Part A What potential difference is needed to give a helium nucleus (Q=2e) 50.0 keV of kinetic energy? A point charge Q creates an electric potential of +125 V at a distance of 20 cm Part B A point charge Q creates an electric potential of +125 V at a distance of 20 cm . What is Q? Express your answer using two significant figures.
What potential difference is needed to give a helium nucleus (Q=3.2×10^−19 C) 120 keV of kinetic energy?
what is the magnitude of the potential difference needed to give an alpha particle (composed of 2 protons and 2 neutrons) 239.0 keV of kinetic energy? Answer] incompatible units. No conversion found between-ker" and the required units. Tries 1/99 Press ustes Post Discussion
Trolls move by transferring electric potential energy into kinetic energy. What potential difference is needed to accelerate a troll (mass of 20kg)from rest to a speed of 30 m/s if the troll has a charge of 5mC? Neglect friction.
If the alpha particles have an initial kinetic energy of 7.7 MeV, then assuming a head-collision between an alpha particle (helium nucleus with +2e charge) and a gold nucleus (79 protons, so +79e charge), and using conservation of energy at the point of closest approach when all of the alpha particle's kinetic energy is converted to electric potential energy, calculate the approximate distance of closest approach (and thus coarsely estimate the size of the nucleus)
An electron in a television picture tube has a classical kinetic energy of 78 keV, which is the kinetic energy that Newton would calculate using the measured speed and rest mass of the electron. What is the actual kinetic energy of the electron; that is, what is the value found using the relativistic result for the kinetic energy? (Give your answer in units of keV)
A) What is the speed of an electron with kinetic energy 780 eV ? B) What is the speed of an electron with kinetic energy 0.40 keV ?
Alpha decay is nuclear decay in which a helium nucleus is emitted. If the helium nucleus has a mass of 6.646 ✕ 10-27 kg and is given 7.00 MeV of kinetic energy, what is its velocity? Answer: _________ c
What is the simple difference between Work, kinetic energy, potential energy, and energy? Could examples be provided? Thanks!
4. A charge Q = + 50 nC is fixed in place at the origin. A Helium nucleus with charge q+2e is released from rest at point A on the x- axis, 1.00mm from Q. Later it gets to point B on the x-axis, 25.0 mm from Q. Q-+50.00nC 1.00mm 25mm ?4-1.00mm-01 a) What electric potential (in volts) does Q produce at point A? b) Moving from A to B, what change in P.E. is experienced by the Helium Atom?...
