adjust the mass of the skater to 15kg . what is their kinetic and potential energies at the bottom of the ramp? their kinetic and potential energies at the top of the Ramp?​

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

What organization and environment is described above?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
