In which region of the Sun does energy move as waves that transfer from atom to atom? photosphere corona core radiative zone chr

Tatiana [17]

Answer : Option B) Radiative zone

Explanation : The sun consists of many zones in it. Particularly in the radiative zone, the energy is primarily transported toward the exterior side by the process of radiative diffusion and thermal conduction, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as photons and energy is transformed from atom to atom.

Find the ratio of the lengths of the two mathematical pendulums, if the ratio of periods is 1.5

juin [17]

Answer:

The ratio of lengths of the two mathematical pendulums is 9:4.

Explanation:

It is given that,

The ratio of periods of two pendulums is 1.5

Let the lengths be L₁ and L₂.

The time period of a simple pendulum is given by :

$T=2\pi \sqrt{\dfrac{l}{g}}$

$T^2=4\pi^2\dfrac{l}{g}\\\\l=\dfrac{T^2g}{4\pi^2}$

Where

l is length of the pendulum

$l\propto T^2$

$\dfrac{l_1}{l_2}=(\dfrac{T_1}{T_2})^2$ ....(1)

ATQ,

$\dfrac{T_1}{T_2}=1.5$

Put in equation (1)

$\dfrac{l_1}{l_2}=(1.5)^2\\\\=\dfrac{9}{4}$

So, the ratio of lengths of the two mathematical pendulums is 9:4.

Which rational number could be graphed between 0 and 1?A number line going from negative 5 to positive 3 in increments of 1.Nega

vovikov84 [41]

In order to find which rational number is between 0 and 1, let's convert them into their decimal form:

$\begin{gathered} \text{negative one-half:} \\ -\frac{1}{2}=-0.5 \\ \\ \text{one}-\text{fourth:} \\ \frac{1}{4}=0.25 \\ \\ \text{three}-\text{halves:} \\ 3\cdot\frac{1}{2}=\frac{3}{2}=1.5 \\ \\ 1.75 \end{gathered}$

Looking at the numbers in their decimal form, we can see that the number between 0 and 1 is one-fourth, therefore the correct option is the second one.
