An amusement park ride consist of a large verticle cylinder that spins about its axis first fast enough that any person inside is held up againest the wall when the is mu_(s) and the radius of the cylider is R a. Shown that maximum period of revolation neccessary to keep the person from falling is T = (4 pi^(2) mu_(s) //g)^(1//2) b. Obtain a numerical value for taking R = 4.00m and mu_(s) = 0.400 . How many revolations per minute does the cylinder make? c.If the rate of revolation of the cylinder is make to be some what larger what happens to the magnitude of each one of the forces acting on the person ? What happens to the motion of the person ? d.If instead the cylinder rate revolation is made to be somewhat smaller what happens to the magnitude happens to the motion of the person ?

Two skaters each of mass 50 kg , approach each other along parallel paths separated by 3m . They have equal ad opposite velocities of 10 m//s . The first skater carries a long light pole, 3 m long, and the second skater grabs the end of it as he passes (assume frictionless ice). a. Described quantitatively the motion of the skaters after they are connected by the pole. b. By pulling on the skaters reduce their distance to 1m . What is their motion then? c. Compare the KEs of the system in parts a. and b. where does the change come from?

An a.c. generator consists of a coil of 50 turns and area 2.5 m^(2) rotating att an angular speed of 60 rad s^(-1) in a uniform magnetic field B = 0.3 T between two fixed pole pieces. The resistance of the circuit including that of coil is 500 Omega . Find (i) the max. current drawn from the generator. (ii) What will be the orientaiton of the coil w.r.t. the magnetic field to have (a) maximum (b) zero magnetic flux ? (iii) Would the generator work if the coil were stationary and instead, the pole pieces rotated together with the same speed as above ?

CO_2 and H_2 O absorbs strongly in the infrared rrgion and its presence in the atmospheere dectrases the loss fo heat form the enrth by radistiion . This global warming is called the greenhouse effect (other gases , including the oxides of nitraongen form car exhauset freons from aerosols and refrigeratirs and methane from bacteria in the soil and in the rument cows , also add to the reeenhouse effect ). The concentration fo atmospheric CO_2 has increased by 10% . The is rsulting in the increase in the mean temperature fo the earth by 2. 5^@ C , varying form 2^@ C t the equlator to 4^@ C at the poles . This could have dramatic effects on the climate. As a result of freenhouse effect , thers can be : A: an increase in rate of egvaporation of water thus, untimely more rain , floodingn tec . B: tropical storms in certain parts of the workd C: a decrease in pH of the soil D: an increase in pH of the soil select correct altemate :
