The answer is d. Each of its particles becomes surrounded by water molecules.
Notice that when you dissolve a solid compound in the water, it is no longer visible in or eyes, it mixes in the water, it is because it is being divided into smaller particles and each particles were surrounded by the water molecules.
That creates a secondary color
Answer:
Explanation:
a ) The angle required = angle of repose = θ
Tanθ = .81
θ = 39⁰
b ) when angle of incline θ = 44
Net force on the block = mg sinθ - μ mg cosθ where μ is coefficient of kinetic friction
acceleration = gsinθ - μ g cosθ
= 9.8 ( sin44 - μ cos44 )
= 9.8 ( .695 - .69 x .72 )
= 9.8 ( .695 - .497 )
= 1.94 m /s²
I'm guessing that the purpose of the article is to inform the
general public of the work that these Physicists did when they
attempted to detect the existence or non-existence of telepathy
in a controlled, scientifically acceptable setting.
The REASON the article was ever presented in a non-professional
publication was most likely in deference to the general public's interest

weird garbage. In other words, its publication was motivated more by
the desire to sell magazines than by any inclination to impart any real,
useful information to the general public.
