When switch S in the figure is open, the voltmeter V of the battery reads 3.08 V. When the switch is closed, the voltmeter reading drops to 2.98 V, and the ammeter A reads1.64 A. Assume that the two meters are ideal, so they don't affect the circuit.
a) Find the emf.
b) Find the internal resistance of the battery
c) Find the circuit resistance R.

What are the dimensions of the box so that the cost of materials is minimized?
A closed rectangular box has a volume of 16 cubic feet. It’s made of two different materials; the top and bottom are made of a material that costs 10 cents per square foot while the sides are made of material that costs 5 cents per square foot.

Recall the following definition: For X a topological space, and for A ⊆ X, we define the closure of A as cl(A) = ⋂{B ⊆ X : B is closed in X and A ⊆ B}. Let x ∈ X. Prove that x ∈ cl(A) if and only if every neighborhood of x contains a point from A. You may not use any definitions of cl(A) other than the one given.
