Students set up a controlled experiment. They put five crickets in each of three identical containers. They set one container to 15C, one to 20C, and another to 25C. Then they count the number of cricket chirps in each container during one hour. What are TWO constants in this experiment?

A:The temperature of each container
B:the number of crickets in each container
C:The kind of containers used
D:The number of cricket chirps.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Consider the following position function. find (a) the velocity and the speed of the object and (b) the acceleration of the object. bold r left parenthesis t right parenthesisr(t)equals=left angle 6 t superscript 4 baseline comma 2 t cubed right angle6t4,2t3 for tgreater than or equals≥0
