Can someone check this pls Part 3 – Parallel & Series Circuits
For Each Circuit Shown below…
Next to each resistor write the voltage drop across that resistor as well as the current through the resistor.
Find the equivalent resistance

RTotal = 1.08

RTotal =0.82

RTotal = 1.68

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
