Chapter 18, Problem 1RQ
The Apple TV™ is a personal video device created by Apple, Inc. that attaches to high- definition televisions to present streaming content to a viewer on demand, in contrast to a standard source (cable/satellite) set-top box or digital video recorder (DVR) that presents recorded or live broadcast signals on a television. According to a study conducted by the Natural Resources Defense Council in June 2011 , if consumers were to move from set-top boxes to smaller "thin" devices like the Apple TV, there would be an overall 70% reduction in annual energy costs resulting from the use of set-top boxes.
The following data table shows the typical power consumption of the Apple TV in different power states (standby/off, idle-not playing any video content, playing via Ethernet, and playing via Wifi). Create an algorithm that allows a user to provide the power currently being used by their Apple TV in units of watts and determine the state of the device. If the user provides value for the power outside the range in the following table, your algorithm should report that the state of the device is unknown.
Power Consumption of the Apple TV
| State | Power Consumption [W] |
| Off/Standby | less than 0.5 |
| Idle | 0.5 to 1.5 |
| Streaming via Ethernet | 1.5 to 1.6 |
| Streaming via Wdi | 1.6to 2 |

Refer to the Worksheet shown, set up to calculate the displacement of a spring. Hooke's law states that the force (F, in newtons) applied to a spring is equal to the stiffness of the spring (k, in newtons per meter) times the displacement {x, in meters): F= kx.
;Chapter 10, Problem 161CA, Refer to the Worksheet shown, set up to calculate the displacement of a spring. Hooke's law states
Cell A3 contains a data validation list of springs. The stiffness (cell 83) and maximum displacement (cell C3) values are found using a VLOOKUP function linked to the table shown at the right side of the worksheet. These data are then used to determine the displacement of the spring at various mass values. A warning is issued if the displacement determined is greater than the maximum displacement for the spring. Use this information to determine the answers to the following questions.
Write the expression, in Excel notation, that you would type into cell 86 to determine the displacement of the spring.…
To measure the density of a stone, a digital scale and a beaker cup filled with water are used. The balance is used to measure the mass of the stone, while the beaker is used to measure the volume of the stone. It is known that the digital balance has a resolution of 0.1 g and that the beaker cup has a resolution of 5 ml. Repeated mass measurements return the following values: 250.0 g; 249.9 g; 250.3 g; 249.6g; 250.1 g; 249.7g; 250.4 g; 250.0 g; 248.8 g; 250.2 g The volume is measured only once. Placing the stone in the beaker, a volume of displaced water equal to 50 ml is measured. Using a k=2.5, check if the density of the stone is compatible or out of line with the value ρ = (4910 ± 65) kg.m-3
(a) none of the above
(b) the values are compatible
(c) missing data to perform the compatibility test
(d) the values are discrepant

Thus, only one set of material parameters are mentioned (density, ρ; dynamic viscosity, μ).

Anthony does not take appointments, so the arrival pattern of customers is essentially random. Traditionally, the arrival rate had been about one customer every50 minutes. Two months ago, the local paper ran an article about Anthony that improved business substantially. Currently, the arrival rate is closer to one customer every 35 minutes. Haircutsrequire an average of 25 minutes, but the times vary considerably depending on customerneeds. A trim might require as little as 5 minutes, but a shampoo and styling could take as longas an hour or more. For this reason, the exponential distribution seems to provide a reasonablygood fit of the service time distribution.Anthony’s customers have always been patient, but ever since business picked up, somehave complained that the wait is too long.

Here x refers to an angular displacement measured from the vertical and t refers to time. The particle's mass is given by m=3kg. The length of the string is given by L=5 meters. Whenever the particle arrives at a location of x=(pi/12) radians from the vertical, the particle has no instantaneous speed. On both sides of the vertical, that is, x=(pi/12) radians is repeatedly observed to be a 'turning point' for the particle's periodic motion. 1.
