The upward speed v(t) of a rocket at time t is approximated by v(t)=at^(2)+bt+c,0letle100 where a, b and c are constants. It has been found that the speed at times t=3, t=6 and t=9 seconds are respectively, 64, 133, and 208 miles per second respectively. Find the speed at time t=15 seconds. (Use Gaussian elimination method.)

With regards to toxicity and the need for dilution in water, how different are ureotelic and uricotelic excretions? Give examples of animals that use these types of excretion. Ureotelism: 1. The process of excreting urea is called ureotelism. 2.Animals which are found in places where water availability is not abundant have this mode of excretion. 3. They convert Ammonia produced in the body into urea in the liver and release it to the blood. This is filtered and excreted by the kidneys, Eg: Mammals, many terrestrial amphibians and marine fishes. 4.In terms of toxicity urea is more toxic than uric acid but it is soluble in water and is thus excreted as urine.

A narrow beam of singly charged carbon ions, moving at a constant velocity of 6.0 X10^4 ms^(-1), is sent perpendicularly in a rectangular region having uniform magnetic field B=0.5 T . It is found that two beams emerge from the field in the backward derection, the separations from the incident beam being 3.0 cm and 3.5cm. Identify the isotopes persent in the ion beam. Take the mass of an ion = A(1.6 X10^(-27) kg, where A is the mass number.
