If a solid piece of naphthalene is heated and remains at 80c until it is completely melted , you know that 80c is the .?

Two positive charges are equal. which has more electric potential energy?

The earth's magnetic field, with a magnetic dipole moment of 8.0×1022am2, is generated by currents within the molten iron of the earth's outer core. suppose we model the core current as a 3000-km-diameter current loop made from a 1000-km-diameter “wire.” the loop diameter is measured from the centers of this very fat wire.to decide whether this is a large or a small current density, compare it to the current density of a 7.0 a current in a 2.0-mm-diameter wire.

Which correctly identifies the parts of a transverse wave? a: crest b: amplitude c: wavelength d: trough a: trough b: amplitude c: crest d: wavelength a: trough b: amplitude c: wavelength d: crest a: crest b: amplitude c: trough d: wavelength
