1. Fill a sink or bath tub with water.
2. Practice tapping the cork on the surface of the water (about 3 _times per second works well) to create evenly spaced waves.
3. Tapping the water at the same frequency, move your object in a straight line in one direction in a broad, sweeping motion-not too fast, or you will have a hard _me seeing the effects!
4. As you move the object, try to observe the spacing of the waves extending in front of the object compared to the ones behind it.
5. Try a number of different speeds and tapping frequencies until you can see a spacing difference between the front and back waves.
It makes sense that copper should be used because it could heat up faster, making the event more efficient.
Triangle of force Two or more forces can be added or subtracted to produce a Resultant Force . If two forces are equal but act in opposite directions, then obviously they can
It is worth noting that positive charges have lines of forces moving out from them and negative charges have lines of forces entering them.for attraction of charges one charge must
a) How much charge should be placed on it to raise its potential to 10,000 V. b) A parallel plate capacitor having plate area 100 cm 2 and separation 1.0 mm holds a charge of

Can lighting optic fiber to be spliced or joined? All fibers can be spliced along with difficulty and more or less success. The problem is the losses resulting from that a join
what is wedge constraint? explain with example.
What are the advantages of fibers optics? Glass fiber optics are extremely resilient and ideally fine for working in places where the actual conductor will tend to extreme temp
