Answer:
the wind carries abrasive materials
Explanation:
such as sand and salt over time theses small particles slowly strip way at the land form sculpting it by eroding the softer layers first
I think the answer is Snow flakes
When your head sticks out of the water the upthrust reduces as your head is no longer displacing water, and there is 0 resultant force so you float at that level. hope this helps, can i get brainliest please
Answer:
The fraction of the maximum intensity a distance y 5 0.600 cm away from the central maximum is 0.97.
Explanation:
d = 0.180 mm = 1.8 x 10⁻⁴ m
L = 80 cm = 0.8 m
λ = 656.3 nm = 6.563 x 10⁻⁷ m
y = 0.6 cm = 6 x 10⁻³ m
we know that the equation of the intensity for two slits interference equation is
I =
cos²(πdy/λL)
where
I = intensity
= maximum intensity
d = distance of two slits
y = the distance of the interference with the central
L = the distance of screen and the slits
λ = wavelength
so,
I =
cos²(πdy/λL)
I/
= cos²(πdy/λL)
= cos²[π (1.8 x 10⁻⁴) (6 x 10⁻³)/(6.563 x 10⁻⁷) (0.8 )]
= 0.97
