I think these so called vaastu experts are spreading superstition & fooling people. They try to create doubts in the mind of people about their surroundings.

Please clear my doubts.

There was a theory (regarded as fact, I think) however many hundred years ago that bodily fluids could only be created by the body, but it was disproved when a scientist (I think German) created Uric Acid in a lab setting... what was it? Wiki page, anyone? I don't know what to search for

QUESTION ONE:

Is there any way the two individual frequencies can be combined to give the same beat frequency previously measured?

QUESTION TWO:

There are commercial products available called active noise cancellers, which consist of a set of headphones, microphones, and some electronics. Intended for wearing in noisy environments where the user must still be able to hear (for example, radio communications), the headphones reduce noise far beyond the simple acoustic isolation of the headphones. How does such a product work?

You don't have to answer both, but whatever you can help with is greatly appreciated (I will choose best answer).

Thanks everyone!

A small plastic ball (similar to a ping-pong ball) with mass 2.5g is attached by a thread to the bottom of a beaker. When the beaker is filled with water so that the ball is totally submerged, the tension in the thread is 0.03N. The density of water is 1000kg/m^3 and the acceleration of gravity is 9.81m/s^2.
Determine the diameter of the ball.
