☆☆☆☆☆The dnsity of a submerged submarine is the same as the density of the water if the density of the submarine was grater it will sink, if the density was less it would float.
The magnitude of the balls displacement is 9 meters.
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
It produces hydroxide ions - Jon
It has variable acceleration
Isaac Newton defines force as mass times acceleration.
There is little mass to the bug compared to an automobile.
the earth and moon have different values for the acceleration due to gravity.
[H3O+] = 1x10^-7 M = hydronium ion concentration
[OH-] = 1x10^-7 M = hydroxide ion concnetration
