Question

Please help with 12. And 13.

Answer 1

12. the air in the tank will expand because of the heat in the car. Since the air is under very high pressure, the tank will explode

13. following Pascal's principle,press pressure exerted on one part of a compressed fluid will be exerted equally on all other parts of the fluid. therefore;

2500 ÷ 25 = x ÷ 5

100 = x ÷ 5

100 × 5 = x

x = 500N

Answer 2

12. it should not be left in a hot car because it could explode when the pressure gets to high (this is why i assume)
