$\sf\qquad\qquad\qquad{\underline{ Food ~in~ space }}$

Explorers and travelers throughout history have had to develop methods for preserving food and carrying enough food for their journeys. This problem was especially difficult during the time when people made long sea voyages on sailing ships. Great explorers like Columbus, Magellan and Cook carried dried foods and foods preserved in salt and brine.

More recently, refrigeration and canning have provided solutions to the problem of food preservation. However, space travel required that new methods be devised for keeping foods edible. Foods taken into space must be light-weight, compact, tasty and nutritious. They must also keep for long periods without refrigeration. A variety of menus consisting of foods similar to those displayed here provided each astronaut with 2500 or more calories per day.

Answer:

Food in space

On earth we have a variety of foods, but we can not enjoy every food in space. Do you know why?In space astronauts eat non-delicious food but some people think the other way around. preparing food in space is complicated for many reasons, some are microgravity, some foods are not perfected for space and some foods do not meet the requirements of space food.

preparing food in space can be very different from earth because of microgravity which makes the food float. According to the text “ no pizza in space” the author states Soft drinks don't work because of microgravity. soda in space is a bit complicated, Because in microgravity the light gas bubbles won’t rush to the top of the liquid to escape.The bubbles of carbon dioxide in carbonated beverages aren't floatable in a weightless environment, so they remain randomly distributed throughout the fluid, even after drinking. astronauts can't sprinkle salt and pepper on their food in space,They just float away because of microgravity. Scientists have made space food better than before and they will make space food better in the future for astronauts.

Some foods are not perfected to go to space because of many reasons. Milk is one of the foods that is not perfected and It is also banned for going into space because milk is dehydrated. According to the text “ No Pizza in Space “ Pizzas have not been perfected yet to go to space.Bread is another food that is not perfected and also banned because the bread crumbs float around, and can fly into an astronaut’s eyes and interfere with important equipment.Ice cream is not perfect to go to space because in space shuttle there is no refrigerator and also scientists have not made an Ice-cream that can go without a refrigerator. Scientists are predicting more food for astronauts as they live longer in space.

Some foods do not meet the requirements of space food because they don't have enough nutrition to provide to astronauts. According to the text “ No Pizza in Space?” the author states that they use caloric requirements based on a World Health Organization equation. The most important thing in developing space foods is making sure that they are tasty, have good nutrient content, and can be easily prepared. Calorie requirements differ for astronauts. An astronaut can choose from many types of foods such as fruits, nuts, peanut butter, chicken, beef, seafood, candy, brownies, etc.Scientists ensure the food that astronauts eat provides them with a balanced supply of vitamins and minerals. In the past space food did not have enough nutrients to provide to astronauts and now it has triple the nutrients to give to astronauts.

In conclusion, preparing food in space is complicated for many reasons, some are microgravity, some foods are not perfected and some foods do not meet the requirements of space food. astronauts need to eat a Nutritionists diet to remain healthy in space as the discover the secrets of the unknown world

4. ABCD below is a rectangle. BE=6x+2 and ED=4x+6. Find the length of AC.

Nikolay [14]

Answer:

28 units

Step-by-step explanation:

ABCD is a rectangle. AC and BD are diagonals intersecting at point E.

Diagonals of a rectangle bisect each other.

$\therefore BE = ED$

$\therefore 6x + 2 = 4x + 6$

$\therefore 6x - 4x= 6-2$

$\therefore 2x= 4$

$\therefore x= \frac{4}{2}$

$\therefore x= 2$

$\therefore 6x + 2= 6*2+2= 12+2= 14$

$\therefore BE= 14\: units$

$\because BD = 2BE$

$\therefore BD = 2(14)= 28\: units$

$\because AC = BD$ (diagonals of a are equal in measure)

$\therefore AC = 28\: units$

I need help with this please and thank you.

SashulF [63]

Answer: I believe the answer would be as follows:

8.431 grams

5.46 seconds

980 meters

900 miles

Step-by-step explanation:

it would first be which has the largest number after the decimal point, so if there’s three it goes first (0.12*3*). Then you would pick the one that is the smallest form of measurement, which would be meters in this case.

Hope this helped!

Identify the transformations that describe the graph of an odd function. Select all that apply.

Marianna [84]

A function is said to be an odd Function is the graph of the function is symmetric with respect to the origin. A function is odd if and only if f(–x) = –f(x).

The transformations that describe the graph of an odd function includes:

1.) 180° rotation around the origin

2.) reflection over the line y = x
