The smallest functional and structural unit of an organism, usually microscopic and consisting of cytoplasm and a nucleus in a membrane.
pH = - log[acid] = -log [H+]
pH= -log[10] = 1
Thus, pH is 1
if pH is 7, the solution is neutral and if pH is greater than 7 the solution is basic and if it is less than 7 the solution is acidic.
This solution have pH = 1, thus the solution is acidic.
The answer is -30 N
The explanation:
- to make the box move. so,the horizontal force must be greater than the frictional force.
-and when the horizontal force applied is 30 N. So, the box will remain stationary if the frictional force is equal in magnitude but opposite in direction to the horizontal force. means frictional force = -30 N
This is also being indicate that vertical force due to gravity is equivalent to the normal force when gravity force = 8 N and normal force =8 , meaning the box does not move vertically.
