For simple pendulum the formula is

Where T is time period , l is length and g is acceleration due to gravity .

n is frequency
Putting the values


l = 1.584 m
<h2>
Time taken by dryer to come up to speed is 1.625 seconds.</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 0 rad/s
Final velocity, v = 5.2 rad/s
Time, t = ?
Acceleration, a = 3.2 rad/s²
Substituting
v = u + at
5.2 = 0 + 3.2 x t
t = 1.625 s
Time taken by dryer to come up to speed is 1.625 seconds.
Answer:

Explanation:
The problem tell us that the temperature as function of time in downtown mathville is given by:

The average temperature over a given interval can be calculated as:

Where:

So, the initial temperature in this case, would be the temperature at noon, and the final temperature would be the temperature at midnight:
Therefore:


Hence, the average temperature between noon and midnight is:
