Weight is the gravitational force of attraction between the Earth and the horse. The correct option is C.

Weight is a measure of the force with which the Earth's gravity attracts the mass of an object. The weight of an object depends on its mass of the object and the strength of the gravitational field it is in. On Earth, the weight of an object is directly proportional to its mass and acceleration due to gravity.

Therefore, the weight of the horse is the force with which the Earth attracts the mass of the horse, and it is proportional to the mass of the horse and the strength of the gravitational field at the horse's location. The other options do not accurately describe weight.

Answer:

The statement is true

Explanation:

The complete question is

Light bends when it changes the medium because the dielectric permittivity of the material makes the path more hard to penetrate

True or False

Solution

The given statement is true as it is the dielectric permittivity of the material  which does not allow light to pass through it easily.

The medium decrease the amplitude of light and hence induces change in direction without altering its velocity or frequency.

Explanation:

Gamma decay cannot result in the transmutation of the parent nucleus. Therefore, option (A) is correct.

Gamma decay can be described as the emission of electromagnetic radiation of a high frequency that is a high energy, giving out excess energy to stabilize the unstable nucleus. Gamma rays can be defined as a stream of high-energy radiation given off by a nucleus undergoing radioactive decay.

Gamma decay can be described as the nucleus dropping from a higher energy level to a lower energy level through the emission of high-energy photons.

Therefore, the gamma-ray emitted is also of very high energy, just like x-rays. Due to their high energy of gamma rays, they are penetrating and thereby dangerous to biological life forms.

In the transmutation of an element, one element is converted into another element. In gamma decay, the transmutation of the parent nucleus does not take place. As the gamma-ray high-energy particles are represented as ⁰γ₀.

Answer:

W = 1,176 10⁴ J

Explanation:

Work is defined by

         W = F . d

bold indicates vectors

          W = F d cos θ

In this case we must find the force to raise the load and the branch, suppose that the rate of rise is constant, this is the most common case

       Σ F = 0

       F - W₁ - W₂ = 0

where W1 is the weight of the branch and w2 wl weight of the load

       F = (m₁ + m₂) g

This force is directed upwards and the displacement is upwards, therefore the angle is zero and the cos 0 = 1

we substitute in the work equation

        A = (m₁ + m₂) g d

let's calculate

        W = (40 + 20) 9.8 20

        W = 1,176 10⁴ J

This is the work done by the external force

Answer:

His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.

Answer:

n₂ = 1.459

Explanation:

This is a refraction exercise

          n₁ sin θ₁ = n₂ sin θ₂

where n₁ and n₂ are the refractive indices of the incident and refracted medium, respectively

In the exercise they indicate that the incident medium is the air that has a refractive index n1 = 1

         n₂ = n₁    [tex]\frac{sin \ \theta_1 }{sin\ \theta_2 }[/tex]

let's calculate

        n₂ = 1   [tex]\frac{ sin \ 45}{sin \ 29}[/tex]

        n₂ = 1.459

The absolute index of refraction of the medium X in which the monochromatic ray of light enters from air is 1.459.

According to the Snell's law, the ratio of index of reflection of the different material is equal to the ratio of incident sine angle and reflective sine angle. It can be given as,

[tex]\dfrac{n_1}{n_2}=\dfrac{\sin\theta_2}{\sin\theta_1}[/tex]

Here (n₁ and n₂) are the index and reflective index and  (θ₁ and θ₂) are the incident and reflected angle.

A monochromatic ray of light (f = 5.09 x 1014 Hz) travels from air into medium X.

The angle of incidence of the ray in air is 45.0° and the ray's angle of refraction in medium X is 29.0°.

As, it is known that the index of reflection of air is 1. Thus, by the Snell's law, the absolute index of refraction of medium X is,

[tex]\dfrac{1}{n_x}=\dfrac{\sin(29)}{\sin(45)}\\n_x=1.459[/tex]

Thus, the absolute index of refraction of the medium X in which the monochromatic ray of light enters from air is 1.459.

The speed of the volleyball with a mass of 0.28 kg and height of 12 m will be 15.336 m/s.

Speed is the rate of change of distance of an object with respect to time. Speed is a scalar quantity as it has only magnitude and no direction. The SI unit of speed is meter per second (m/s).

PE = KE

Potential Energy = Kinetic energy

mgh = 1/2 mv²

where, m is the mass of object,

g is the acceleration due to gravity,

h is the height of the object,

v is the speed of the object

gh = 1/2v²

2gh = v²

v = [tex]\sqrt{2gh}[/tex]

v = [tex]\sqrt{2(9.8)(12)}[/tex]

v = [tex]\sqrt{235.2}[/tex]

v = 15.336 m/s

Therefore, the speed of the volleyball will be 15.336 m/s.

Answer:

(i) El coche recorre 180 kilómetros.

(ii) El coche decelera a razón de 2.5 metros por segundo al cuadrado.

Explanation:

El problema se divide en dos partes. La primera es el coche viajando a velocidad constante y la segunda consiste en una decelaración hasta alcanzar el reposo.

Primera parte - Viaje a velocidad constante

La distancia recorrida por el coche se calcula mediante la siguiente ecuación cinemática:

[tex]x = v\cdot t[/tex] (1)

Donde:

[tex]x[/tex] - Distancia recorrida, en kilómetros.

[tex]v[/tex] - Velocidad, en kilómetros por hora.

[tex]t[/tex] - Tiempo, en horas.

Si sabemos que [tex]v = 90\,\frac{km}{h}[/tex] y [tex]t = 2\,h[/tex], entonces la distancia recorrida por el coche es:

[tex]x = v\cdot t[/tex]

[tex]x = 180\,km[/tex]

El coche recorre 180 kilómetros.

Segunda parte - Deceleración

Asumiendo que la deceleración del coche es constante, se determina mediante la siguiente ecuación cinemática:

[tex]a = \frac{v-v_{o}}{t}[/tex] (2)

Donde:

[tex]v_{o}[/tex] - Velocidad inicial, en metros por segundo.

[tex]v[/tex] - Velocidad final, en metros por segundo.

[tex]t[/tex] - Tiempo, en segundos.

Si sabemos que [tex]v_{o} = 25\,\frac{m}{s}[/tex], [tex]v = 0\,\frac{m}{s}[/tex] y [tex]t = 10\,s[/tex], entonces la deceleración experimentada por el coche es:

[tex]a = -2.5\,\frac{m}{s^{2}}[/tex]

El coche decelera a razón de 2.5 metros por segundo al cuadrado.

Explanation:

[tex]period = 1 \div frequency[/tex]

frequency is given

Answer:

[tex]-2.5\ \text{m/s}^2[/tex]

[tex]-5500\ \text{N}[/tex]

Explanation:

m = Mass of car = 2200 kg

t = Time = 10 s

v = Final velocity = 0

u = Initial velocity = 25 m/s

a = Acceleration

From the kinematic equations of linear motion we have

[tex]v=u+at\\\Rightarrow a=\dfrac{v-u}{t}\\\Rightarrow a=\dfrac{0-25}{10}\\\Rightarrow a=-2.5\ \text{m/s}^2[/tex]

Acceleration of the car is [tex]-2.5\ \text{m/s}^2[/tex]

Force is given by

[tex]F=ma\\\Rightarrow F=2200\times (-2.5)\\\Rightarrow F=-5500\ \text{N}[/tex]

Net force required to produce the acceleration is [tex]-5500\ \text{N}[/tex].

Answer:

n = 1/5 and m = 3/5

Explanation:

The given quantity is :

[tex]A=B^nC^m[/tex]

Where

The dimension of [A] = [LT]

The dimension of [B] = [L²T⁻¹]

The dimension of [C] = [LT²]

We need to find the dimensions of n and m values.

Using dimensional analysis,

[tex][LT]=[L^2T^{-1}]^n[LT^2]^m\\\\\ [LT]=L^{2n}T^{-n}\times L^mT^{2m}\\\\\ [LT]=L^{2n+m}T^{2m-n}[/tex]

Comparing both sides,

2n+m=1 ....(1)

-n+2m=1 ,.....(2)

Solving (1) and (2), we get :

n = 1/5 and m = 3/5

Hence, this is the required solution.

Answer:

–0.11 N.

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 6.1 g

Initial velocity (u) = 350 m/s

Time (t) = 0.32 mins

Final velocity (v) = 0 m/s

Force (F) =?

Next, we shall convert 0.32 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

0.32 mins = 0.32 × 60 = 19.2 s

Next, we shall determine the acceleration of the the bullet. This can be obtained as follow:

Initial velocity (u) = 350 m/s

Time (t) = 19.2 s

Final velocity (v) = 0 m/s

v = u + at

0 = 350 + (a × 19.2)

0 = 350 + 19.2a

Collect like terms

0 – 350 = 19.2a

–350 = 19.2a

Divide both side by 19.2

a = –350 / 19.2

a = –18.23 m/s²

Next, we shall convert 6.1 g to Kg.

1000 g = 1 Kg

Therefore,

6.1 g = 6.1 g × 1 Kg / 1000 g

6.1 g = 0.0061 Kg

Finally, we shall determine the force. This can be obtained as follow:

Mass (m) = 0.0061 Kg

Acceleration (a) = –18.23 m/s²

Force (F) =?

F = ma

F = 0.0061 × –18.23

F = –0.11 N

NOTE: The negative sign indicates that the force is in opposite direction.

–0.11 N.
