# Amass of 30.0 grams hangs at rest from the lower end of a long vertical spring. you add different amounts of additional mass δm to the end of the spring and measure the increase in length δl of the spring due to the additional mass. you plot your data in the form δl (vertical axis) versus δm (horizontal axis). plotted this way, your data lies very close to a straight line that has slope 0.0364 m/kg. what is the force constant k of the spring? use g = 9.80 m/s2.   ### Other questions on the subject: Physics Physics, 22.06.2019 02:00, nhjkhfh
Aclass is designing an experiment about duckweed growing conditions. the hypothesis for the duckweed experiment is, “if duckweed is grown at ph 5, then it will grow at the same rate as when grown at ph 7, or normal ph, because it can tolerate mildly acidic environments.” identify the control group in this experiment.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
