Given the accompanying network diagram, with times shown in days. Use Table B1 and Table B2. a. Determine the expected duration of the project. (Round intermediate calculations to 2 decimal places and final answer to 1 decimal place.) Expected Duration b. Compute the probability that the project will take at least 18 days. (Round intermediate calculations to 2 decimal places and "Probability" values to 4 decimal places.) Probability Chuck’s Custom Boats (CCB) builds luxury yachts to...

The energy level diagram of the hydrogen atom is shown the figure below

The energy level diagram of the hydrogen atom is shown the figure below. An atom generally has an electron in a given energy level, however, a transition may occur if the atom absorbs or emits a photon, or particle of light.Note: The energy of a photon can be written as \(E_{v}=h c / \lambda\) and the constants \(h c=1240 \mathrm{eV}-\mathrm{nm}\).1. In the Bohr model of the atom, energy is radiated whenA. an electron falls from an outer energy level to...

The structures of carbon dioxide and silicon dioxide are shown in the diagram below.

The structures of carbon dioxide and silicon dioxide are shown in the diagram below. Use your knowledge of structure and bonding to explain the following: a. Carbon dioxide is a gas at room temperature. b. Silicon(IV) oxide is a solid with a high melting point. c. Neither carbon dioxide nor silicon(IV) oxide conducts electricity.

The process flow diagram for an office chair is shown below. There are three steps on a worker-paced line, and no inventory is stored between the steps. The processing times are: Base: 6 minutes/unit Upholstery: 10 minutes/unit Assembly: 8 minutes/unit Demand rate is 7 units/hour. What is the resource utilization at each unit? (Assume that there is sufficient input for the process). Resource Utilization = Flow Rate/ resource capacity Raw material - Base (6min/ unit)- upholstery (10 min/unit) - assembly...

The sketch below is a free-body diagram (with all the forces shown) of a bridge. The distance are each 800 cm along the bottome of the bridge, "RL" to "A", "A" to "C", "C" to "B" and "B" to "R". The vertical height shown on the right side of the sketch is 1385 cm. The known forces are A= 5000 N, B= 3000 N and C= 10,000 N. You are to calculate the unknown reactions RLx, RLy and Rr.

Consider the molecular orbital diagram shown below, a diagram that is often applied to the first row diatomic molecules.

Consider the molecular orbital diagram shown below, a diagram that is often applied to the first row diatomic molecules. Note that this diagram comprises orbitals derived from the n = 2 valence shell of orbitals (2s and 2p). Use this diagram to determine (1) if the following diatomic molecules or ions will be diamagnetic (all electrons paired) or paramagnetic (one or more unpaired electrons), and (2) for paramagnetic species, the number of unpaired electrons.O2, N2, CO, NO, NO-, NO+, CN-,...

1. Use the information given below to solve the following: a) If Money supply (M) is fixed at 400 and Velocity (V) is fixed at 20, then draw the classical aggregate demand curve. You may show any 4 points on the curve, but keep in mind the answer to (b) below. b) If the full employment output level is fixed at 1000, draw the classical aggregate supply along with the aggregate demand above and clearly mark the equilibrium price and...
