A train traveling along a straight track with a speed of 2 ms-1, begins to accelerate with a=2/v ms^-2where v is in ms-1. Find its velocity after 3 seconds in m/s. |
|
Answer» Answer: 8ms-1 Explanation: The acceleration of an object can be calculated by the FORMULAR A=(vf-vi)/Tf-Ti) Where A =Acceleration Vf=Final VELOCITY Vi= Initial velocity Ti=Initial Time Tf =Final Time In this case, A=2/V MS -2 Vi=2ms-1 Ti-Tf we are given as 3 SECONDS Therefore to find Vf after three seconds, We assume that; Vf= X Replacing Vf in the formular 2=(x-2ms-1)/3 6=x-2 x=8 Replacing x with Vf Vf=8

For obtaining natural fibres either plants are cut down or animals are harmed in some way or the other. Write a essay on increasing the usage of synthetic fibers to protect plants and animals. |
|
Answer»
We need to harm PLANTS and animals to obtain NATURAL fibres which can cause an unbalance in the eco SYSTEM. Therefore we should use more and more synthetic fibres so that we do not need to harm plants and animals. Synthetic Fibers are no made USING plants and animals so we should increase the use of these fibres. Synthetic fibres can dry quickly and are durable and long lasting compared to natural fibres. Synthetic FIBRE are available easily and are cheaper compare to that of natural fibres. |

How she can exchange the nutrative value of food |
|
Answer» Food Exchange (US) The Food Exchange was devised by the American Dietetic Association and American Diabetes Association The Food Exchange was devised by the American Dietetic Association and American Diabetes Association In 1950, the US Food Exchange list was DEVELOPED by the American Dietetic Association, the American Diabetes Association and the US Public Health Service to target meal planning problems. The aim of this concept was to provide people with diabetes with the tools to incorporate consistency in their meal planning and include a wider variety of foods. Carbohydrate exchanges are 15g PER portion, which is different to the United Kingdom carbohydrate portions of one per 10g. You should not change to another method of counting food values if you use the US Food Exchange as this may require changing your medication if you have diabetes. What is food exchange? The word exchange refers to the food items on each list which may be substituted with any other food item on the same list. One exchange is approximately equal to another in carbohydrate, calories, protein and fat within each food list. The last published version of the Exchange Lists for Meal Planning was published by the American Diabetes Association and the American Dietetic Association in January 2013. These food exchange lists can be used to assess serving sizes for each food group. Diabetic exchange A diabetic exchange diet is designed to allow you easy control over the amount of sugar and cholesterol you allow into your body. A successful diabetic exchange diet will help to control your weight, BMI (Body Mass Index) and your sugar levels. It is necessary to carefully measure food in a diabetic exchange diet, and it is generally recommended to eat three meals and one snack per day. The diabetic exchange divides foods into six specific groups, and measures food per serving size. Try the Food Exchange Calculator A balanced diet will take the correct proportion from each food group, and your dietician will tell you the number of servings that should be eaten from each food group per day. Food in the same group may be exchanged to give variety. Be sure to carefully measure or weigh each food and drink item. How does the diabetic exchange work? The diabetic exchange system is flexible and centred around selecting foods BASED around your calorie intake. To work out your calorie level and how many servings of each food group you can have per day, you will need to calculate your BMI (Body Mass Index). If you in the normal BMI range, you are generally allowed between 1,800 and 2,000 calories per day. For those in the overweight BMI range, this is reduced to roughly 1,600 and then between 1,200 and 1,400 for people in the obese range. Upon working out your BMI and calorie allowances, you should then assess how much carbohydrate you can have in your daily diet. This can be done by multiplying your daily calorie intake by .43 and then DIVIDING that number by four. Exchange = ([Daily Calorie Intake] * .43)/4 An example of this would be 1600 x .43 = 688 / 4 = 172 grams of carbohydrate, which would be your daily allowance. Diabetic Exchange food groups This list is certainly not comprehensive, but it does contain a wide variety of foods that conform to the diabetic exchange diet. Some foods may not be included that are perfectly alright to eat, but patients on a diabetic exchange diet should avoid eating foods in the ‘Prohibited List’. However, because a food does not appear in the prohibited list, it is not necessarily alright to eat. Bread and Starch Each serving from this list contains 15 grams of carbohydrate, 0-3 grams protein, 0-1 gram fat and 80 calories.

These silkworms FEED on FRESH mulberry leaves the silkworm grows in size and then becomes a pupa. In the pupa stage, it weaves a net to hold itself. It then swings its HEAD from side to side, secreting a fiber that hardens on contact with air. This fiber is made of a protein and becomes the silk fiber. The CATERPILLAR covers itself completely with silk fiber and turns into a pupa, this covering is known as the cocoon. The moth continues to develop within the cocoon.
