a soccer ball is rolled across four different surfaces:a tile floor,a paved road,a grassy field,and a cement side walk.which surface will slow the movement of the soccer ball the most?explain why.

Answers

The grassy field would slow down the soccer ball the most because it is not a very flat smooth surface. The grass is very thick and kind of grabs the ball.The paved road, tile floor, and cement sidewalk are flat and smooth
the grass would slow the ball down because of friction and the road, sidewalk, and tile floor would make the ball go faster because the surface is smooth.

While surveying his apple trees, a farmer discovers a particular tree that produces apples with perfect size, color, and flavor. To reproduce this plant, he removes a twig from the s tree and attaches it to the stem and root system of a growing apple tree in a process called grafting. The tree will continue to grow and will later produce apples.Why does he use this method instead of planting an apple seed from the tree with ideal apples?

You and a group of friends are spending your vacation hiking through the mountains. It is cold in the mountains. You will be expending a lot of energy while hiking and you will need plenty of energy to help keep you warm. You should pack foods high in ________ to provide the most energy or kilocalories per gram of food. A) carbohydrates B) lipids (fats) C) proteins D) sugars

Answers

Answer:

The correct answer will be option-B (fats or lipids)

Explanation:

The oxidation of fatty acids provides the most abundant energy that is 9 kilocalories per gram of food as compared to proteins and the carbohydrate which provides only 4 kilocalories per gram of food.

If a person wants to go hiking then, the person would keep the food rich in fatty acids which will provide a high amount of energy and a large amount of heat through the process of respiration.

Thus, Option-B is the correct answer.

C. proteins
