The device can add inertia to the suspension travel without adding very much actual mass. If the suspension is thought of in an...

I thought the graticule was placed in the eyepiece so is not subject to the full magnification?

Yes, I agree with #4. An ordinary rope often has three strands, which are the bunches of fibres, and which are twisted around each...

If you pulse one carrier at both 5Hz and 8Hz you are, by doing this, causing a mixing process between the two pulse trains. In effect...

Yes. In the UK we are taught Fleming's Left Hand Rule for motor effect and Fleming's Right Hand Rule for Generator Effect. These rules...

I think the question was essentially why are even harmonics present with a stopped pipe.

These are my ideas on this question. A very interesting topic. The pipe is excited by a series of brief, unidirectional pulses which...

The energy stored might be sufficient to cause a risk to the heart. It is allowable to touch a Van de Graaff generator but not to add a...

In UK schools we are not allowed to use Leyden Jars with static machines. Your experiment amounts to the same thing. Capacitor...

For a resonant cavity, the magnetic and electric fields are each in the form of a standing wave. This is a wave that stands still. If...

The only pressure required is the head of water from the water level in the top tank to the ground. Not very much. However, if a leak...

I have tried to read all the replies, but no one seems to have suggested Osmosis. When the clay is placed in bag of water, salts from...

Regarding the spacing of resonance as you vary the wavelength (or frequency). Imagine a low frequency analogy. Take transmission line 5m...

If you change wavelength, the resonances actually occur at fixed intervals of frequency, so are not exactly uniform wavelength intervals.

Isolated systems are used for safety on construction sites etc. A transformer is used where the secondary is not connected to earth. A...
