Should U.S. Police Forces, which are severely restricted in how they can interrogate and use electronic surveillance, be granted more freedom and power in order to implement counter-terrorist measures? Consider the possible ramifications of your answer.
This is a multiple choice question on plane wave propagation in electromagnetic field as found in the attached file.
“Millipore New Product Commercialization: A Tale of Two New Products" by V. Kasturi Rangan, Kevin Bartus http://hbr.org/product/millipore-new-product-commercialization-a-tale-of-two-new-products/an/594010-PDF-ENG How would you evaluate the LC/MS NPD effort? Which were the right decision and which were faulty?
1) Under what conditions is the impedance in an LRC circuit a minimum? 2) At a given instant in time, a traveling electromagnetic wave is noted to have its maximum magnetic field pointing west and its maximum electric field pointing south. In what direction is the wave traveling? If the rate of energy flow is 500W/m^2, wh
How are light and sound alike? How are they different?
A police car is moving to the right at P m/s, while a speeder is coming up from behind at a speed I m/s, both speeds being with respect to the ground. The police officer points a radar gun at the oncoming speeder. Assume that the electromagnetic wave emitted by the gun has a frequency of H Hz. Find the magnitude of the differenc
Find the magnitude of the difference between the frequency of the emitted wave and the wave that returns to the police car after reflecting from the speeder's car.
A police car is moving to the right at X m/s, while a speeder is coming up from behind at a speed X m/s, both speeds being with respect to the ground. The police officer points a radar gun at the oncoming speeder. Assume that the electromagnetic wave emitted by the gun has a frequency of f Hz. Find the magnitude of the differenc
The broadcast antenna of an Am radio station is located at the edge of town. The station owners would like to beam all of the energy into town and none into the countryside, but a single antenna radiates energy equally in all directions. The attached figure shows two parallel antennas separated by a distance L. Both antennas bro
What was the historical scope of telecommunications? How has it changed? In what ways might it change in the future? How does IS fit into these trends?
It takes light 20 min to travel from Mars to Earth. How might this affect a conversation between an astronaut on Mars and people on Earth? Explain. Suppose an ultra-powerful telescope were used for visual communication. Would this telescope speed things up? Why?
(See attached file for full problem description) --- 20.25 Part A : At 20 degree C, what is the frequency of a sound wave in air with a wavelength of 17.0 cm ? Part B : What is the frequency of an electromagnetic wave with a wavelength of 17.0 cm ? Part C : What would be the wavelength of a sound wave in water t
Please answer all questions with full explanations 1) An ultrasound wave has frequency 100 kHz and wavelength (in air) of 3.5mm. What is the speed of these ultrasonic waves? 2) 3mm wavelength radar waves have speed 3.00 x 10(8) ms(-1) (as do all electromagnetic waves in air) what is their frequency? 3) Ultrasound is a l
The average intensity of sunlight reaching the earth is 1390 W/m^2. A charge of 2.6 x 10^-8 C is placed in the path of this electromagnetic wave. (a) What is the magnitude of the maximum electric force that the charge experiences? (b) If the charge is moving at a speed of 3.7 x 10^4 m/s, what is the magnitude of the maximum m
1. If a child's temperament is not a good "fit" with the temperament of is caregiver, how can this slow down his socialization? 2. How do a person's peers socialize him? 3. What are the three broad categories of temperament people can have? 4. List several of the rather scary, ecological trends of society that challeng

The theatre is putting on a new musical and they are changing from traditional rifle microphones to radio microphone system. The theatre has some concerns over doing this, they are: transmitter operation with regard to power supplies, inter-modulation problems and choice of transmitter frequency band and output power. Please
Basic EM equation for electric field Questions and solution contains special EM symbols. please see attached in word document.
The speed of electromagnetic waves through vacuum or air is 3X10^8m/sec. Find the frequency of the green light with a wavelength of 5.4X10^-7m and the wavelength of radio waves broadcast at 900 kilohertz.
The speed of a transverse wave on a string is 450 m/s, while the wavelength is 0.18m. The amplitude of the wave is 2.0mm. How much time is required for a particle of the string to move through a total distance of 1.0 km?
Although philosophy is divided into discrete inquiries, these areas have synergistic relationships and dependencies. Ontological issues are arguably the most important, serving as the ground of inquiries and repository for historical findings.
