Expert Solution
Note :-- pay attention to the sign of electric field, emf
induces and absolute permittivity of free space they look
alike.
So carefully solve the question according to the solution
provided.
1. A rechargeable battery with emf 1.52 V and internal
resistance 0.75 Ω is connected positive to positive and negative to
negative with a 3.00 V battery with internal resistance 1.4 Ω.
Assume the emf of each battery remains constant.
(a) Find the current.
(b) How much energy will be stored in the rechargeable battery
in 1.00 minute?
(c) Determine the efficiency of this charging arrangement.
(d) How could the efficiency be improved (and wasted energy be
reduced)?
The standard emf for the cell using the overall cell reaction
below is +2.20 V:
2Al(s) + 3I2(s) →→ 2AI3+(aq) +
6I-(aq)

Theoretical Centripetal Force= (mv^2)/r (This is in the
manual)
Experimental Centripetal Force= |Max-Min|/2 (since the Min is
negative, the two minus signs would become a plus)
1. Calculate the theoretical value for the centripetal force for
the brass mass using the formula ?(v^2/r). (5 points)
2. Find the experimental value of the centripetal force for the
brass mass. The amplitude of...
