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.
Electrons and holes in semi-counductor Metals have free electrons available in conduction band for conduction of electric current. As the valence band overlaps the conduction b
KINEMATICS II 1. The concept of the derivative of the function is exceptionally important. The derivative shows that how fast the function changes when its argument is changed.
How do I find the momentum, velocities and energy of both vehicles as they leave the impact point, the energy transferred during the collision and the momentum and energy of the ve
a. Consider an x-ray machine with a step-up transformer consisting of a primary coil of 100 turns and a secondary one with 50000 turns. If the voltage applied across the primary co
Your friend has gifted an earphone set to you. While music is on you will try to oppose the two ear phone pieces to attract. Task-I: Will they attract? If yes, why so?
Micrometer Simulation A Micrometer is used to measure the external dimensions of objects that are 3 cm or smaller, this provides precise measurements to inside 0.01 mm. The
Any motion which changes it after regular interval of time is known as periodic or harmonic motion. When the body of a pendulum moves to and fro through a short angle, the bob is k
It is the property of changing readily from a solid or liquid to a vapour. It is the speed that a chemical compounds evaporates. Higher volatility indicates faster evaporation.
Explain Force Diagrams and Addition of Forces If you have a piano and your friend offers to help move it, would it be more helpful for him to push with 100 Newtons on the
In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use
