<span>If two objects collide, each object exerts a force equal to and in the opposite direction of the other.</span>
Answer:
A) 3.11 Hrs
Explanation:
Wave speed is given by the formula

now we will have


now the time taken by the wave to move the distance 560 km is given as



t = 3.11 hours
The wind speed increased but in the same direction.
It is A/1 because the wind speed did increase and it is still going the same way clockwise because it also did not move that much.
When copper carbonate is heated, it decomposes to form a black residue. This black residue is actually copper(II) oxide. Along with this black residue, carbon-dioxide is released. The complete reaction is the following:

The law of conservation of mass holds true. 123.6 g of copper carbonate decomposes to 79.6 g of copper oxide and (123.6 g-79.6 g=44 g) 44 g of carbon-dioxide.
