Answer:

yes, the model gives a realistic behavior

Explanation:

This describes the inner equilibrium point is a stable node, here it's a center. These are periodic solutions. Populations of the mice and owls are periodic. It describes: when the mice population is lower, the owl population decreases; again the owl is lower so mice got a chance to grow its population; now as sufficient food(mice) is there, the owl population increases; as predator population increases, the prey population decreases; and this continues as a cycle forever.

So, yes, the model gives a realistic behavior.

Answer:

Avoid dirt and sand. Use care when cleaning dirt particles and sand from your digital camera. Do not use canned or pressurized air to clean the sand, as you might just drive the particles into the camera case. Budget-priced camera cases might not be sealed perfectly, making it easier for grit and sand to penetrate the case and cause damage. Gently blow out the grit and sand to avoid this problem. Use care when shooting photos on a windy day at the beach, too, where sand can blow with excessive force. Avoid opening the battery compartment on such days.

Avoid liquids. Keep all liquids away from the camera unless you own a model with a waterproof case.

Avoid touching the lens and LCD. Oils from your skin smudge the lens and LCD, eventually causing permanent damage. Clean the lens and LCD with a microfiber cloth when you see a smudge from your fingertips.

The lens and sun don't mix. Do not point your camera's lens directly at the sun for any length of time, especially with a DSLR camera. Sunlight focused through the lens of the camera could damage the image sensor or even start a fire inside the camera.

Use cleaning liquids with care. Avoid using an excessive amount of cleaning liquid with your camera. In fact, other than stubborn smudges, you should be able to clean the camera with a dry microfiber cloth. If a liquid is needed, place a few drops of the liquid on the cloth, rather than directly on the camera.

Vacuum the bag. Dirt and sand inside your camera bag could damage your camera, so vacuum the bag regularly to keep it clean and protect your camera.

Watch the temperature. Although some cameras are designed to survive harsh temperatures, most cameras are not. Do not leave your camera in a sunny vehicle, where temperatures quickly can exceed 100 degrees Fahrenheit. Avoid leaving the camera in direct sunlight, which can damage the plastic. Finally, avoid extreme cold, too, which could damage the LCD.

Use neck straps and wrist loops. Use neck straps and wrist loops with your camera. If you slip while hiking, or if you lose the grip on your camera near the pool, the straps can save your camera from a potentially disastrous fall.

Store camera properly. If you're not going to use your camera for a couple of months, store it in a low humidity area and out of direct sunlight. Additionally, store the camera without the battery inserted to reduce the risk of corrosion.

Assume that you have an array of integers named arr. The following program segment is intended to sum arr [0]through arr[n−1], w
Paladinen [302]

Answer:

There is only one modification in the above loop i.e. while loop should be like this--

while (i != n)

     {

         sum+=arr[i];   // Line 1, In question segment it is line 2.

          i++;                // Line 2,  In question segment it is line 1.

     }

Output:

Now if the array input is 1,2,3,4,5 then the output is 15.

Explanation:

In the above question, all the line of the segment is right except the body of the loop because--

  • The First line of the loop is increment statement which increments the value of "i" variable from 1 and the value of "i" variable will be 1 in the first iteration of the loop
  • The second line starts to add the value from 1'st index position of the array. Hence the segment gives the wrong answer. It adds the arr[1] to arr[n-1].
  • So I interchanged both lines of the while loop as shown in the answer part. I make the line 1 (In question segment) as line 2(In answer part) and line 2 (In question segment) as line 1 (In answer part).

Now It gives the correct output because it can add arr[0] to arr[n-1].

Andrej [43]

The answer to this is:

A. is a measurement of how well a forecast is predicting actual values.

I have seen this type of tracking signal before, they use this for news forecast to track severe weather such as tornadoes, severe weather, hot weather, winter storms and even hurricanes. This helps the people know what the weather will be like in the next few days or so, so they can get prepared for any storms or hot weather.

it's a interesting technology they have.

Hope this helped :)

Have a great day
