Which of the following is conserved in inelastic collision?
Which of the following is conserved in inelastic collision? An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been transferred to something else. Which one of the […]

How far can electricity be transmitted efficiently?
How far can electricity be transmitted efficiently? As of 1980, the longest cost-effective distance for direct-current transmission was determined to be 7,000 kilometres (4,300 miles). For alternating current it was 4,000 kilometres (2,500 miles), though all transmission lines in use today are substantially shorter than this. What are the three parts of the electrical system? […]

How can you increase the efficiency of a solar collector?
How can you increase the efficiency of a solar collector? The radiations coming from the sun’s energy were converted into heat, and then this heat was transferred to the collector fluid, water. A prototype of a solar water heating system was constructed and obtained the improvement of the collector efficiency around 10% by using the […]
