Answer:
2.5 m/s²
Explanation:
a = ∆v/∆t = (15 m/s)/(6 s) = (15/6) m/s² = 2.5 m/s²
Answer:
2.8512*10^8 inches
Explanation:
Seeing as the ratio for miles to inches is 1 mile = 63360 inches, set up an equation. 1 mile / 63360 inches = 4500 miles / x inches. Cross multiply and simplify to 2.8512*10^8 inches. Hope this helps! :)
Answer:
h = 3600 km
Explanation:
Given,
The mass of the Earth, M = 6 x 10²⁴ km
The radius of the Earth, R = 6.4 x 10³ km
The acceleration of the meteor at height, x = 4 m/s²
The acceleration due to gravity at the surface of the Earth is given by the formula,
g = GM/R²
At height 'h' acceleration is given by the formula,
gₓ = GM/Rₓ²
Rₓ² = GM/gₓ
= 6.673 x 10⁻¹¹ X 6 x 10²⁴ / 4
= 1 x 10¹⁴
Rₓ = 1 x 10⁷ m
Where,
Rₓ = R + x
x = Rₓ - R
= 10000 km - 6400 km
= 3600 km
Hence, the height of the meteor where its acceleration due to gravity is 4 m/s² is, h = 3600 km
Karst topography is created by the chemical weathering process of CARBONATION. Carbonation affects limestone and other carbonate rocks. The action of carbonation creates a distinctive landscape of little surface drainage, sink holes, caves and cockpits.
Rain water mixes with carbon dioxide in the atmosphere to form a weak carbonic acid. The carbonic acid then reacts with the calcium carbonate in the rocks to form a soluble calcium bicarbonate that is easily washed away by water.
Answer:
The width is 
Explanation:
From the question we are told that
The wavelength is 
The width of the slit is 
The distance of the screen is 
Generally the central maximum is mathematically represented as
Here y is the width of the first order maxima which is mathematically represented as
substituting values
So
