The ant repeats the two steps 7times, going around the polygon until it reaches its starting position. The ant makes a complete revolution(360) to draw this regular 7-sided polygon The value of A, correct to 1decimal place is

An ant starts from the top rim of the cylinder section of a pipe and reaches a point directly below its starting point after making three complete revolutions around the pipe.The distance traveled by the ant if the height of the cylinder is 24cm and radius of the pipe is cm (3)/(pi) is :

A positive charge +q_1 is located to the left of a negative charge -q_2 . On a line passing through the two charges, there are two places where the total potential is zero. The reference is assumed to be at infinity.The first place is between the charge and is 4.00 cm to the left of the negative charge. The second place is 7.00 cm to the right of the negative charge. If q_2 = -12muC and q_1 = 11 xx xmuC , what is the value of x.

Arrange the following steps of an experiment in a sequential order to determine the frequency of a simple pendulum. (A) Start the stop watch when the bob reaches the extreme position and count the number of oscillations.(B) Suspend a simple pendulum from a cork fixed to a stand. (C) Repeat the experiment and determine the time taken for 20 oscillations. (t_(2)) (D) Pull the bob of the simple pendulum from its initial position of rest and release. (E) Stop the stop watch at the end of 20 oscillations and determine the time taken to complete 20 oscillations (t_(1)) . (F) Determine the average of t_(1) and t_(2) as t. (G) The time period of the oscillation is found using. T = (t)/(20) and frequency using, f = 1/T .
