Information is stored on a compact disk in a coded pattern of tiny pits arranged in a track that spirals outward toward the rim

of the disk. As the disc spins inside a player, the track is scanned at constant linear speed by a stationary scanning head. How must the rotation speed of the disc change as the player's scanning head moves radially outward in order to scan the track at constant linear speed

Answer:

(i) The rotation speed must stay the same.

(ii) The rotation speed must increase.

(iii) The rotation speed must decrease.

Explanation:

According to Equation

10.10, the angular speed must therefore vary as the laser–lens system moves

radially along the disc. In a typical CD player, the constant speed of the surface at

the point of the laser–lens system is 1.3 m/s.

A triangular number is a number that is the sum of the integers from 1 to some integer n. Thus 1 is a triangular number because
neonofarm [45]

Answer:

  1. m = 3
  2. n = 20
  3. triList = []
  4. current = 0
  5. for i in range(1, n + 1):
  6.    current = current + i  
  7.    if(current >= m and current <= n):
  8.        triList.append(current)
  9. print(triList)

Explanation:

The solution code is written in Python 3.

Firstly, create variable m and n and set the value 3 and 20 to the variables (Line 1 -2)

Create a triangle number list (Line 4)  and another variable current to hold the value of current total of triangle number (Line 5).

Create a for loop and iterate through the number between m and n (Line 6).  Calculate the current total of triangle number (Line 7) and proceed to check if the current triangle number is bigger or equal to m and smaller and equal to n, add the current triangle number to triList (Line 8-9).

Print the triList (Line 11) and we shall get [3, 6, 10, 15]

Ajay wants to read a brief overview about early settlers in the United States. Which type of online text source should he most l
Tanzania [10]
Well, integrity is a must if you are reading anything. So it would be any website that has either a .edu or a .gov at the end of a URL. 

I never suggest Wikipedia for brief, since 100's of people will edit one topic at a time, the answer to what he is looking for is buried in 18 pages about one settler in the United States!

kaheart [24]

Answer:

Explanation:

The following code is written in Java and creates the BankAccount class with all of the requested methods, including the constructor, getter and setter methods, withdraw methods, and even the transferToSavings method. A preview can be seen in the attached image below.

class BankAccount {

   private String customerName;

   private double savingsBalance, checkingsBalance;

   public BankAccount(String newName, double amt1, double amt2) {

       this.customerName = newName;

       this.checkingsBalance = amt1;

       this.savingsBalance = amt2;

   }

   public String getCustomerName() {

       return customerName;

   }

   public void setCustomerName(String customerName) {

       this.customerName = customerName;

   }

   public double getSavingsBalance() {

       return savingsBalance;

   }

   public void setSavingsBalance(double savingsBalance) {

       this.savingsBalance = savingsBalance;

   }

   public double getCheckingsBalance() {

       return checkingsBalance;

   }

   public void setCheckingsBalance(double checkingsBalance) {

       this.checkingsBalance = checkingsBalance;

   }

   public void depositChecking(double amt) {

       if (amt > 0) {

           this.checkingsBalance += amt;

       }

   }

   public void depositSavings(double amt) {

       if (amt > 0) {

           this.savingsBalance += amt;

       }

   }

   public void withdrawChecking(double amt) {

       if (amt > 0) {

           this.checkingsBalance -= amt;

       }

   }

   public void withdrawSavings(double amt) {

       if (amt > 0) {

           this.savingsBalance -= amt;

       }

   }

   public void transferToSavings(double amt) {

       if (amt > 0 ) {

           this.checkingsBalance -= amt;

           this.savingsBalance += amt;

       }

   }

Varvara68 [4.7K]

Answer:

Explanation:

Farmers are always both directly and indirectly connected to each other

Their network is mostly strong

Networks become weak only on the edges (ends) of the river but doesn't completely dimnish

With the available network length, the center of river bank forms the strongest network of all and becomes a key player in defining the balance property of overall network

The network is very well structurally balanced and we can see that through the below image

20 miles 10 20 30 40 50

See attachment file for diagram

Considering the total length of river as 50miles and and the center of the whole length will be at 25th mile. From that point, if we consider a farmer will be be having friends for a length of 20miles both along upstream and downstream.

By this he'll be in friend with people who are around 80% of the total population. As me move from this point the integrity increases and this results in a highly balanced structural network.
