Create a program that will overload a function sum, which takes two
parameters of numeric data type and prints their sum function for
integers and floats.
Write a program which will do the following:
Create a class called
Triangle
. The three sides of the triangle
are private
members of the class. The
class should contain a member f
unction to determine whether a
triangle is equilateral, isosceles or
scalene.
The class
should
also
include member functions which will give area and perimeter of the
triangle. The side
s of the triangle should be taken as input from the user in the main function.
Compute the contracted length of an
object whose initial length 30 m and travel with a velocity 0.65c?
There is a set of twins, one an
astronaut, the other works for mission control of NASA. The astronaut leaves on
a deep space trip traveling at 95% the speed of light. Upon returning the
astronauts clock has measured ten years, so the astronaut has aged 10
years. What is the time that the
earth-bound brother measures while his twin was on his exploration in space?
How old is he?
Assume that lightning strikes completely vertically and that a known current flows from the cloud into the ground for some time. We want to detect a lightning strike with the help of a coil that is connected directly to a voltmeter. Explain which phenomenon is responsible for lightning detection. Sketch the magnetic field of lightning and how the coil should be oriented for the effect to be strongest.
A polarizer and analyzer are oriented so that the amount of transmitted light is maximum.
Through what angle should either be turned so that the intensity of transmitted light is
reduced to (a) 0.75 and (b) 0.25 times the maximum intensity?
Suppose it costs XYZ Airline 120,000 dollars to fly its 500 - seater A380 passenger plane from Dubai to London. The flight service does not include drinks/meal. The passengers pay for food and drinks separately on demand.
(a): What is the average cost of a Dubai – London seat on this plane?
(b): Currently XYZ airline charges 550 dollars for a Dubai-London ticket (economy) on this plane. Suppose 10 economy seats are left unsold when the plane is starting to board the passengers. A standby passenger offers to pay 250 dollars for a seat. Should the airline sell the ticket to this passenger at 250$? Yes or No? Briefly explain your reason.
N₂+ 3H₂ → 2NH₃ If 14.00 g of N₂ reacts with the correct amount of H₂ and produces 17.03 g of NH₃ then what mass of H₂ is required for a complete reaction, with no waste reactant?
