A string is 41 cm long and has a mass of 2 g. A wave travels at 8 m/s along this string. A second string has the same length but half the mass of the first. If the two strings are under the same tension, what is the speed of a wave along the second string? Answer in units of m/s.

What statement describes the process of solar nuclear fusion? hydrogen atoms are fused into deuterium, then helium-3, then helium-4, each step giving off large amounts of energy. hydrogen molecules are fused together and become oxygen molecules, giving off large amounts of energy. helium molecules are fused together and become hydrogen molecules, giving off large amounts of energy. hydrogen atoms are fused into deuterium, then helium-4, then back into hydrogen, each step giving off large amounts of energy.
