A double-pane window has a vertical height of 0.9-m and a width of 1.4-m that consists of two layers of glass separated by a 10-cm air gap at atmospheric pressure. The room temperature is 26°C while the inner glass temperature is 18°C. Radiation heat transfer is neglected. Steady operating conditions exist. **Properties** For natural convection between the inner surface of the window and the room air, the properties of air at 1 atm and the film temperature of $$(T_x + T_{∞})/2 = (18 + 26)/2 = 22°C$$ are: $$Pr = 0.7304; k = 0.02529 \, W/m.K; \nu = 1.534 \times 10^{-5} \, \text{kg/m}^3$$ **Properties** For natural convection between the two glass sheets separated by an air gap, we can set an initial guess of $$T_2 = 0°C$$. The properties of air at 1 atm and the anticipated average temperature of $$(T_1 + T_2)/2 = (18 + 0)/2 = 9°C$$ are: $$Pr = 0.7339; k = 0.02431 \, W/m.K; \nu = 1.417 \times 10^{-5} \, \text{kg/m}^3$$ (a) [20 marks] Calculate: (a) the temperature ($$T_2$$) of the outer glass layer; and (b) rate of heat loss ($$Q$$) through the window by natural convection.

Which of the following build (s) new strands of DNA? The origins of replication The leading strand Parental DNA DNA polymerases The lagging strand Request Answer Part B Which statement about DNA replication is CORRECT? The lagging strand is built continuously. The leading strand is built continuously, and the lagging strand is built in pieces. The lagging strand is one of the strands of parental DNA. DNA ligase helps assemble the leading strand. The leading strand is one of the strands of parental DNA. Request Answer Part C During DNA replication, which nucleotide will bind to an A nucleotide in the parental DNA? T U G C A Request Answer Part D The molecule that seals the gaps between the pieces of DNA in the lagging strand is DNA ligase. the replication fork. DNA polymerase. the leading strand. RNA. Request Answer Part E Which statement about DNA replication is FALSE? The lagging strand is made of a series of pieces that must be joined together to make a continuous strand. DNA ligase adds nucleotides to the lagging strand. DNA polymerase builds a new strand by adding DNA nucleotides one at a time. Because the two strands of parental DNA run in opposite directions, the new strands must be made in different ways. The two strands of parental DNA are separated during DNA replication.

# MECE 3338: Funwork 10 – Due Date Monday 11/13/2023 11:59 PM ## Problem 1: Consider the following system that consists of an inverted pendulum OB with mass **m = 6 kg** and length **2α** where **α = 0.5 m**. The pendulum rotates about its bottom end point O with rotational viscous friction coefficient **b_r = 8 N m s/rad** and is supported by two horizontal springs of equal stiffness **k = 100 N/m** attached at its middle point C, as shown. A horizontal spring of same stiffness **k = 100 N/m** is attached at the pendulum's top point **D**. A **displacement input z(t)** at the free end point A of the spring sets the system to motion. Small angular displacements from the vertical equilibrium position of the pendulum are considered. a) Derive the transfer function **G(s)** of the system from the **displacement input z(t)** to the **angular displacement output θ(t)** of the pendulum. Use the values of the system parameters **α, m, k** and **b_r** as stated above in the calculation of **G(s)**. b) Considering a **sinusoid displacement input z(t) = A sin(αt)** find the **worst-case excitation frequency α'** that results in the **maximum steady-state angular displacement amplitude |θ|_max** of the pendulum from its vertical equilibrium position. c) Find this **maximum angular displacement amplitude |θ|_max** if the amplitude of the sinusoid displacement input excitation is **A = 0.1 m**. d) Sketch the **magnitude Body diagram** of the transfer function **G(s)** from the displacement input **z(t)** to the angular displacement output **θ(t)** of the pendulum. e) We want to reduce the steady-state angular displacement amplitude **|θ|_max** to half of the value calculated in c), that is, **|θ'| = |θ|_max / 2**, by changing the rotational viscous friction coefficient to a new value **b_r**. What should be this **new value of the rotational viscous friction coefficient b_r'** such that at the excitation frequency **α'** calculated in b) **the steady-state angular displacement amplitude is reduced by half?** Fig (1): Vertical pendulum with pulling spring on top
