Answer:
E. All of the Above
Explanation:
By doing any kind of exercise or physical activity, you are increasing your overall health. Your muscle strengthen because of the jumping and movement of arms. You are more alert because you have to time each jump right in order to keep going. By breathing evenly while jumping, you do help your Cardiorespiratory fitness as well. And of course, you increase your athletic ablility over all with much endurance and practice.
The frictional force is oposing the force that we apply to this mass. Therefore the overall force is
![F_{total}=F_{applied}-F_{friction}=20-15 =5 (Newton)](https://tex.z-dn.net/?f=F_%7Btotal%7D%3DF_%7Bapplied%7D-F_%7Bfriction%7D%3D20-15%20%3D5%20%28Newton%29)
The second principle of physics tells us that the acceleration of a mass is direct proportional to the applied force, the mass of that object being the proportionality constant.
![F=m*a](https://tex.z-dn.net/?f=F%3Dm%2Aa)
Hence
(C)Green and blue
Just took a test in science with this!
Answer:
linear speed = 595.706 miles/hours
Explanation:
to find the linear speed of the moon (Express your answer in miles per hour)
Given
radius of the moon = 1737.1 km = 1079.4 mile (a constant value)
The mean distance of a moon from a planet is 2.82 * 10^ 5 miles
therefore, the total distance from the moon to the planet =
=1079.4 + 2.82 * 10^ 5 = 283,079.4 miles
Assuming that the orbit of the moon around the planet is circular and that
1 revolution takes 21.6 days = 21.6*22hours = 475.2 hours
(1 day is 22 hours),
therefore, the time taken for the moon to move round the planet is = 475.2 hours
then,
linear speed = Distance/time
=283,079.4 miles /475.2 hours = 595.706 miles/hours
Its when we go down the group not up because the no. of electrons increases which results in increased no. of shells.
