Answer:
Base
Explanation:
anything with a pH between 0-6 is an acid. pH of 7 means neutral. 8-14 means it is a base
hope I helped :)
I will assume here that the well is sufficiently short so that the time the sound takes to come from the bottom of the well to our ear is negligible.
Since the pebble moves by uniformly accelerated motion, the distance it covers is given by

where

is the gravitational acceleration

is the time the pebble takes to reach the bottom of the well
Therefore, the depth of the well is

and the correct answer is B.
The correct option is D.
Because <span>the distance that the honey flows is a dependent variable. Becuase the coefficient of viscosity is dependent on the velocity gradient (v/L). And, </span>Viscosity is very temperature dependent • It decreases with increasing temperature (in case of liquids). But, Viscosity of a gas increases with increasing temperature.
