Question

Answer my questions on the above attachment. I will mark you as brainliest answer​

Answer 1

Answer:

Explanation:

1 When the rod is heated the distacne between any adjacent molecules increases hence the perimeter of rectangle and the gap between P and Q increases

2 The pressure inside a liquid at the same depth will be equal. But the liquid pressure differs with the height of the liquid. The pressure of the liquid at a depth is proportional to the depth.(P∝h)  

Pressure at A< Pressure at B< Pressure at C

3  W = V×Q

W = I×R×Q

4000 = I ×50×10

I = 4000 /50×10

I = 8 A
