1. IN YOUR OWN WORDS, what do you think is the biggest role of telescopes in Modern Astronomy?
The orbital period of Planet A is 16 years and its average distance to Star B is 5.25 a.u. Another planet called Planet C has an average distance of 10.3 a.u. from Star B, using Kepler’s Third Law of Planetary Motion, compute the orbital period of Planet C to Star B in days.
30.0 g H2O at an unknown temperature is mixed with 27.0 g of water at 15.8oC in a coffee-cup calorimeter. If the final temperature of the mixture is 29.1oC, what is the initial temperature of the water?
Write a program to declare a structure and inside it is a non-static
method that returns the area of a rectangle.
Test Data and Sample Output:
Input the dimensions of a rectangle:
Length: 60
Width: 30
Expected Output:
Length: 60
Width: 30
Area: 1800
Write a program that declares a simple structure, declare at least two
variables with different data types and a static method in c#
The larger the standard deviation of a distribution, the more heterogeneous the scores in that distribution. Is this statement true?explain.
A population consists of the numbers 2, 4, 5, 9, 10. List all possible sample size of 3 from this population without replacement and determine the mean of each sample.
Create a 500 element array and load the array with a series of numbers starting at the first position that is the square of the index. For example, at position 0 would be 0, at position 1 would be 1, at position 2 would be 4, at position 3 would be 9…. Etc. Ask the user for a number between 0 and 250,000 and let them know if that number is a square. Employ a binary search.
Write a C++ program to create a class "Wall" with private data members "length & height and public member functions "findArea & Wall
What is the ∆S of N2(g) + 3H2(g) ---> 2NH3(g)?
Given
N2(g)
(J/mol x K) = 191.5
H2(g)
(J/mol x K) = 130.6
NH3(g)
(J/mol x K) = 192.3
