Answer:
The Lambda-CDM model contains a cosmological constant, denoted by a lambda (λ), which is associated with dark energy and <u>cold dark matter</u>.
^Also works for Plato users.
The superposition principle is responsible for alternating light and dark bands when light passes through two or more narrow slits.
The intensity pattern that appears on the lit screen is determined by the superposition principle. When the difference in pathways from the two slits to a location on the screen equals an integral number of wavelengths (0,λ,2λ ,...), constructive interference takes place.
The fact that the two waves' crests follow different paths ensures that they do. A distinctive pattern of brilliant and dark fringes is seen when monochromatic light illuminates a distant screen after passing through two small openings. The superposition of overlapping light waves coming from the two slits results in this interference pattern.

Explanation:
Density is measured in kg⋅m−2 . This means that it is derived from fundamental units which are the kilogram and metre.
Answer:
the correct answer is option A
Explanation:
given,
Load = 6000 lbf
depth = 3.5 ft
distance from the load = 4 ft
vertical stress = 
= 
= 28.96 lbf/ft²
= 29 lbf/ft²
hence, the correct answer is option A
