- New Equation of Change? The tax liability T in dollars, for a company that has an initial tax liability of 6200 is dTdt=0.02T. Here, t is time in years. What would be the equation of change for the tax liability if the initial tax liability were 7000?arrow_forwardWaterWater flows into a tank, and a certain part of it drains out through a valve. The volume v in cubic feet of water in the tank at time t satisfies the equation dvdt=5(v/3). If the process continues for a long time, how much water will be in the tank?arrow_forwardpH The hydrogen ion concentration of fresh egg whites was measured as [H+]=1.3x108M Find the pH, and classify the substance as acidic or basic.arrow_forward
- Temperature An object at a temperature of 80C is placed in a room at 20C . The temperature of the object is given by T=20+60e0.06m where m represents the number of minutes after the object is placed in the room. How long does it take the object to reach a temperature of 70C ?arrow_forwardCharging a Battery The rate at which a battery change is slower the closer the battery is to its maximum change c The time (in hours ) required to change a fully discharged battery to a charge C is given by t=In(1cc) Where k is a positive constant that depends on the battery. For a certain battery, k=0.25 . If this battery is fully discharged, how long will it take to change to 90% of its maximum charge c ?arrow_forwardElectricity In a series resistance-capacitance DC circuit, the instantaneous charge Q on the capacitor as a function of time where t=0 is the moment the circuit is energized by closing a switch is given by the equation Qt=CV1-e-t/RC, where C,V, and R are constants. Further, the instantaneous charging current Ic is the rate of chage of charge on the capacitor, or Ic=dQ/dt. Source: Kevin Friedrich. a. Find the expression for Ic as a function of time. b. If C=10-5 farads, R=107 ohms, and V=10 volts, what is the vharging current after 200 seconds? Hint: When placed into the function in part a, the units can be combined into amps.arrow_forward
