Consider a sound wave traveling from left to right in a certain region in air. If, at a particular time and location, the gauge pressure due to the sound wave is a maximum, what can be said about the displacement of the air molecules at that same time and place

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

More solar radiation is absorbed by earth’s surface than by

If you place a magnet under a clear dish, and sprinkle iron fillings over it, above what part of the magnet will most of the fillings gather
