Question

Monica takes 20 minutes from her house to reach her school on a bicycle. If the bicycle has a speed of 3m/s, calculate the distance between her house and the school in kilometers. (3.6 km)Can we tell frequency o to time period of pendulum. answer for brainliest marking .

Answer 1

Given:

Time Taken: 20 mins = 1200 seconds

Speed: 3m/s

Distance: x

Explanation:

$speed = \frac{distance}{time} \\ 3 =\frac{x}{1200}$

x = 3 x 1200

  = 3600 m

  = 3.6 km

The time taken by the pendulum to complete one oscillation is time period.

The no. of oscillations per unit time is frequency.
