Answer: speed is different from velocity and acceleration
Explanation:
Acceleration is rate of change of velocity per unit time and velocity is rate of change of displacement(shortest path between initial and final point) per unit time. but speed is Distance per unit time. The difference between speed and other two terms is that, speed is scalar i.e it has only magnitude, velocity and acceleration has both velocity as well as direction.
- a(acceleration) = dv/dt
- v(velocity) = ds/dt
- speed = distance/time
Answer:
thats a really cool design or whatever you got there.
Explanation:
niceeeeeeee :)
Answer:
The solution code is given below
- using System;
- using System.Linq;
-
- public class Program
- {
- public static void Main()
- {
- string[] letters = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T","U", "V", "W", "X", "Y", "Z"};
-
- Console.WriteLine("Please input a letter: ");
- string input_letter = Console.ReadLine();
-
- if(letters.Contains(input_letter)){
- Console.WriteLine("OK");
- }else{
- Console.WriteLine("Error. Not uppercase letter.");
- }
- }
- }
Explanation:
Firstly we import the necessary libraries, System and Linq (Line 1-2).
Next we create a string array to hold all uppercase letters (Line 8).
Next, we prompt user to input a letter using the ReadLine() method (Line 10 - 11)
At last, we define if and else conditions to check if the letters contains the input letter. If so, print ok else print an error message. (Line 13-17)
