MC1. You are asked to design a flashlight that will last at least eight hours without having to be recharged or having to replace the batteries. You also want it to be as small and as lightweight as possible. The flashlight will make use of an array of light emitting diodes (LEDS) that consumes 600 mW when supplied with by a 3 V source. Standard 1.5 V battery sizes include (listed from smallest and lightest to the largest and heaviest) AAA (1150 mAh), AA (2850 mAh), C (3800 mAh), and D type cells (8000 mAh). What is the smallest cell size that you can select if your design consists of two identical batteries connected in series?

Background and formula: Ellipse has two types of axis - Major Axis and Minor Axis. The longest chord of the ellipse is the major axis. The perpendicular chord to the major axis is the minor axis, which bisects the major axis at the center as shown in Figure 1. Ellipse is different with circle which has only one radius. There is no simple formula to calculate the exact or accurate value of perimeter of an ellipse. Therefore, we use approximation formulas to calculate the approximate value of an ellipse's perimeter. One of the approximation methods is called Ramanujan Formula as follows: p zn[3(a+b) – Г(За + b) (а + зь)| where a is the semi major axis and b is the semi minor axis of the ellipse, respectively, as shown in Figure 1. be major axis Figure 1.

Vehicles stop automatically when a traffic light turns red but a driver doesn't apply brakes. Use two LEDs and one button. Assume that the button is a brake pedal, a red LED is a red traffic light, a yellow LED is a self-brake system. When the traffic light turns red your system monitors if a driver applies a brake within two seconds. If no brake is applied within two seconds, the yellow LED turns on, which indicates the vehicle activates a self-brake system. Design an electric circuit with necessary components required for the system and write pseudocode for the same by explaining the ideology/principle of working of the system designed.

Give Authentic and Relevant Answer. Software Engineering Question: The client's ultimate objective is to have an online software system that gives information about the movies that the client sells to customers online. The system gives information about movies and actors/actresses. That is, the system should be accessed online. Each movie is identified by title and year of release. A movie has a genre (drama, comedy, etc.), a running time, and one director. A movie is made at a movie studio and may have multiple producers (people in charge of the movie production). A movie studio has a unique name and address, and may make one or more movies. Producers are identified by name and date of birth and produce one or more movies. Directors are also identified by name and date of birth and direct one or more movies. Assume that directors don’t act or produce movies. Actors are identified by name and date of birth, and may appear in one or more movies. An actor who appears in a movie, has a…
Context: Measuring Air Quality Levels of various air borne pollutants such as Nitrogen Monoxide (NO), Nitrogen Dioxide (NO2) and particulate matter (also called particle pollution) are all major contributors to the measure of overall air quality. For instance, NO2 is measured using micrograms in each cubic metre of air (㎍/m3). A microgram (㎍) is one millionth of a gram. A concentration of 1 ㎍/m3 means that one cubic metre of air contains one microgram of pollutant. To protect our health, the UK Government sets two air quality objectives for NO2 in their Air Quality Strategy The hourly objective, which is the concentration of NO2 in the air, averaged over a period of one hour. The annual objective, which is the concentration of NO2 in the air, averaged over a period of a year. The following table shows the colour encoding and the levels for Objective 1 above, the mean hourly ratio, adopted in the UK.
