What does WMAP measure? The Wilkinson Microwave Anisotropy Probe (WMAP) mission reveals conditions as they existed in the early universe by measuring the properties of the cosmic microwave background radiation over the full sky. This microwave radiation was released approximately 375,000 years after the birth of the universe. What is the significance of the small […]

What is the function of super heater in the boiler?
What is the function of super heater in the boiler? In a steam engine, the superheater re-heats the steam generated by the boiler, increasing its thermal energy and decreasing the likelihood that it will condense inside the engine. Superheaters increase the thermal efficiency of the steam engine, and have been widely adopted. How many methods […]
What causes drum brakes to drag?
What causes drum brakes to drag? Brake dragging is commonly caused by broken or weak springs on the drum brakes. It can also be due to a corroded or jammed caliper piston or a caliper that has corroded bushings or mounting pins.

How do you find the cross-sectional area of copper wire?
How do you find the cross-sectional area of copper wire? ρ=RAl. The cross-sectional area of the wire A is the area of a circle of radius r, or of diameter d = 2r: A=πr2=π(d2)2. How do you calculate cross-sectional resistance? resistivity = resistance × area / length b) A wire made of a copper alloy […]
