Explanation:

Los derechos de las mujeres fueron conquistados a través de importantes luchas llevadas a cabo por mujeres, como el movimiento feminista que tuvo lugar a fines del siglo XIX, cuyo principal reclamo fue el derecho al voto de las mujeres.

Con el tiempo, las mujeres ganaron más derechos y una mayor participación en el mercado laboral y en puestos importantes de la sociedad. Pero aún queda mucho por cambiar, ya que las estadísticas aún muestran que hay pocas mujeres en posiciones de poder en relación a los hombres, y el salario de una mujer que ocupa el mismo puesto que un hombre es siempre menor.

Dado que la sociedad se concibió a través de parámetros sexistas, lo que continúa en la actualidad, es claro que en la pandemia específicamente que generó crisis económicas en todo el mundo, se vio a una gran cantidad de mujeres perder sus empleos, además del expresivo número de casos de violencia doméstica que se agravaron en el período de aislamiento social.

Así que estos hechos solo demuestran que la lucha por la igualdad de género y los derechos de las mujeres aún están en sus inicios, a pesar de muchos logros que las mujeres aún deben luchar por lo básico, que es el apoyo social y político además de una legislación más estricta que castiga con más rigor a las agresoras. Las mujeres deben estar protegidas por la ley y las instituciones y los medios de comunicación deben abordar más el tema y promover el feminismo como una lucha por la igualdad.

The answer is 150 because we must subtract again, we subtract the reactant (50) from the highest point in the graph, 200 – 50 equals 150.

Answer: Kinetic energy of electron = 7.45 x 10^-16 J We know that Potential difference = Work done per unit charge = Kinetic energy of electron / ( 1.6 x 10^-19 ) = (7.45 x 10^-16) / ( 1.6 x 10^-19) = 4656.25 V

Explanation:

The potential difference between the plates is [tex]4650.43V[/tex]

The Potential difference is also defined as the work done per unit charge.

Work done = kinetic energy = [tex]7.45*10^{-16}J[/tex]

Charge on one electron = [tex]1.602*10^{-19}C[/tex]

Potential difference,

                         [tex]V=\frac{7.45*10^{-16}}{1.602*10^{-19} }=4650.43Volt[/tex]

Hence, the potential difference between the plates is [tex]4650.43V[/tex]

It's the portion of the electromagnetic spectrum that is visible to the human eye.

A book weighing 18.0 N is lifted from the floor and placed on a shelf 1.5 m high.  The minimum amount of work required to accomplish this task is

Work done is the amount energy gained (loosed) in bringing the body from initial position to final position. It is denoted by W and its SI unit is joule(J). i.e. Work(W) is force(F) times displacement(s). W=F× s When a body is displaced with 1 newton of force by 1 m, then we can say that work has been done on the body by 1 joule. Writing for it's dimension, W=F× s Force has dimension [L¹ M¹ T²] Displacement has dimension [L¹] multiplying both the dimensions Force and Displacement we get, dimension of Work [L² M¹ T²].

Given,

Weight F = 18 N

Height h = 1.5 m

Work W = F × h = 18 × 1.5 = 27 J

Image Shadow

2. We are able to see images when light refraction enters our eyes.

In the case of shadow no light enters our eyes.

3. Image contains colour, structure etc. of the object.

Shadow does not give any information about the object as it is colourless

Answer:

We know that an image is a picture of an object while shadow is formed an object comes in between the surface and light. ... The formation of image takes place when the light rays are reflected by an object. The formation of shadow takes place when the light falls on an opaque object.

D: Amplitude

Answer:

s = 45 m

Explanation:

The velocity given in the question is uniform. Hence, the formula for the uniform velocity shall be used here. The formula is given as follows:

[tex]s = vt[/tex]

where,

s = distance traveled away from the brother = ?

v = constant speed = 3 m/s

t = time taken = (0.25 min)(60 s/1 min) = 15 s

Therefore, using these values in the formula we get:

[tex]s = (3\ m/s)(15\ s)\\[/tex]

s = 45 m

Answer:

E = 3456 J

Explanation:

The electrical energy expended in a resistor can be easily calculated by using the following formula:

[tex]E = Pt[/tex]

where,

E = Energy Expended = ?

I = current through 5 ohm resistor = 2.4 A

R = Resistance = 5 ohms

P = Electrical Power = VI

Since,

V = IR (Ohm's Law)

Therefore,

P = (IR)(I) = I²R = (2.4 A)²(5 ohms) = 28.8 Watt

t = time taken = (2 min)(60 s/1 min) = 120 s

Therefore,

E = (28.8 Watt)(120 s)

E = 3456 J

Answer:

The acceleration of the plane is 35.6 meters per square second.

Explanation:

By Newton's Laws of Motion, we know that force ([tex]F[/tex]), in newtons, is directly proportional to acceleration ([tex]a[/tex]), in meters per square second. That is:

[tex]F \propto a[/tex]

If four engines are running simultaneously and each produce the same force, then we find that acceleration of the plane is:

[tex]a_{T} = 4\cdot \left(8.9\,\frac{m}{s^{2}} \right)[/tex]

[tex]a_{T} = 35.6\,\frac{m}{s^{2}}[/tex]

The acceleration of the plane is 35.6 meters per square second.

Answer:

According to Newton's Second Law of Motion :    

Where,

F = Force Applied

m = Mass of the object

a = Acceleration

Now, we will use this law to solve this question.

Given :

Acceleration or a = 15.3 m/s²

Force = 44 N

Mass = ?

Substitute, the given values in the formula.

F = ma

⇒ m = F/a

   m = 44/15.3

m = 2.9 kg
