The formula above expresses the square of the speed v of a wave moving along a string in terms of tension T, mass m, and length L of the string. What is T in terms of m, v, and L ?
Explanation
Choice A is correct. To write the formula as T in terms of m, v, and L means to isolate T on one side of the equation. First, multiply both sides of the equation by m, which gives , which simplifies to mv2 = LT. Next, divide both sides of the equation by L, which gives
, which simplifies to
.
Choices B, C, and D are incorrect and may be the result of incorrectly applying operations to each side of the equation.
