If one is trying to tile a square room which has a length of L with...
Problem 6: A photon exists in the lowest-frequency mode in a one-dimensional box of length L. There are no other photons present. The length of the box is now gradually reduced to L/4. How much work is required to do this? Give your answer in terms of L, h, and c.]
A painting company has determined that for every 110 square feet of wall space, one gallon of paint and eight hours of labor will be required. The company charges $25.00 per hour for labor. Write a modular program that allows the user to enter the number of rooms that are to be painted (different colors) and the price of the paint per gallon. It should also ask for the square feet of wall space in each room. Rooms and gallons...
The length of time (T) in seconds it takes the pendulum of a clock to swing through one complete cycle is givenby the formula T=2pi square root of L divided by 32 where L is the length in feet, of the pendulum, and pi is approximately 22 divided by 7. How long must the pendulum be if one complete cycle takes 2 seconds?
please explain in C++ only
This program determines how much it cost to paint a room Please write a program which determines and prints out three results. 1. The number of exact gallons of paint to paint the walls and the ceiling (NOT THE FLOOR) of the room if 1 gallon is enough to paint 400 square feet. 2. How many gallons of paint you need to buy since you cannot buy part of a gallon. So if you need...
Chapter 19, Problem 16 GO The drawing shows a square, each side of which has a length of L = 0.250 m. Two different positive charges 41 and 42 are fixed at the corners of the square. Find the electric potential energy of a third charge 43 = -5.00 x 10-°C placed at corner A and then at corner B. B 91 = +1.50 x 10-C 92 = +4.00 x 10°C EPEA = EPEB Chapter 19, Problem 18 A charge...
Poehling Medical Center has a single operating room that is used
by local physicians to perform surgical procedures. The cost of
using the operating room is accumulated by each patient procedure
and includes the direct materials costs (drugs and medical
devices), physician surgical time, and operating room overhead. On
January 1 of the current year, the annual operating room overhead
is estimated to be:
Disposable supplies
$299,600
Depreciation expense
75,000
Utilities
32,000
Nurse salaries
278,500
Technician wages
126,900

A parallel plate capacitor has square plates with sides of length 11 cm. The distance between the plates is 2 mm. The plates are charged up to 20volts. Part A What is the electric field between the plates? Express your answer using three significant figures. Electric field = N/C Part B What is the amount of charge on each plate? charge = C Part C What is the capacitance? Capacitance = μF Part D What is the energy stored by...
A pendulum consists of a string of length L and a mass m hung at one end and the mass oscillates along a circular arc. Part a) Familiarize yourself with the derivation of omega = Squareroot g/L to hold. i) Explain succinctly how the angular frequency of oscillation omega = Squareroot g/L comes about from Newton's Law, where g is the gravitational acceleration. ii) One assumption required is the small angle approximation: sin theta = theta and cos theta =...
(13) A brewery fermentation tank 12 m in diameter is situated in a room, which has a temperature of 15°C. The tank is constructed of 10-mm welded steel plate with 12-mm glass lining. The temperature at the inner surface of the glass lining is 50°C. Assume that the convective resistance offered by the air film on the outside of the tank equals the combined resistance of the glass and steel. The thermal conductivity of glass is 0.80 W/mK and that...
