Intense temperature and pressure of regional metamorphism
Explanation:
The process that cause the formation of the Vishnu Schist is the intense temperature and pressure as a result of regional metamorphism.
- Regional metamorphism is an extensive metamorphism of an area as a result of temperature and pressure changes.
- The schist is a foliated metamorphic rock usually found in areas of moderate to high grade temperature and pressure.
- The Vishnu schist must have been metamorphosed before the new sediments were deposited on top.

I believe the answer is D. The milky way is a spiral galaxy, You can tell just by looking at it.

v = 56 x 100/60 x 2 pi
v = 56x5/3x6

<u>Answer:</u>
<em>The initial distance between the trains is 1450 m.
</em>
<u>Explanation:</u>
In the question two trains are of equal length 400 m and moves at a uniform speed of 72 km/h. train A is moving ahead of train B. If the train B has to overtake train A it should accelerate.
Train B’s acceleration is
and it accelerated for 50 seconds.
<em>
</em>
<em>t=50 s
</em>
<em>initial speed u=72km/h
</em>
<em>we have to convert this speed into m/s </em>
<em>
</em>
<em>Distance covered in accelerating phase
</em>
<em>
</em>
<em>
</em>
If a train is just behind another, the distance covered by the train located behind during overtaking phase will be equal to the sum of the lengths of the trains.
<em>Here length of train A+length of train
</em>
<em>Hence the initial distance between the trains =
</em>
1/2 x 240 x 64 = 120 X 64 = 7680 J
