Answer:
Explanation:
The weight of the Earth = 
0.1% of the weight of the Earth will be
As per a research conducted in 2014, it was estimated that 60 tons of cosmic dust fall on the Earth every day. So, the time it would take for the cosmic dust to make up 0.1% of the weight of the Earth will be,
.
Though the quantity of the cosmic dust might seem huge but its negligible in comparison to the weight of the Earth. Also, this cosmic dust plays a role in formation of clouds and fertilization of plankton in Polar region.

Answer:
The velocity at impact is 222.2 m/s
Explanation:
The given information are;
The time at which the woman heard the sound of the coin after dropping it into the wishing well = 30 seconds
The average speed of sound in air = 344 m/s
The time in which the dime travel = t₁
The time in which the sound travel = t₂
1/2 × 9.8 × t₁² = 344 × t₂
t₁ + t₂ = 30
4.9·t₁² = 344 × (30 - t₁)
4.9·t₁² + 344·t₁ - 10320 = 0
Which gives -344±
t₁ = 22.676 seconds or -92.9 seconds
Therefore the correct natural time is t₁ = 22.676 seconds
The velocity at impact, v = g×t₁ = 9.8 × 22.676 = 222.2 m/s
The velocity at impact= 222.2 m/s.
