and the weighted pen moves back and forth due to the motion of seismic waves. the pen records the movement on the drum. the paper recording of an earthquake is called a seismogram. a seismograph is securely mounted onto the surface of the earth. except for the mass on the spring, the ...
ohm’s law types of potentiometer there are basically two types of potentiometers that can be further divided depending on the movement of the wiper. following is the table when the wiper is moving in a circular path which is known as rotary potentiometer. type description applications concentric...
, which consists of a cathode, an anode, and an electrolyte. in these cells, the electrolyte enables the movement of the protons. recommended videos working of fuel cell the reaction between hydrogen and oxygen can be used to generate electricity via a fuel cell. such a cell was used in ...
in the course of movement, the frictional force acts in the direction opposite to the force applied. this allows the body to move in the forward direction with minimum resistance. as the axle is fixed to the wheel, it behaves as a fulcrum. the friction that is generated between the axle ...
the process of movement of solvent through a semipermeable membrane from the solution to the pure solvent by applying excess pressure on the solution side is called reverse osmosis . reverse osmosis is a membrane treatment process primarily used to separate dissolved solutes from water. reverse...
