Momentum (symbol p) and the equation of momentum is:
p = m*v
1. After the collision, their velocities have switched. This is Newton's third law of motion.
2. The total momentum is conserved.
3. The same thing would happen if the collision is totally elastic.
For 4 and 5.
Using the conservation of momentum equation
m1v1 + m2v2 = m1'v1' + m2'v2'<span />
Answer:
1. "Gage is beginning a low calorie diet, so he eats three servings of chicken for lunch" is equal to C: "Protein contains four calories per gram of fat, so it is a low fat, high energy food."
2. "Walter eats two servings of whole grain pasta the night before running a 5K" is equal to B: "Carbohydrates contain four calories per gram of fat, so they need to come from grains in moderation."
3. "Maggie eats half a candy bar and saves the rest for the next day" is equal to A: "Fatty foods contain nine grams of pure fat and have little nutritional value."
Explanation:
Chicken is a popular, low-fat food that provides an impressive amount of high-quality protein in just one serving. The breast is the leanest part of a chicken. A 3-ounce (85-grams) serving of roasted, skinless chicken breast contains only 3 grams of fat but provides 26 grams of protein (47).
Pasta is a fat-free, low sodium food that can fit right in with a weight loss or management plan. One cup of cooked pasta contains just 200 calories, in addition to valuable vitamins and minerals.
Sweets like candy, soft drinks, syrups, jams, and jellies are made mostly of sugars. Most of these foods do not contain many vitamins or minerals. So they are called "empty calorie" foods. Fats, oils and sweets are not bad foods.
The telescope has the ability to enlarge an image and depends on the combination of lenses used.
Explanation:
Eyepiece performs magnification. The size of primary lens or primary mirror determines the Light gathering power. The main functions of telescope are light gathering, resolution and magnification.
The light gathering power has the ability of a telescope to collect more light than human eye. The purpose of telescope is to focus photons.
