Astudent is conducting an experiment to determine how cold temperatures affect the growth of tadpoles in a tank of water. which instrument would give the most accurate measurement of water temperature? a calibrated bulb thermometer that has a readout from 15 c to 25 c a calibrated digital thermometer that has a readout from 50 c to 250 c an uncalibrated bulb thermometer that has a readout from 0 c to 100 c an uncalibrated digital thermometer that has a readout from 10 c to 100 c

Bone-strengthening physical activity done increases bone-mineral content and bone density in youth.

What you see with your eyes is a form of energy. a. light b. heat c. chemical d. electrical

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
