math (perimeter)
i need to find the perimeter of a triangle with the demensions : 2(q^2-3q) , q+10 , and q^2 .
physics
A particle travels horizontally between two parallel walls separated by 18.4m. It moves towards the opposing wall at a constant rate of 7.2m/s. Also, it has an acceleration in the direction parallel to the walls of 2 m/s^2. a) What will its speed be when it hits the wall? b) A...

1) What's the linear velocity of a point on the tip of a 6-ft propeller turning at 1200 revolutions per min? 2) A gear is driven by a chain that travels 90m/min. Find the radius of the gear if it makes 50 revolutions per minute.
math(trig)
1) A 6-ft propeller turns at 1200 revolutions per minute. Compare the angular velocity of the tip with the angular velocity at a point 10 in. from its center. 2) What is the angular velocity of a point on the tread of a 15-in. diameter tire on a car traveling 55 mph?
Chemistry Cell notations
also shouldn't it be the coefficient of H^+ in the second equation be 14?
Chemistry Cell notations
Okay so the problem I had with this is like...I did't understand that when it was written say on the left of the double vertical line how you know H2O --> O2 + H+ will it always be written in the order of how you write the reaction? or like could you also right it like ...
Chemistry Cell notations
Enter the balanced chemical equation including states that describes the electrochemical cell that is represented by the cell notation as shown. Pt(s) l H2O(l) l O2(g) l H+(aq) ll H+(aq), Cr2O72-(aq), Cr3+(aq) l Pt(s)
