    Ritcher scale is used to measure earthquakes

    0Thank You

    Palluu Verma🖤👑 2 years ago

    The Richter scale is a logarithmic scale that measures the magnitude of an earthquake. It uses the amplitude of the largest seismic wave to determine the earthquake's magnitude. The scale ranges from 1 to 10, with no upper limit. Because it's logarithmic, an earthquake rated as 5 is ten times as powerful as one rated as 4.

    Aim: To test whether a given liquid conducts electricity or not. Things required: A dry cell, pieces of copper wire, two iron nails, a rubber cork, a bulb fixed in a bulb holder, a beaker, lemon juice, vinegar, tap water, dilute hydrochloric acid, dilute potassium hydroxide, alcohol, kerosene and mustard oil. Method: 1. Take two iron nails and fix them on a rubber cork. 2. Take a beaker and place the rubber cork having the iron nails. Make a circuit by connecting a bulb, a switch, a cell using copper wire and iron nails. This is your electric tester. 3. Pour lemon juice in the beaker carefully. Now pass the electric current through the lemon juice by closing the switch. You observe that the bulb glows showing that lemon juice is a good conductor of electricity. 4. Repeat the activity one by one with other liquids. Wash, wipe and dry the ends of electric tester after testing each liquid.
