I am still confused. I do not know what numbers to use from the problem into the equation.

[An object with mass 30 kg and specific gravity 3.6 is placed in a fluid whose specific gravity is 1.2. Neglecting viscosity, which of the following is true? A. The acceleration of the object is 1\3g and its apparent weight is 100N B. The acceleration of the object is 2\3g and its apparent...

If two wavelengths of standing waves on a 12 meter rope secured at both ends are 2 meters and 1 meter, which of the following could not be a standing wave wavelength on the same rope with the same tension? Choices are: 4m, 2.5m, 1.5m, 67cm 12-2 =10, so 1\2 would be 5 and 12-1 = 11, so...
