In 1962, measurements of the magnetic field of a large tornado weremade at the Geophysical Observatory in Tulsa, Oklahoma. If themagnitude of the tornado's field was B = 16.50 nT pointing north when the tornado was8.10 km east of the observatory, whatcurrent was carried up or down the funnel of the tornado?

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
