Answer 1

Answer:

B

Explanation:

Until brakes were applied the water tanker was kept on moving which means water was also in motion. But when brakes are applied, the tank will stop but the water will always try to move in the previous direction due to the property of inertia. Hence water will move forward when brakes are applied.

Answer:

(C) Rise upward
