Here are the data obtained by one pair of students when they performed the experiment on the density of a gas: Mass of test tube, water, and tablet before the reaction 35.00 g
Mass of test tube and contents after the reaction 34.22 g
Volume of gas collected 411 cm3

Which method should the students use to calculate the density of the gas in g/cm3?

A. 35.00
411

B. 34.22
411

C. 411
35.00

D. 411
35.00-34.22

E. 35.00-34.22
411

Animals respond in various ways to stimuli detected through their senses. some of these responses are stimulated by the presence of danger. which of these animal responses is the best example of a response to an immediate threat? a) a rooster crows every morning at the first sign of light. b) as something approaches an octopus, it shoots a cloud of ink. c) from late fall until spring, bears hibernate to preserve energy. reactivate d) a dog is getting hot in the sunlight, so he moves to a shaded area.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
