If the current is 10.0 amperes, how long will it take to deposit 105 grams of cr(s) onto the bumper? ]

Note: that M/z is the same as the equivalent weight of the substance altered 

We know, equivalent mass for a metal=atomic mass/valency. 
equivalent mass of chromium=52/6=8.67. 

so, using given values from questions in (i) we get:

or, 105 = (10*T/96500 ) * 8.67 

so, T = 105*96500/(10*8.67) = 116868.512 seconds

c. convergent boundary.

explanation:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
