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.

In a tug of war , two teams pull on the rope with a certain force. If team A pulls on it with a force of 225 N and team B pulls on it with a force of 360 N, what is the magnitude of the resultant force on the rope?
Answer:
135 N
Explanation:
Given that:
In a tug of war, team A pulls the rope with a force of 225 N; &
Team B also pulls with a force of 360 N
The magnitude of the resultant force is the difference between the two forces since they are positioned in the opposite direction.
Thus;
The magnitude = 360 N - 225 N
So, magnitude of resultant force on the rope = 135 N

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

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.

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.

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.

Planets A and B have the same mass, but planet A is half the size of planet B.
Which statement correctly explains the weight you would experience on each
planet?
A. You would weigh the same on both planets because your mass
would be the same on both.
B. You would weigh less on planet A because the distance between
you and the planet's center of gravity would be smaller.
C. You would weigh more on planet A because the distance between
you and the planet's center of gravity would be smaller.
D. You would weigh the same on both planets because the masses
of the planets are the same.
Answer: C
Explanation: I just finished the test on A P E X :)
Planets A and B have the same mass, but planet A is half the size of planet B, hence you would weigh more on planet A because the distance between you and the planet's center of gravity would be smaller, so option C is correct.
What is mass?A fundamental characteristic of an object, its inertia is quantified by its mass, which is a basic indicator of the volume of substance inside the thing. Because mass is such a fundamental quantity and is difficult to define in terms of another, definitions of it frequently appear circular.
It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.
Therefore, You would weigh more on planet A because the distance between you and the planet's center of gravity would be smaller.

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.

The variables with the subscript "i" refer to the initial masses (m) and velocities (v) of the shark and fish.
[tex]m_{1,i}[/tex] = 10 kg
[tex]m_{2,i}[/tex] = 0.5 kg
[tex]v_{1,i}[/tex] = 5 m/s
[tex]v_{2,i}[/tex] = 0 m/s
The variables with "f" refer to the final masses and velocities. Use the law of conservation of momentum to calculate these. The law says that the total momentum of the shark and fish before the fish is eaten should be equal to the momentum after the fish is eaten. We have
[tex]m_1v_1[/tex] = (10 kg) (5 m/s) = 50 kg • m/s
[tex]m_2v_2[/tex] = (0.5 kg) (0 m/s) = 0 kg • m/s
so the total momentum before the fish gets eaten is 50 kg • m/s.
When the shark eats the fish, its mass increases by 0.5 kg. So
[tex]m_{1,f}v_{1,f}[/tex] = (10.5 kg) [tex]v_{1,f}[/tex] = 50 kg • m/s
Solve for [tex]v_{1,f}[/tex] by dividing both sides by 50.5 kg to get
[tex]v_{1,f}[/tex] = (50 kg • m/s) / (50.5 kg) ≈ 4.76 m/s
