Answer:

one object exerts a force on a second object

Explanation:

i just took this

The net force is in the direction of the larger force. If we take that direction to be positive, then the net force has a magnitude of

68.8 N - 26.5 N = 42.3 N

Use Newton's second law to solve for the acceleration:

F = m a

42.3 N = (21.2 kg) a

a = (42.3 N) / (21.2 kg)

a ≈ 2.00 m/s²

An action reaction pair of forces exists between : ( A ) The aerialist arms and legs

Action-reaction pair of force comprises of the force that acts on the object as a action force and the force experiened by the object due to newton third law of motion as the reaction force. Therefore in the diagram an action reaction pair of forces can be experienced between the aerialist arms and legs

Actually Welcome to the Concept of the Rays of light.

Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.

Thus Option c.) is correct.

C.) is the Answer.

The angle of reflection given the incident ray from the given diagrams is option C.

When a light ray strikes the shining surfaces, the part of the light gets refracted. The bouncing back of the light is called reflection. When the light strikes the surface is called an incident ray.

When the light ray incident on the surface, the light returns back to the same medium is called reflection. The laws of reflection are, the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal takes place in the same plane. The speed of light remains the same in the process of reflection.

The reflected light ray changes the path of direction in the same medium. When a light ray enters from one medium to another, the speed of light gets decreases.

Thus, the ideal solution is option C.

A magnetic material, such as iron are two possible materials that could be in the door. So, the correct option is (A).

A magnet is defined as a material or object that produces a magnetic field where the magnetic field is invisible but is responsible for the most notable property of a magnet: a force that attracts metals such as iron, steel, nickel, cobalt, among others. attracts or repels ferromagnetic materials, etc. and other magnets.

Magnet is describe as the object which is capable of producing magnetic field and attracting unlike poles and repelling like poles. When the magnet is dipped in iron filings, we see that the iron filings stick to the ends of the magnet due to magnet attraction being maximum at the ends of the magnet, hence the ends are known as the poles of the magnet .

Thus, a magnetic material, such as iron are two possible materials that could be in the door. So, the correct option is (A).

Answer:

Since there is no gravity or friction in Tanya's world, according to Newton's first law she will keep moving at a constant speed.

Explanation:

Newton's First Law, or also called the Law of Inertia, postulates that every body that is not subjected to any interaction (free or isolated body) remains at rest or moves with constant speed. In other words, it is not possible for a body to change its initial state (whether of rest or motion) unless one or more forces intervene.

In this law then the net force (Σ F) applied on a body is equal to zero and explains that to modify the state of motion of a body it is necessary to act on it.

Tanya randhawa is standing on top of a train traveling at 7 km / sec and the train collides with a cow and comes to a complete stop. Since there is no gravity or friction in Tanya's world, according to Newton's first law she will keep moving at a constant speed.

Explanation:

The particles will have more space between them and will be moving at higher speeds as steam compare to water.

The quantity of heat (in joules or calories) per mole or unit mass of the substance undergoing a change in state is the typical way to represent latent heat.

The latent heat involved in melting solids or freezing liquids is referred to as the "heat of fusion," while the latent heat involved in vaporizing solids or liquids or condensing vapor is referred to as the "heat of vaporization."

When water boils at 100°C and turns into steam, water vaporizes into steam by absorbing heat of vaporization. This heat energy remains in the steam as kinetic energy and makes their movement fast.

So, The molecules will have more space between them and will be moving at higher speeds as steam compare to water.

By Newton's second law, the net force on the car is

∑ F = m a

where m is the mass of the car and a is magnitude of the acceleration.

The car is slowing down, so the net force opposes the direction in which the car is moving. Vertically, the car is in equilibrium, the net force is entirely due to friction. Taking the direction opposite the car's motion to be negative, we have

- 200 N = (200 kg) (-a)

a = (200 kg) / (200 N)

a = 1 m/s²

If you're also supposed to find the coefficient of kinetic friction, use the fact that the car the vertical forces cancel out, namely

n + (-w) = 0

where n is the magnitude of the normal force and w is the car's weight. The friction force f is proportional to the normal force n by a factor of µ, the coefficient of kinetic friction, such that f = µ n. Then

f / µ = w

(200 N) / µ = (200 kg) (9.80 m/s²)

µ = (200 N) / ((200 kg) (9.80 m/s²))

µ ≈ 0.102

Answer:

Combined kinetic energy =120 joules

Acceleration= [tex]10 m/s^2[/tex]

Explanation:

Given that the mass of the girl= 40 kg.

The mass of the boy= 40 kg.

The mass of the wagon = 20 kg.

The combined velocity of the boy and the wagon, v= 2.0 m/s.

The kinetic energy of any object having mass m and moving with the speed of v m/s, is

K.E.= [tex]\frac 1 2 mv^2[/tex].

Here, the combined mass of the boy and the wagon = 40 + 20 = 60 kg.

So, the combined kinetic energy of the boy and the wagon

[tex]=\frac 12 60 \times 2^2= 120[/tex] J

When a force is applied on the object having the mass m, then

F=ma,

where a is the acceleration produced in the object.

Here, F=500 newtons and m= 50 kg.

so, [tex]500=50\times a[/tex]

[tex]\Rightarrow a = 500/50=10 m/s^2[/tex].

Hence, the combined energy is 120 joules and the acceleration is 10 [tex]m/s^2[/tex].
