A neutron in a nuclear reactor makes an elastic head-on collision with a carbon atom initially at rest. (The mass of the carbon atom is 12 times that of the neutron.) What fraction of the neutron’s original kinetic energy is retained by the neutron?
When a 32.0-V emf device is placed across two resistors in series, a current of 11.0 A is flowing in each of the resistors. When the same emf device is placed across the same two resistors in parallel, the current through the emf device is 56.0 A. Wh..
A modern-day zeppelin holds 9,030 m3 of helium. Compute its maximum payload at sea level. (Assume the helium and air to be at 0°C and 1 atm. The answer I get is 9391.2 kg but seems to be wrong answer and I have run out of ideas.
