An interference experiment has two light beams. one beam travels 5.5 wavelengths and the other beam travels 3.5 wavelengths. when the two beams are combined what happens?

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

double the distance = divide strength by 4

in physics zero. in muscle fatigue could be high
