I'm doing a science experiment where I'm suppose to figure out if more weight increases velocity. My first question is-is velocity the same the same thing as speed? Second question-If the formula for velocity is V=Vo+at how would i measure acceleration and what is initial velocity? EX.-So, if a rolled a skateboard down a hill and it was going 5mph would that be my initial velocity,initial velocity or or acceleration?

Could you PLEASE explain WHY a graph passes *through* the x-axis when the root/factor is of an odd multiplicity, and why a graph *bounces off* the x-axis when it's an even multiplicity?
WHY is the keyword. please please explain why!
and please no junk/useless answers either. please only answer if you know what you're talking about!
(sorry for using all these caps, but i'm a little desperate,,,)

(HN3) (3=subscript)is a low boiling point liquid that is soluble in water in small quantities. It partially dissociates to form hydronium ions and azide ion (N3-)(3=subscript), with the pKa of 1.9 x 10-5 (5=subscript).

Calculate the pH of a solution of 0.724 g of HN3 in 400mL of water. Ignore any increase in volume due to small amount of HN3.

show work please.

It's for my math homework. I'm not trying to cheat. I have the answer on the "tip of my tounge", but just can't put it in words. Would it be because -1 is well, negative, so it's reciprocal has to be negative?

can anyone help me do this?
A child on a merry-go-round is moving with a speed of 1.05 m/s when 1.20 m from the center of the merry-go-round.
(a) Calculate the centripetal acceleration of the child.
m/s2 = --Direction-- toward the center away from the center tangent to the circular path
(b) Calculate the net horizontal force exerted on the child (mass = 25.0 kg).
N --Direction-- toward the center away from the center tangent to the circular path
