A student placed three identical plant seedlings in soil in three identical containers and gave each seedling a different amount of water each day. The student measured the height of each seedling every day for four days. 1. Identify the dependent (responding) variable in this experiment.

2. Describe the general relationship between the amount of water each seedling received and it’s height on day 4.

3. The plant seedlings and containers were identical. Identify one additional factor that should be held constant in this experiment.

What is the momentum of a 2 kg object moving at 15 meters per second

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field. it is in the opposite direction from that of the original external field. it has a direction determined entirely by the charge on its surface. it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0

Acapacitor is storing energy of 3 joules with a voltage of 50 volts across its terminals. a second identical capacitor of the same value is storing energy of 1 joule. what is the voltage across the terminals of the second capacitor?
