1Choosing the Better Ammeter–Voltmeter Circuit
During a physics practical examination, a candidate must determine the resistance of a coil expected to be about 25 Ω at room temperature. The available elements are a 6 V battery, a rheostat, an ammeter of resistance 0.40 Ω, a voltmeter of resistance 4.0 kΩ, and the coil.

A student studies the equilibrium Fe3+(aq) + SCN−(aq) ⇌ FeSCN2+(aq) by mixing equal volumes of 0.0200 M Fe(NO3)3 and 0.0200 M KSCN, so the initial concentrations after mixing are 0.0100 M in each reactant. At equilibrium, a spectrophotometer calibrated for the deep-red FeSCN2+ ion reads [FeSCN2+] = 2.0 × 10−4 M.

A college tech fest must schedule five workshops-P, Q, R, S, and T-in five consecutive slots numbered 1 to 5, one workshop per slot. The constraints are: P must be before Q; R cannot be in slot 1 or slot 5; S must be immediately after T; and Q cannot be in slot 3.
