In terms of pH, explain how a strong acid and water are different.

Water's pH level is usually 6.5-8.5, any lower and it becomes acidic. Strong acid usually has a pH level of 0-1.

Explanation:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
