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

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.

Answer: temperature goes with the heat can you follow add me and heart me like me and can I get my 20 points

Explanation:

Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy

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.

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.

Answer:

Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question we have

momentum = 8 × 2

We have the final answer as

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

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.
