25.4 and 25.5 Frequency, wavelength, and the electromagnetic spectrum and Mathematical description of EM waves and EM wave energy

20 * The electric field in a sinusoidal wave changes as

E = ( 25  N/C) cos [( 1 .2 × 10 11  rad/s ) t + ( 4.2 × 10 2  rad/m ) x ]

(a) In what direction does the wave propagate? (b) What is the amplitude of the electric field oscillations? (c) What is the amplitude of the magnetic field oscillations? (d) What is the frequency of the wave? (e) What is the wavelength? (f) What is the speed? (g) What other information can you infer from the equation?

! Required information Two chloride ions and two sodium ions are in water, the "effective charge" on the chloride ions (CI¯) is −2.00 × 10-21 C and that of the sodium ions (Na+) is +2.00 x 10-21 C. (The effective charge is a way to account for the partial shielding due to nearby water molecules.) Assume that all four ions are coplanar. CT Na+ Na+ 30.0° 45.0% с сг L. where a = 0.300 nm, b = 0.710 nm, and c = 0.620 nm. What is the direction of electric force on the chloride ion in the lower right-hand corner in the diagram? Enter the angle in degrees where positive indicates above the negative x-axis and negative indicates below the positive x-axis.

Part A ■Review The uniform 150-lb stone (rectangular block) is being turned over on its side by pulling the vertical cable slowly upward until the stone begins to tip. (Figure 1) If it then falls freely (T = 0) from an essentially balanced at-rest position, determine the speed at which the corner A strikes the pad at B. The stone does not slip at its corner C as it falls. Suppose that height of the stone is L = 1.2 ft.
