What is spherical wave example? One common example of a spherical wave is a sound wave. When an object oscillates or vibrates in the presence of medium, a sound wave is produced and this wave propagates outward in all possible directions. As the wave travels outward, it carries energy. How do you make spherical waves? […]
Do we eat sunlight?
Do we eat sunlight? Yes, definitely. Almost all living things on earth are fueled by the sun either directly or indirectly. (The exception is organisms that live near volcanic vents deep in the ocean.) Energy from the sun is taken in by plants and eaten by animals. Do humans get energy directly from the sun? […]
What does a negative angular acceleration indicate to you?
What does a negative angular acceleration indicate to you? Negative angular velocity(ω) means that the particle is revolving anticlockwise. Thus, negative angular acceleration(α) is a “push” in the anticlockwise direction. If α and ω have the same sign, the body will speed up, else slow down (and eventually go in reverse). Is clockwise positive or […]

This value for local, trafficking, railway track laying and maneuvering trains is 7.92 L/km. Why do trains have wires above them? In our world, a catenary is a system […]
What is the formula for calculating efficiency?
What is the formula for calculating efficiency? The formula to calculate work efficiency is the ratio of output to input expressed as a percentage. The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. How do you calculate the maximum […]
Do brain tumors cause ear pain?
Do brain tumors cause ear pain? Although these tumors are benign, they can cause serious complications and even death if they grow and exert pressure on nerves and eventually on the brain.

Which position is safe for always keep the cylinder? Always keep the cylinders in a vertical position with the valve on top. If cylinder is placed in any other position, liquid LPG may gush out of the open valve creating a dangerous situation. Cylinders must be installed at ground level and never below ground level […]
How is electrophoresis used in medicine today?
How is electrophoresis used in medicine today? Electrophoresis is used to separate the antibodies in the antibiotic from any impurities. This process also enables researchers to determine the concentration of the antibiotic, making dosage more accurate. DNA analysis: DNA analysis is one of the most common applications for electrophoresis. What information does gel electrophoresis provide? […]
