A runner is jogging in a straight line at a steady Vr= 3.4km/hr. When the runner is L=8km from the finish line, a bird begins fl
Lynna [10]

Answer:

The cumulative distance that the bird travel is 13.33 Km

Explanation:

Given that,

Velocity of runner = 3.4 km/hr

Distance = 8 km

Velocity of bird = 17 km/hr

Let x is the distance from the origin where the runner run into the bird

We need to calculate the value of x

Using time of runner and bird

t_{r}=t_{b}

\dfrac{d_{r}}{v_{r}}=\dfrac{d_{b}}{v_{b}}

Put the value into the formula

\dfrac{x}{3.4}=\dfrac{8+(8-x)}{17}

17x=3.4\times8+3.4(8-x)

17x=27.2+27.2-3.4x

17x+3.4x=54.4

x=\dfrac{54.4}{20.4}

x=2.67

We need to calculate the cumulative distance that the bird travel

Using distance of bird

d_{b}=16-x

Put the value into the formula

d_{b}=16-2.67

d_{b}=13.33\ km

Hence, The cumulative distance that the bird travel is 13.33 Km

A circular rod with a gage length of 3.5 mm and a diameter of 2.8 cmcm is subjected to an axial load of 68 kN . If the modulus o
Crank

To solve this problem, we will apply the concepts related to the linear deformation of a body given by the relationship between the load applied over a given length, acting by the corresponding area unit and the modulus of elasticity. The mathematical representation of this is given as:

\delta = \frac{PL}{AE}

Where,

P = Axial Load

l = Gage length

A = Cross-sectional Area

E = Modulus of Elasticity

Our values are given as,

l = 3.5m

D = 0.028m

P = 68*10^3 N

E = 200GPa  

A = \frac{\pi}{4}(0.028)^2 \rightarrow 0.0006157m^2

Replacing we have,

\delta = \frac{PL}{AE}

\delta = \frac{( 68*10^3)(3.5)}{(0.0006157)(200*10^9)}

\delta = 0.001932m

\delta = 1.93mm

Therefore the change in length is 1.93mm

Un texto de opinión sobre la situación actual del rol de la mujer, el trabajo y las situaciones de violencia en el contexto de P
docker41 [41]

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.
