**THIS IS THE ANSWER**Geologists determine absolute age by comparing the amounts of radioactive and nonradioactive elements in *IGNEOUS rock. The radioactive, or *UNSTABLE
elements decay into nonradioactive elements. Because this
rate of decay is *CONSTANT
for each element, geologists can compare the amounts of stable and unstable elements
to determine how much of the *STABLE
elements have formed over time.

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 β2.50 pc of charge and the other β3.10 pc, and each cell can be modeled as a sphere 7.5 ΞΌm 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

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
