Formula for gravitational force shows it is inversely proportional to the distance between two masses squared this is similar to the electrostatic force thay changes according to the separation squared.
The difference is that gravity is proportional to the product of the two masses. Electro static force is proportional to the product of the two charges.
Sound travels fastest through matter in the <em>solid state</em>.
I know this from having answered a huge number of Brainly questions that required me to look up things like this:
-- Speed of sound in air . . . about 340 m/s
-- Speed of sound in sea-water . . . about 1,500 m/s
-- Speed of sound in steel . . . about 5,960 m/s
A heliocentric system is a sun-centered
Answer:
option D
Explanation:
given,
wavelength = 600 nm
width of separation = 0.02 mm
L = 5 m
for mth order maxima
for (m+1)th order maxima
now,
and
hence,
hence, the correct answer is option D
