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.

A ball with an initial velocity of 2 m/s rolls for a period of 3 seconds. If the ball is uniformly accelerating at a rate of 3 m/s2, what will be the ball’s final velocity?
Answer: 11 m/s
vinitial=2 m/s
time=3 s
acceleration = 3 m/s^2
vfinal = ?
The key here is that it is a constant acceleration, so we can use the constant acceleration equations. The easiest one to use would be:
vfinal=vinitial + a*t
We need vfinal, so algebraically we are ready to put in numbers into the equation:
vfinal=vinitial + a*t = 2 m/s + (3 m/s^2)*(3 s ) = 11 m/s is the final velocity
The ball's final velocity is 11 m/s
From one of equations of kinematics for linear motion
We have that
v = u + at
Where v is the final velocity
u is the initial velocity
a is the acceleration
and t is the time
From the given information in the question
u = 2 m/s
t = 3 secs
a = 3 m/s²
Putting these parameters into the above formula
v = u + at
We get
v = 2 + (3×3)
v = 2 + 9
v = 11 m/s
Hence, the ball's final velocity is 11 m/s

Your friend wants to lose weight around the belly. Your friend is planning to do crunches every day to lose the weight, but is not planning on doing any other exercises. Do you think this strategy will be effective? Why or why not? What can your friend do to increase the pace of weight loss? Explain your answer. Please hurry I need a paragraph!!!
But I will put it in my own words so it won't be plagerism!
Answer:
i don't think it will work
Explanation:
because in order to lose weight, you have to do more than one stretch because weight loss takes multiple steps and not just one exercise, it would also involve you to eat healthy and to increase the pace, your friend could go running, do yoga, eat healthier, drink more water, and do more than just a core workout and etcetera.
7. The night of desest is very cold and the day is very
hot
Give reason
Answer:
1) Sand cannot hold the heat. It acts like a mirror to the sun. During the daytime, it stays warm, and when the Sun is absent it loses all its heat making the nights colder. There's nothing in the desert that can either absorb heat from the sun or hold it on the surface when the sun is set.
2) Deserts are hot primarily because of a lack of water. When the sun shines on the ground, all of the absorbed sunlight goes into raising the ground's temperature. DESERTS ARE COLD AT NIGHT:Because of the lack of water in the ground, and little water vapor in the air, most deserts can get quite cool at night.
3) The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night. The daytime temperature averages 38°C while in some deserts it can get down to -4°C at night. The temperature also varies greatly depending on the location of the desert.
You are in a room that has three switches and a closed door. The switches control three light bulbs on the other side of the door. Once you open the door, you may never touch the switches again. How can you definitively tell which switch is connected to each of the light bulbs?

If you neglect air resistance, the horizontal component of a projectile A. Is always changing B. Remains constant throughout the flight C. Increases, goes to zero, then increases D. Depends on who threw it
Answer:
B. Remains constant throughout the flight
Explanation:
If we completely neglect air resistance then the projectile will not have any horizontal resistances to deal with, therefore the horizontal component will remain constant throughout the flight. This would continue to be the case until it meets some form of resistance. Which assuming that everything else is normal would be the case since the force of gravity will push the projectile down (vertical component) until it hits the ground which in that instance would act as an opposing force to the horizontal component as well.

1. Why did Asteroid 2019 OK cause concern among scientists? * The asteroid was not detected until it was extremely close to Earth. It's the largest known near-Earth asteroid ever discovered. The asteroid's path was aimed directly at the moon. The asteroid was too large to be deflected away from Earth
Answer:
The asteroid was not detected until it was extremely close to Earth.
Explanation:
According to data from NASA, the Asteroid named 'Astriod 2019 OK', was detected when it was extremely close to earth with just about an estimated distance of 73,000 kilometers (45,000 miles) from the Earth.
Scientists were concerned at the proximity of this space object to the Earth before it was discovered, and it brought about a cause of concern that since it was not extremely large (estimated 57 to 130 meters wide) it creates a potential for other smaller asteroids to escape detection and struck the earth.
10 Why is it important for basketball players to wear shoes with tread when playing? to increase the speed of the player to decrease the force between the player and the floor to increase friction between the floor and the player's feet to decrease the amount of force needed for the player to move
Answer:
to increase friction between the floor and the player's feet
Explanation:
It is important for basketball players to wear shoes with tread when playing in order to increase friction between the floor and the player's feet.
Friction between the floor and the player's feet will ensure that players do not trip easily during the course of playing. It also helps in such a way that players can stop quickly and run in the opposite direction without losing traction. Without this friction, it would be virtually impossible to play the game.
