Aaron, from question 1. turns to walk back to the house. Halfway up the driveway he gets
a text and stops to check his phone. From
the front door to his current position, what is
Aaron's displacement? Distance traveled?

Two red blood cells each have a mass of 9.0 multiply.gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries −2.50 pc of charge and the other −3.10 pc, and each cell can be modeled as a sphere 7.5 μm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer

Ascrew incorporates which other simple machine? lever wheel and axle inclined plane pulley

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.
