Question: If the distance between two objects is doubled, by how much should the mass of the first object increase, assuming the mass of the second is a constant, to maintain the same gravitational attraction.
A motorcycle has a constant speed of 24.0 m/s as it passes over the top of a hill whose radius of curvature is 131 m. The mass of the motorcycle and driver is 348 kg.
A conductor is found to be transparent to ultraviolet light with wavelengths shorter than 200 nm. Assuming a permittivity equal to that of vacuum, and assuming that the effective mass equals the free-electron mass, calculate the Hall coefficient.
