would air resistance being neglected affect the results in anway?

Homework Statement a) What are the factors that contribute to the error in the measurement of the wavelength of laser light? b) Are there methods you might use to reduce the error, given that the wavelength of the laser light is known to at at least four significant digits? The Attempt...

Homework Statement Calculate the end point pH when 50 mL 0.2 mol/L HCl solution reacts exactly with 50 mL 0.2 mol/L NH3 (equivalent to NH4OH) solution. NH3 Kb=1.8x10^-5 The Attempt at a Solution I have no idea how to even attempt this question. Can someone please help me? Thanks.

what if the air table was slanted? how would this affect the collision of the two air pucks?

I think it was done on an air table rather than a regular table because this would cause less friction to occur. If there was more friction, then more kinetic energy and momentum is lost.

This was an actual experiment. Two air pucks were placed on an air table. Airpuck one starts moving and airpuck two is stationary. Soon airpuck one collides with airpuck two. Dots were made on a piece of paper to observe the acutal movement and track of the two pucks. And from this we had to...

The assignment was to observe the collision between two magnetic air pucks and determine the momentums and velocities at various points. This type of collision was elastic, and i had to prove this. So since this collision should be elastic, the total momentum before should equal the total...
