Question

Which probing question lies within the scope of physics? A. Are fish in the open ocean attracted by underwater sounds? B. Does increasing the saltiness of ocean water affect the speed of sound in the water? C. What effect does the release of industrial wastewater have on the acidity of oceans? D. What is the effect of rising sea temperatures on ocean currents?

Answer 1

Question A, B, D belongs to scope of physics such as in question A sound under the water travels in form of current and thus these currents are quite lower in deep water where the aquatic animal find stability in comparison to shallow water or near to the water surface where the current is higher.

In question B, speed of sound under the water can be caliberated by the concentration of the ions present in the water and thus higher the concentration greater will the speed of sound.

In C, the current of ocean is higher in summer due to the higher temperature and thus Question A, B, D belongs to scope of physics only C belongs to chemistry asking about the mixing of wastewater in river to increase acidity all relates to pH of water.
