### How to Convert Milliammeter Into Voltmeter and Ammeter

Ohm’s law enables us to use a milliammeter as a voltmeter. Let us suppose that we have a moving – coil instrument which requires 5…

### Definition of Graham’s Law and Explanations of Thermal Agitations

What are Thermal Agitations? When a gas passes through a porous plug, a cotton-wool wad, for example, it is said to diffuse’. In that it…

### Application and Uses of Bunsen’s Ice Calorimeter

The Bunsen’s ice calorimeter is a device for measuring a quality of heat by using it to melt ice. When ice turns to water, it…

### Calorimetry and the Application of Newton’s Law of Cooling

Newton’s Law of Cooling: Newton was the first person to investigate the heat lost by a body in air. He found that the rate of…

### Applications of Ostwald Viscometer and Stoke’s Law of Terminal Velocity

An Ostwald Viscometer, which contains a vertical capillary tube T, is widely use for comparing the viscosities of two liquids. The liquid is introduced at…

### Turbulent Motion and Explanations by Poiseuille’s Formula

Poiseuille’s Formula holds as long as the velocity of each layer of the liquid is parallel to the axis of the pipe and the flow…

### What is Viscosity? Application of Viscosity to Fluid Mechanics

If we move through a pool of water we experience a resistance to our motion. This shows that there is a frictional force in liquids….

### Applications of the theory of Solid, Static and Kinetic Friction

When a person walks along a road, he or she is prevented from slipping by the force of friction at the ground. In the absence…

### How to Determine the Dimension and Magnitude of Young’s Modulus

A modulus of elasticity of the wire, called Young’s modulus (E), is defined as the ratio           It should be noted…

### Definition and Application of Hooke’s Law of Elasticity

In understanding Hooke’s law, we can advance an illustration: A bridge, when used by traffic during the day, is subjected to loads of varying magnitude….
