Is friction necessary for a body to roll? Yes friction is necessary to the body to roll. The minimum friction is that when the body moves easily by using 1 Newton of force. How is the draft calculated in rolling? Explanation: During rolling process, the workpiece gets squeezed, causing the thickness of the workpiece to […]

What happens if mass and velocity are doubled?
What happens if mass and velocity are doubled? Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum. What happens to the kinetic energy when the mass and velocity is […]
What happens to the volume of a gas when you double the number of moles of gas?
What happens to the volume of a gas when you double the number of moles of gas? Le Chatelier’s Principle states that: a) When a system at equilibrium is disturbed , a new equilibrium constant is established. What happens to the volume of gas when you double the number of moles of gas while keeping […]
Is there anything more powerful than gamma rays?
Is there anything more powerful than gamma rays? The measurement is exceedingly difficult since cosmic rays can outnumber gamma-rays at these energies by a factor of 10,000 to 1 or more! As the gamma-ray is making its way to our telescopes, it has to traverse through space, where there are photons and particles all around […]
Who found solar energy?
Who found solar energy? A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. How do we convert solar energy into electricity? When light energy from the sun strikes a photovoltaic solar cell, it energizes the cell […]

What are the themes of Native American literature?
What are the themes of Native American literature? Though each nation has its own stories, several themes that are common across the tribes are the link between the land and the people, a hero’s journey, and the supernatural and natural worlds. American Indian stories influenced and helped shape later American literature. What are 5 characteristics […]
What happens to electrons when they reach a light bulb?
What happens to electrons when they reach a light bulb? 2 Answers. Electrons are accelerated by the field inside the incandescent filament (the voltage drop over the light bulb is large, the field is relatively strong). The electron then interacts with the lattice, losing its energy to thermal vibrations. Then gets accelerated again, etc. Is […]
