Evolutionary Theory Questions

Please answer the question and explain fully.

Answer each of the following conceptual questions in one or a few complete sentences. It's sufficient to explain the 'main idea' and not all of the small details. (a) Why do circuit elements in series have the same current? (b) Why do circuit elements in parallel have the same voltage/potential difference? (c) forces, and sometimes from electric forces. How can you decide which one exerts the force in a given situation? The induced emf E calculated from the flux rule sometimes comes from magnetic (d) currents are anywhere nearby to create the fields. Briefly explain how electromagnetic waves can exist even when no net charges or

Explain, with the aid of a circuit diagram, how ad.c. voltmeter may be calibrated by means of a potentiometer method.A moving-coil instrument, used as a voltmeter, hasa coil of 150 turns with a width of 3 cm and an activelength of 3 cm. The gap flux density is 0.15 T. If thefull-scale reading is 150 V and the total resistance ofthe instrument is 100 000 Ω, find the torque exertedby the control springs at full scale.

Defibrillator machines are used to deliver an electric shock to the human heart, to resuscitate a heart that has stopped beating. It is estimated that a current as low as 18 mA through the heart is required to resuscitate. Using 95 kN as the resistance, determine the output voltage a defibrillator needs.

Q2 Briefly explain the condition for a system to have causality property.

A new model of electric vehicle contains two essential electronic components. Ifeither one of the components fails, the vehicle will not function.Let A and B denote the lifetimes (in years) of the two components. Assume that A ∼ Exp( 1, 20 ), that B ∼ Exp( 1, 25 ), and that A and B are independent of each other.1(a) Let C denote the time when the electric vehicle becomes inoperable due to one of thecomponents failing. Find the pdf of C.Hint: start by finding the cdf of C.(b) What is E[C]?Hint: the pdf you obtain in part (a) should be of a familiar type

You are comparing an old incandescent light bulb with a newer high efficiency LED light bulb. You find that they both have the same output of 800 lumens, which corresponds to approximately 5 W of optical power. However, you find that the incandescent bulb is consuming 60 W of electrical power, and the LED bulb is consuming 12 W of electrical power. A. Why do the optical and electrical powers not agree? B. Doesn’t conservation of energy require the two quantities to be equal?
