Why does the speedometer of a car read instantaneous speed? The speedometer of a car read the instantaneous speed not the average speed. We know that average speed is the ratio of total distance to the total time.It changes during when the car is moving . What does the speedometer of the car measure? Speedometer, […]
What is the concept of black body?
What is the concept of black body? Blackbody, also spelled black body, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. What is the absorptive power of a black body? For a […]
What are the disadvantages of carbon Fibre?
What are the disadvantages of carbon Fibre? Carbon fiber will break or shatter when it’s compressed, pushed beyond its strength capabilities or exposed to high impact. It will crack if hit by a hammer. Machining and holes can also create weak areas that may increase its likelihood of breaking. Can carbon fiber stop a bullet? […]

How do you measure high temperature?
How do you measure high temperature? Pyrometer, device for measuring relatively high temperatures, such as are encountered in furnaces. Most pyrometers work by measuring radiation from the body whose temperature is to be measured. How do you measure temperature over 100 degrees? Fahrenheit and Celsius are two different scales for measuring temperature. A thermometer measuring […]
What happens when things are heated differently?
What happens when things are heated differently? When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object […]
