Answer:
Explanation:
As we know that position of maximum on the screen in diffraction pattern is given as
here we know that
position of third maximum due to red color light and position of fifth maximum of unknown wavelength are same
so we have
so we have
Advances in space travel will help astronomers discover new parts of the solar system, thus add to their knowledge.
Answer:
Explanation:
As we know that the resultant of two vectors is given as
here we know that
now we have
the answer is waning Gibbous
The Waning Gibbous is an intermediary Moon phase. It starts right after the Full Moon, and it lasts until the Third Quarter.
Explanation:
Given parameters:
Frequency = 500Hz
Unknown:
a. Period of rotation
b. Time required to complete 7 rotation
Solution:
The period of rotation is the time taken to complete a turn.
P =
P is the period
t is the time
n is the number of turns
Period is the inverse of frequency;
P = = 0.002s
b.
Time required to complete 7 rotation;
P =
t = P x n
t is the time
P is the period
n is the number of rotations
t = 0.002 x 7 = 0.014s
