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 […]
Why does the queen hold her wrist?

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 […]
Is it safe to live by a nuclear power plant?
What happens if I never stretch?
What happens if I never stretch? Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight. Then, when you call on the muscles for activity, they are weak and unable to extend all the way. […]

Which of the following is not considered a region of the spinal cord? The d. pelvic region is not considered a region of the spinal cord. Which cells form myelin in the spinal cord? Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and […]
What are the three main types of telescopes?
What are the three main types of telescopes? Types of Telescope. There are three main types of telescope. These are refracting telescopes, Newtonian telescopes and Schmidt-Cassegrain telescopes. Why do we use different types of telescope? Most objects give off several frequencies of energy simultaneously. Your body, for instance, glows in thermal infrared down to radio. […]
What is the basic unit of all matter on earth?
What is the basic unit of all matter on earth? Atoms are the basic units of matter and the defining structure of elements. The term “atom” comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. What is the […]
