Human-powered aircraft require a pilot to pedal, as in a bicycle, and produce a
sustained power output of about 0.30 hp.

The Gossamer Albatross flew across the English Channel on June 12, 1979, in 2h 49 min.

(a) How much energy did the pilot expend during the flight?

(b) How many Snickers candy bars (280 Cal per bar) would the pilot have to consume to be “fueled up” for the flight?

[Note: The nutritional calorie, 1Cal, is equivalent to 1000 calories (1000 cal) as defined in physics. In addition, the conversion factor between calories and joules is as follows: 1Cal = 1000 cal = 1 kcal = 4186 J. ]

A particle of mass m with charge  q moving with uniform speed v normal to a uniform magnetic field describe a circular path of radius r. Derive expression for (1)time period of revolution and (11) kinetic energy of the particle.?

“if we are given an irregular shaped wire carrying current provided its cross sectional area is constant then we can find the net force on that conductor by joining the two ends of the conductor and thinking that joined part as a conductor and current should be flown in the same sequence then the force experienced by that conductor in magnetic field will give us the net force on that conductor. it is an easy method to find force on any shaped conductor……..its my own theory with some examples too”
