 7) configurations and their structure, measurement, transformations, and generalizations Algebra, arithmetic, calculus, geometry

Answer 2

Tan C = AB/AC Suppose , AB= 100 and AC = 58, then Tan C = 1.724 You will get the value of C= 60 degrees
