Answer:

Meteoroids

Explanation:

Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust.

The term by which an asteroid called is smaller than a couple of meters wide is a meteorite.

A meteorite is a small group of rocks and debris. They are made by the collection of dust and small pebbles. They are smaller than asteroids, and they are formed in outer space, and they fall on earth from outer space, and when they fall into the earth with that great speed, they attain heat.

Meteorites also consist of metals, like nickel, carbides, sulfides, etc. It has been said that in old times the meteorite that contain iron, fall into the earth and the iron from them melted into the core of the earth. They are of different shapes and sizes.

Thus, the term by which an asteroid called is smaller than a couple of meters wide is a meteorite.

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

In a collision, both objects are subjected to a force that causes them to accelerate. Despite the fact that the forces are equal in magnitude and direction, the least massive item experiences the highest acceleration. When two objects of identical mass collide, they both experience the same acceleration.

A collision is a brief encounter between two or more bodies that results in a change in motion of the bodies involved as a result of internal forces acting between them. Forces are involved in collisions (there is a change in velocity ).

Answer:

(Δa/a +Δb/b) × 100

Explanation:

Y= a/b

So, maximum percentage error

Δy/y = ( Δa/a + Δ b/b) × 100

An applied force applied causes a body such as the spacecraft to move. The magnitude of the force determines the change in the velocity

What will happen to the spacecraft is given by option C. from among the possible question options.

C. The spacecraft will begin to move and it will continue moving until it is stopped by an equal and opposite force

Reason:

The possible question options obtained from a similar question includes;

A. The spacecraft will move for some time then stop slowly

B. Air resistance will prevent the spacecraft from moving

C. The spacecraft will begin to move and the motion will continue until a force equal and opposite to the applied force stops it

D. The quick push will not cause the spacecraft to move, as a quick push works on Earth only

The state of the space craft = Motionless

Location of the spacecraft = Deep space

Type of force applied = Quick push

The statement that describes what will happen = Required

Solution;

Let F, represent the force applied, and let Δt be the duration of the applied force, we have;

The impulse of the force, F × Δt = m·(v₂ - v₁)

Where;

m = The mass of the spacecraft

v₁ = The initial velocity of the spacecraft = 0

v₂ = Final velocity of the spacecraft

Plugging in v₁ = 0, gives;

F × Δt = m·v₂

The space craft is given a velocity, v₂, and according to Newton's First Law of Motion, it continues moving in a straight line until another force acts on it

Therefore, the correct option is option C. The spacecraft will begin to move and the motion will continue until it is stopped by an equal and opposite force

Answer:

definition: the moving of something from its place or position.

Explanation:

though moving around a track they will always end in the same place therefore there is no displacement from the beginning position

There is no displacement from the starting position because they will always wind up in the same place as they started.

Displacement is defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into account both the direction of the motion and the magnitude of the changing position. Displacement may be zero, positive, or negative.

The initial and final positions are needed in order to calculate displacement because displacement does not provide comprehensive information on the full path length.

The displacement is the shortest distance from the starting point to the finish point, the athlete starts from the start line and reaches the finish line after running through the whole track, but the starting point and the finishing point are the same, so the displacement is zero.

Therefore, the displacement of the athlete running through the track is zero for a complete race.

Answer:

The moon is being pulled to the earth by gravity, so the net force makes a circular pattern.

Explanation:

The force of gravity is a force that pulls objects toward the centre of the earth. The acceleration due to gravity of the moon is about 1.6 metre per second square which is comparatively smaller than the earth's 10metre per second. Therefore, the moon isn't completely pulled to the centre of the earth, but orbits around the earth

a) V= 13m/s at 24 degrees

X component of velocity Vx= V*cos24 =11.876 m/s

distance =4.2 meter

time =distance/speed =4.2/11.876 =0.3537 s

b) Vertical component of speed = Vy=vsin24=

The lens can sharpen the curvature of its front and back surfaces, increasing its focusing power.

Explanation:

A lens can change its refractive power through sharpening of the curvature of its front and back surfaces, thereby increasing its focusing power.

The optical power of a lens is the degree to which the lens is able to converge or diverge light.

The optical power of a lens is measured in Diopters, and obtained by taking the reciprocal of the focal length in meters.

P = 1/F

The relation of uniform movement allows to find the result for the distance that descended when crossing the river is:

           d = 180 m

Given parameters

To find

Velocity is a vector magnitude, it has modulus and direction, therefore vector algebra must be used.

The velocities are constant, let's use the uniform motion relation.

           v = [tex]\frac{d}{t}[/tex]  

In the attached we have a diagram of the movement.  Let's calculate the time to cross the river.

          [tex]v_r = \frac{x}{t}[/tex]  

            [tex]t= \frac{x}{v_r}[/tex]  

            t = [tex]\frac{120}{8.0}[/tex]  

            t = 15 s

The time is a scalar it is the same for the two movements, let's find how much it has descended in this time.

          [tex]v_m = \frac{d}{t}[/tex]  

           d = [tex]v_m t[/tex]  

           d = 12.0  15

           d = 180 m

In conclusion, using the uniform motion relationship we can find the result for the distance that descended when crossing the river is:

           d = 180 m

The gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.

Weight is the force exerted by earth on a body on the surface of earth. Mathematically -

W = mg

Given is a 53 kg object standing on the surface of the Earth.

The gravitational force acting on the body will be same as it weight and will be directed towards the center of earth. Using the formula for weight -

W = mg = 53 x 10 = 530 N                [taken g = 10 m/s²]

Therefore, the gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.

Answer:

Explanation:

because if a tennis ball hit a tennis racket still it would not go anywhere. with the tennis ball hitting the moving racket it will go further

One that is in motion because both the ball and the racquet will contribute momentum.

Thus, option (c) is correct.

Newton's third law of motion states that for every action, there is an equal and opposite reaction.

When the tennis ball hits a tennis racquet in motion, both the ball and the racquet will exert forces on each other in opposite directions.

This interaction will result in a transfer of momentum from the racquet to the ball and vice versa, potentially giving the ball a greater momentum and therefore potentially causing it to go farther.

Thus, option (c) is correct.
