It's so sticky that your skin will come off rather than the glue! This, my friends, is bothersome. Why's it so potent?

3 friends went for lunch. The Bill came for Rs. 30. They shared 10 each and walked away. The Reataurant owner found mistake in the bill and had charged 5 Rupees more so, he called the waitor and told him to return 5 rupees to those 3 friends. Waitor thought How they would share 5 rupees and so he kept 2 rupees in his pocket and returned 1 rupee each to friends. So, now tell me how much amount each friend spent ? 10 - 1 = 9. Right ? and the total they spent ? 9 x 3 = 27. OK. ??? and the waitor kept 2. so, 27 + 2 = 29. ???? But earlier they paid 30 ??? So, where 1 rupee gone ??? Opps !!!!

A cyliderical metal shell with the inner radii of 0.200m and 0.300m, respectively, carries a net charge of 4.0 x 10 pow -8 C/m.Along its center there is a wire with a uniform charge of -12.0 x 10 pow -8 C/m. ( This System is smilar to an electrostatic air cleaner). (a) Find the Electric Potential caused by this system of electric charges, using the outer surface of shell as reference point for the potential. (b) An electron is formed by ionizing a gas molecule 0.00100 m from the wire. with what kinetic energy in (electron Volts) and with what speed will the electron hit the metal shell, assuming it does not suffer any collisions enroute.

Locating Whales

Hyperbolas can be used to locate objects underwater. To locate a whale in the ocean, two microphones are placed 8000 feet apart. One microphone picks up a whale noise 0.4 seconds after the second microphone picks up the same noise. The speed of sound in water is about 5000 feet per second.

a. How much farther from the whale is the first microphone?

b. Find an equation for the possible locations of the whale.

c. What is the closest distance that the whale could be to the second microphone?

d. Will the whale always be closer to the microphone that receives the signal first? Can the whale be on either branch of the hyperbola? Explain your reasoning.
