Acid & base mix & become neutral which cures the acidity

Explanation

Earth science is the study of the Earth's structure, properties, processes, and four and a half billion years of biotic evolution.

Understanding these phenomena is essential to the maintenance of life on the planet.

Geoscience also called Earth Science

Explanation

Pressure:

The speed of sound is independent of pressure

i.e. speed remains unchanged by the increase or decrease of pressure. 

Temperature:

The speed of sound is directly proportional to the temperature.

Therefore, as the temperature increases, the speed of sound increases.

Humidity:

The speed of the sound increases in humid air compared to the dry air

Because of the weight of water vapor

Explanation

Weight(mg) of a block = 20N

Height (h) = 6m

Now, potential energy(PE) = mgh

=20 × 6

= 120Joules

The potential energy stored in it is 120 joules.
