A string is tied down at both ends. Some of the standing waves on this string have the following frequencies: 100Hz, 200Hz, 250Hz, and 300Hz. It is also known that there are no standing waves with frequencies between 250Hz and 300Hz.

What is the fundamental frequency of this string?

What is the frequency of the third harmonic?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
