Studying for finals, need to know why I got these wrong Please be detailed! Do all the problems. 19 points for each problelm) in the areroton beam that carries a total current /of 3,5S A has a radius of R -0006 m. The current density s fe proton beam increases with the radial distance, from the center. This is expressed mathematcallsy density at asJJo /R), where R is the radius of the beam and Jo is a constant that describes the current the edge. i) Determine the value of Jo 3 ? n (o.co6)s so P-TV USS0.15 per kw-h? pplied to the ire (nd to end) is 48.0 V, what is the cost for 72.0 h of electricity at b) The current supplied by a battery as a function of time is I)- (0.88 A)e-(6.0 h where uis in hours. What is the total number of electrons transported from the positive electrode to the negative electrode in the time period between 1 = 0.00 hr and 14.00 hr? (e-1.60 x 10-19 C) C.

Explanation / Answer

Note that the power you calculated was right but it is important to keep in mind the unit should be same after you put the values in the formlua, here it goes like this

estimate= 0.15 * 103 * 72 * (170.4) J

Estimate = 1840320 J
