Answer:
Explanation:
Bimetallic strips are used in thermostats for measuring and controlling temperature. The strip is connected to a switch and as the temperature changes, the strip flexes and opens or closes a contact. They are also used in ovens for measuring temperature. An electromechanical thermostat typically contains either a bi-metal coil or a metal strip. When the temperature changes, this coil or strip will move, causing a vial containing mercury to tip to one side. The mercury flows to one end of the vial, signaling that the heating or cooling needs to be turned on.
The period of the pendulum is given by the following equation
T = 2π * sqrt (L/g)
Where g is the gravity (free fall acceleration)
L is the longitude of the pendulum
T is the period.
We find g.............> (T /2π)^2 = L/g
g = L/(T /2π)^2...........> g = 22.657 m/s^2
