Step-by-step explanation:
The pendulum swings over an angle of 2×(2°30') or 5° so we need to convert this to radian measure first:

so the arc length is given by

Answer:
с
) 20%
Step-by-step explanation:
There are 5 orange candies, and 25 total candies to choose from. If you only want to pick the orange candies, then the probability would be 5/25, or 1/5.
1/5, in percentage, is 20%.
The square root of 196 is 14
