A group of biology students tests the growth of bacteria under different conditions. The students apply the same amount of bacteria to identical
Petri dishes enriched with nutrients, then place
which the number of bacterial colonies
each plate at a different temperature. The
on
bacteria are allowed to
grow for three days, after
each plate is counted. What is the dependent variable in this experimenA

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?

Aball is thrown upward in the air, and its height above the ground after t seconds is h ( t ) = 57 t − 16 t 2 feet. find the time t when the ball will be traveling upward at 14.25 feet per second.

Which articulations allow for greatest range of motion?
