Acertain baryon (a subatomic particle) has a charge q > 0. the baryon moves with a kinetic energy k in a circular path of radius r in the presence of a uniform magnetic field of magnitude b. (use any variable or symbol stated above as necessary.) (a) what is the speed of the baryon? assume the speed is low compared to the speed of light. (b) what is the mass of the baryon?

The answer which is not a detail carson used to describe the pool in the cave at low tide is b.  hundreds of periwinkles browse the branches and roots of the trees. 

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
