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.

Answer:

Its b

Explanation:

Hope this helps

Answer:

b

Explanation:

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:

45m

Explanation:

speed= distance/ time

3.0= distance/ 15

*15 on both sides

45m= distance

Answer:

B

Explanation:

Bubbles are a product of a chemical reaction.

The statement which best describes a chemical reaction is the cake rising

as gas bubbles form in the baking cake.

Chemical reaction involves the formation of new chemicals through  

reaction between one or more chemicals.The formation of bubbles indicate

the formation of a new gas and is a characteristic of a chemical reaction.

The formation of a bubble in the cake bake means that a new chemical has

been formed which indicates presence of chemical reaction.

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

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:

Time seem to flow in only one direction because it's from entropy. In tiny physics, time is directionally neutral.

Explanation:

Answer:

objects that store memories heat up as the operate(computers and brains). heat(energy) generation increases entropy. entropy is a measure of disorder. entropy is an irreversible process, so the laws of thermodynamics(law 1. energy can't be created or destroyed law 2. the total entropy must increase) require that such objects can only run in one direction: from past to present

Answer:

Explanation: When a body covers unequal distances in equal intervals of time in a specified direction, the body is said to be moving with a variable velocity. Example: A rotating fan at a constant speed has variable velocity, because of continuous change in direction.

Answer:

No, according to Newton's first law of motion, the block cannot exert a force on itself, and the body will remain at rest unless unbalanced forces act on it

However according to Newton's third and first laws of motion the action of gravity pulling the block down the plane is equal to the reaction force of friction, preventing the motion

Explanation:

According to Newton's third law, the action force of gravity on the block tending to drag the block down along the inclined plane is equal to the reaction force of the frictional force of the inclined plane due to the interactions between the surfaces of the block and the plane which tends to prevent the motion of the block when both the component of the gravitational force down the plane and the frictional force are equal.

EK=1/2Mv^2,EG=mgh

This question involves the concepts of the law of conservation of energy, work done, Newton's Second law of motion, and equation of motion.

The box stops at a distance of "1.02 m".

First, we will use the law of conservation of energy to find out the final velocity when the box reaches the flat part.

[tex]Loss\ of\ Potential\ Energy=Gain\ in\ Potential\ Energy\\mgh=\frac{1}{2}mv^2\\\\2gh=v\\v=\sqrt{2gh}[/tex]

where,

v = speed = ?

g = 9.81 m/s²

h = height = 2 m

Therefore,

[tex]v=\sqrt{(2)(9.81\ m/s^2)(2\ m)}[/tex]

v = 6.26 m/s

Now, we will use the formula of work done to find out the force applied to the box to stop the motion:

[tex]W = Fd[/tex]

where,

W = Work Done = 100 J

F = Force applied = ?

d = displacement = 1 m

Therefore,

[tex]100\ J = F(1\ m)\\F = 100\ N\\[/tex]

Now, we will use Newton's Second Law of Motion to find out the deceleration of the person:

[tex]F=ma[/tex]

where,

m = mass = 5 kg

a = decceleration =?

Therefore,

[tex]100\ N = (5\ kg)a\\\\a=\frac{100\ N}{5\ kg}\\\\a = - 20\ m/s^2[/tex]

negative sign shows deceleration.

Now, we will use the third equation of motion to find the distance at which the box stops.

[tex]2as=v_f^2-v_i^2\\2(-20\ m/s^2)s=(0\ m/s)^2-(6.26\ m/s)^2\\\\s=\frac{40\ m/s^2}{39.24\ m^2/s^2}[/tex]

s = 1.02 m

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.
