SOLVED: When a glass tube filled with hydrogen gas is heated to a high temperature, the gas will glow, emitting a red light that is characteristic of the element. When this light passes through a prism, it produces a spectrum composed of discrete lines that always appear at specific frequencies and wavelengths. Explain why does light emitted by hydrogen gas and other gaseous elements produce a "lined spectrum" instead of a rainbow-like "continuous spectrum" like sunlight?Explain what the "wave-p

SOLVED:A spherical weather balloon of 2 m diameter is filled with hydrogen. The total mass of the balloon skin and the instruments it carries is 29.682 kg. If at a certain altitude the density of air is 1.0 kg m^-3 and is ten times the density of hydrogen in the balloon, determine the steady upward velocity of the balloon. Take viscosity of air to be 1.8 ×10^-5.
