Recording Multiple Temporary Differences, Multiple Tax Rates On December 31, Colgate Inc. had an installment sale receivable balance of $180,000 recognized on its financial statements, while the amount was not recognized for tax purposes. Colgate Inc. also had a warranty accrual of $40,000 on December 31 that is not deductible for tax purposes. The installment receivable will be settled equally over the next three years. The warranty will be settled equally over the next two years. Taxable income for the current year was $1,000,000. Enacted tax rates are 25% for the current and next year, and 30% for years thereafter. Required a.

Rosie is an engineer working in the laundry factory of Fragrance Airlines to wash and clean fabrics. She is in charge of the hot water supply for the washing machine 24 hours a day. The hot water supply system is shown in Figure Q2 below with a rectangular tank of cross-sectional area 2 m x 1 m. At steady state, the inlet water supply has a temperature of 25°C and an outlet temperature of 90°C at a water level of 2 m to meet the demand of 5 liters of hot water for every kilogram of fabric being washed. The hot water temperature variation should be kept in the range of 87 - 93°C to ensure efficient washing without harming the fabrics. In normal operation, the factory is able to wash 300 kg of fabrics per hour, but the cleaning capacity can be increased when the flight frequency is at its peak. This morning, Rosie received instructions from the manager that the factory needs to increase the cleaning capacity to 500 kg per hour at 2.00 pm. However, coincidentally, there is routine maintenance for the heater which will cause the shutdown of the heater for 45 minutes starting at 2.15 pm. Rosie would like to keep the hot water supply ongoing while the heater is shut down. (Heat capacity, Cwater = 4200 J/kg·°C; Density of water, ρ = 1000 kg/m³) Inlet water supply, Wi = 25°C Hot water, W = 90°C Heat supply, Q Figure Q2 (a) Derive the model and transfer function for the temperature dynamics of the heating tank system temperature.

a) Given the common source JFET amplifier of Figure 4. Assume $V_{DD} = 20V$, $R_1 = 2M\Omega$, $R_2 = 250k\Omega$, $R_D = 2.5k\Omega$, $R_S = 1.5k\Omega$, $I_{DSS} = 8mA$, and $V_P = -4$. Determine, $V_{GSQ}$, $I_{DQ}$, $V_{DS}$, $V_G$, and $V_D$. b) Referring the JFET voltage-divider bias configuration of Figure 4 and use the same value as part (a). Prove with necessary calculation that this circuit can be used as amplifier.

Harrod's model for economic growth is given by $S_t = sY_{t-1}$, $0 < s < 1$ (1) $I_t = k(Y_t - Y_{t-1})$, $0 < k$ (2) $S_t = I_t$, (3) where S is savings, Y is the output and I is investment. Find the corresponding difference equation and answer the following questions: 1. What is the condition that ensures that the dynamic macroeconomic equilibrium is obtained in this model? Show this analytically as well as through numerical simulations.
