Answer:

Options (4) and (5)

Explanation:

The deep oceanic trench is an important geological feature that is formed in a convergent plate boundary. It is a V-shaped depression that forms due to the subducting of the denser plate below the less dense one. As the heavier plate goes down it starts melting, and the melt mixes with the uprising magma. This is how the crustal hard rocks change into hot and molten rocks. These magmas then rise upward forming convection currents. This convergent boundaries forming deep oceanic trenches are responsible for the generation of deep-focus earthquakes.

Thus, the correct answers are options (4) and (5).

The earth orbits the sun once per year at the distance of 1.50 x 1011 m. Venus orbits the sun at a distance of 1.08 x 1011 m. Th

worty [1.4K]

Answer:

Venus will take 223.015 days to make one orbit around the sun .

Explanation:

Given that,

Distance $r = 1.50\times10^{11}\ m$

Distance $r'=1.08\times10^{11}\ m$

We need to calculate the time period for Venus

Using Kepler's third law

For Earth,

$T^2\propto r^3$ ....(I)

For Venus,

$T'^2\propto r'^3$ ....(II)

Ratio of equation (I) and (II)

$\dfrac{T'^2}{T^2}=\dfrac{r'^3}{r^3}$ ....(I)

Put the value in the equation

$\dfrac{T'^2}{T^2}= \dfrac{1.08\times10^{11}}{1.50\times10^{11}}$

$T'^2=\dfrac{1.08\times10^{11}}{1.50\times10^{11}}\timesT^2$

$T'^2=(\dfrac{1.08\times10^{11}}{1.50\times10^{11}})^{\dfrac{3}{2}}\times1$

$T=0.6109\ earth year$

$T=0.611\times365$

$T=223.015\ days$

Hence, Venus will take 223.015 days to make one orbit around the sun
