Two continuous waves having the same wavelength and amplitude pass through the same medium. They are aligned crest to crest and trough to trough so that they interfere. The resulting wave has
A) the same wavelength and the same amplitude.
B) twice the wavelength and twice the amplitude.
C) zero amplitude.
D) twice the wavelength and the same amplitude (or height) as each of the individual waves.
E) the same wavelength and twice the amplitude.
Question 2
During World War I, Germany used a Big Bertha cannon to hurl shells into Paris 30 miles away. This gun also had a very long barrel. What was the reason for using a long barrel in these guns?
A) to increase the force exerted on the bullet due to the expanding gases from the gunpowder
B) to reduce the force exerted on the bullet due to the expanding gases from the gunpowder
C) to reduce frictional losses
D) to exert a larger force on the shells
E) to allow the force of the expanding gases from the gunpowder to act for a longer time
