Answer:
Sedimentary rocks are usually formed under water when grains of broken rocks are glued together while igneous rocks form when melted rock (magma or lava) cools and metamorphic are rocks that once were igneous or sedimentary rocks but have been changed by pressure and temperature.
Answer:2155 J
Explanation:
Given
Change in Internal energy 
i.e. decrease in Internal Energy
Heat added to system 
According First law for a system
Thus 2155 J of work is done by system
B.---A. warm water B. thermocline C. cold water
Answer:
Option A and B
Explanation:
In the parallel connection, the capacitors that are connected in parallel have the same potential difference across each capacitor as the battery. Therefore, statement A is correct.
Charge (Q), capacitance (C) and voltage across capacitor (V) is related with each other as follows:
Q = C ×V
As capacitance is not same for all the capacitors, therefore each capacitor carries different charge. Therefore, statement C is incorrect.
As potential difference across each capacitor is same, therefore, capacitor with the largest capacitance carry the most charge. Therefore, statement B is correct.
Therefore, statements A and B are correct.
Answer:
Distance, d = 8 meters
Explanation:
Given that,
Initial velocity of the motorboat, u = 7 m/s (west)
Final velocity of the motorboat, v = 2.4 m/s (west)
Acceleration of the motorboat, 
(east)
We need to find the distance covered by it. It can be calculated as :
s = 8 meters
So, the distance covered by the motor boat is 8 meters. Hence, this is the required solution.
