This is something very complex to explain and your diagram isn't shown so it really depends on what it looks like before Anyone will be able to answer this question. If you will post the diagram I will help you to the best of my ability.

A block of mass 0.404 0.404 kg is hung from a vertical spring and allowed to reach equilibrium at rest. As a result, the spring
VARVARA [1.3K]

To solve this problem it is necessary to apply the concepts related to the Force from Hook's law as well as the definition of the period provided by the same definition.

We know that the Force can be defined as

F = xk \rightarrow mg = kx \Rightarrow k = \frac{mg}{x}

Where

k = Spring constant

x = Displacement

g = Gravity

m = mass

At the same time the period of a spring mass system is defined as

T = 2\pi \sqrt{\frac{m}{k}}

Where

m = Mass

k = Spring constant

Our values are given as,

m = 0.404kg

x = 0.666m

Replacing to find the value of the Spring constant we have that

k = \frac{mg}{x}

k = \frac{(0.404)(9.8)}{0.666}

k = 5.944N/m

Now using the formula of the period we know that

T = 2\pi \sqrt{\frac{m}{k}}

T = 2\pi \sqrt{\frac{0.404}{5.944}}

T = 1.638s

Finally, if the oscillation was 0.359m

The maximum height will be determined by the total length of that oscillation being equivalent to

h=2a

h = 2*0.359

h = 0.718m

Metal sphere A has a charge of -2 units and an identical sphere B has a charge of -4 units. If the spheres are brought into cont
shusha [124]

Answer:

 q1 = q₂=  -3

therefore each sphere has the same charge of -3 untis

Explanation:

The metallic spheres have mobile charge, so when the two spheres come into contact the total charge

           Q_total = q₁ + q₂

           Q_total = -2 -4

   

          Q_total = -6 units

it is distributed in between the two spheres evenly since the charges of the same sign repel each other.

When the spheres separate each one has

            q₁ = -6/2

            q1 = q₂=  -3

therefore each sphere has the same charge of -3 untis

What are light years actually? answer in brief
a_sh-v [17]
A light year is a distance. 
It's the distance that light travels in a year, through vacuum.
The distance is about 5.875 trillion miles. 
The nearest star outside our solar system is about 4.2 light years from us.

Sorry to have rambled on for so long.

What mean by expansion effect of heat<br>​
pishuonlain [190]

Answer:

Explanation:

-Cambio de temperatura

Al calentar un cuerpo la temperatura aumenta

Es el efecto más inmediato del calor, el aumento de la temperatura. Al calentar un cuerpo, es habitual, aunque no siempre, que el cuerpo aumente de temperatura. El aumento dependerá de la cantidad de calor que se suministra, del tipo de sustancia y de su cantidad.

-Dilatación

Cuando un objeto se calienta, su volumen aumenta. Este fenómeno se llama dilatación térmica. Por el contrario, cuando un objeto se enfría, su volumen disminuye, debido a la contracción térmica.

Cuando se calienta un cuerpo, además de cambiar de estado o variar su temperatura, también cambia su tamaño, se dilata.

Por ejemplo, los puentes no se construyen de una única pieza, sino que suelen presentar uno o varios cortes longitudinales, las llamadas juntas de dilatación. Si no existieran esas juntas, los cambios de longitud del puente entre el invierno y el verano o entre el día y la noche acabarían por romperlo.

La dilatación de un cuerpo dependerá del aumento de temperatura que experimente, de su tamaño y de la sustancia de que esté hecho. Cuanto más aumente la temperatura más aumentará su tamaño, lo mismo que cuanto mayor sea, mayor se hará.

Todos los cuerpos, ya sean sólidos, líquidos o gaseosos, varían su tamaño cuando intercambian calor con otro cuerpo.

-Cambios de estado:

Si una sustancia modifica el estado de sólido, líquido o gaseoso, se produce un cambio de estado. Un cambio de estado es una modificación en la forma en que se disponen las partículas que constituyen una sustancia.

El estado en que se encuentre un cuerpo depende de la presión a la que está sometido y de su temperatura. Para cambiar su estado se debe modificar alguna de estas variables, o ambas. Al elevar la temperatura de una sustancia sólida, aumenta la agitación de sus partículas.
