Answer:

Explanation:

At a convergent boundary, the denser plate – usually the oceanic plate, is subducted under the less dense plate- usually the continental plate. Due to stress of the subduction, the two plates press against each other as they collide and begin to bend forming a deep trench at the boundary. At the boundary, as the subducted plate dives into the mantle it melts and the magma rises and erupts through the fissures within the boundary forming mountain ranges. Whenever there are mountains there are valleys too.

The spectrum of a blackbody has a peak wavelength of 2.80×10-7 meters. What is its temperature, in kelvins?

-BARSIC- [3]

Answer: $1.03\times 10^4K$

Explanation:

Using Weins displacement law:

$\lambda _{max}=\frac{b}{T}$

where $\lambda _{max}$ = wavelength = $2.80\times 10^{-7}m$

b = constant = $2.897\times 10^{-3}mK$

T = Temperature in Kelvin = ?

Putting the values we get:

$2.80\times 10^{-7}m=\frac{2.897\times 10^{-3}mK}{T}$

$T=1.03\times 10^4K$

Thus the temperature of the blackbody will be $1.03\times 10^4K$

weeeeeb [17]

Answer:

Option (C)

Explanation:

Migmatite can be defined as metamorphic rock that is formed at high pressure and temperature condition, depicting pro-grade type of metamorphism. This rock is formed from the partial melting of unaltered minerals or those minerals that are slightly modified. But in this process of formation, the bulk mass of the rock remains consistent. It is a transitional rock between the igneous and the metamorphic rock.

Thus, the correct answer is option (C).
