(Ill) An inclined plane, fixed to the inside of an elevator,makes a 32 angle with the floor. A mass m slides on theplane without friction. What is its acceleration relative tothe plane if the elevator (a) accelerates upward at 0.50 g,(b) accelerates downward at 0.50 g, (c) falls freely, and(

• pH and Acid/Base Balance • What is pH – Can be thought of as the power of Hydrogen concentration in a solution – Mathematical definition- negative logarithmic value of the hydrogen ion (H+) concentration, or • pH = -log [H+] – Negative Logarithm- a negative scale based on ten • As the hydrogen ion concentration goes up, the scale goes down • Example: 1 is ten times more that 2 » 3 is a hundred time less than 1 (10 x 10 = 100) • What is the pH for an Acid Neutral A base • pH of Common Products • Physiological pH • Normal body pH is between 7.35-7.45 or ~ 7.4 • So,
