How many electrons can the first shell hold

The energy flow to the earth from sunlight is about 1.40 kw/m2. part a find the maximum value of the electric field for a sinusoidal wave of this intensity.

As a longitudinal wave moves through a medium, the particles of the medium (1) vibrate parallel to the direction of the wave's propagation (2) vibrate perpendicular to the direction of the wave's propagation (3) are transferred in the direction of
