Task 7 a) The voltage Vin an electric circuit containing resistance, R and capacitance, Cin series with a constant voltage source E is given by the differential equation: dV 1 dt RC (E-V) Solve the equation and find V in terms of time t given that when t=0, V=0. b) A hot body is exposed to an environment at a constant temperature of 280K. If after 1 minute the temperature of the body is 350K and after 5 minutes it is 310K determine an expression for the temperature (0) and use Excel to sketch the graph of against time fort from 0 to 5 minutes and comment on the shape of your graph. Note: Where T is kelvin temperature of the environment which is constant, О is the kelvin temperature of the body, t is time in seconds and kis a constant for the body and: de = k(0-T) dt
