Are anode rays deflected by electric field? Anode rays are deflected by electric and magnetic fields but in a direction opposite to that of cathode rays. Why are they called cathode rays? Eugen Goldstein coined the term cathode rays in 1876. They were called cathode rays because they were emitted from the cathode of the […]
What is the cleanest burning fossil fuel?
What is the cleanest burning fossil fuel? natural gas What can fossil fuels be replaced with? According to the National Aeronautics and Space Administration (NASA), nuclear power is the most effective substitute to challenge fossil fuels for future energy consumption.

Who made the HR diagram?
Who made the HR diagram? Ejnar Hertzsprung What is the biggest difference between a star and a protostar? The fundamental difference between a protostar and a star is that the latter has nuclear fusion as its energy source and the former does not. The birth of stars is a battle between gravity and radiation pressure. […]

Where does the energy go when a ball bounces?
Where does the energy go when a ball bounces? When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. When it reaches Earth, it collides head-on with an incredibly massive object that is, from your perspective, at rest. The ball slows down, deforms temporarily and shoots back up. At what […]
