In an electromagnetic wave, the electric and magnetic fields are oriented such that they are
 
  A) parallel to one another and perpendicular to the direction of wave propagation.
  B) parallel to one another and parallel to the direction of wave propagation.
  C) perpendicular to one another and perpendicular to the direction of wave propagation.
  D) perpendicular to one another and parallel to the direction of wave propagation.

Question 2

An LC circuit consists of a 3.4-F capacitor and a coil with a self-inductance 0.080 H and no appreciable resistance. At t = 0 the capacitor has a charge of 5.4 C and the current in the inductor is zero.
 
  (a) How long after t = 0 will the current in the circuit be maximum?
  (b) What will be this maximum current?
  What will be an ideal response?

Adults are resistant to the bacterium that causes Botulism. These bacteria thrive in honey – therefore, honey should never be given to infants since their immune systems are not yet resistant.

Did you know?

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum. About 10% of Americans older than age 40 years have diverticulosis, which, when the pouches become infected or inflamed, is called diverticulitis. The main cause of diverticular disease is a low-fiber diet.
