11.7 mph to m/s thermal neutrons are neutrons that move at speeds comparable to those of air molecules at room temperature. these neutrons are most effective in initiating a nuclear chain reaction among 235u isotopes. calculate the wavelength (in nm) associated with a beam of neutrons moving at 6.90 × 102 m/s (mass of a neutron = 1.675 × 10−27 kg). enter your answer in scientific notation.

The energy released by a nuclear fusion reaction is produced when

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.

Acapacitor is storing energy of 3 joules with a voltage of 50 volts across its terminals. a second identical capacitor of the same value is storing energy of 1 joule. what is the voltage across the terminals of the second capacitor?
