Water located in wells underground is
A
run-off.
B
precipitation
с
ground water.
D
condensation.
Answers
Answer:
Aquifers but since there is no answer choice I say groundwater .
Hope this helps .
Water located in wells underground is ground water. Therefore, the correct option is option C.
Water that is found below the earth's surface in cracks in rocks and the crevices between soil particles is known as groundwater. It is essential for maintaining ecosystems on our planet and supporting human activities. Groundwater is created and made available by precipitation and surface water that seeps into the ground. It gathers in subterranean aquifers, which are enormous water reservoirs contained in permeable rocks or sediments. The thickness and depth of these aquifers vary. Groundwater supply is influenced by elements like rainfall, geology, and human use. Groundwater is an important resource since it is necessary for a variety of purposes. It provides over half of the world's population with their main supply of drinking water.
Therefore, the correct option is option C.

The aorta carries blood away from the heart and eventually branches into a large number of capillaries that distribute the blood to various body organs. If for an average person, the aorta has a radius of 1.2 cm and blood travels through it at a speed of 42 cm/s and the capillaries have an average radius of 5.0 10-4 cm and blood travels through them at a speed of 0.005 cm/s, determine the approximate number of capillaries in the human body.
Answers
Answer:
There are approximately 5 × 10¹⁰ capillaries in the human body
Explanation:
The motion of a fluid is such that the mass of the fluid flowing remains constant. This is known as the principle of conservation of mass in liquid flow.
The mass flow rate is the mass that passes a given point per unit time. According to the principle of conservation of mass, the flow rates at any two points must be equal, as long as no fluid is being added or taken away.
The principle gives rise tonthe continuity equation which is given below:
ρ₁A₁v₁ = ρ₂A₂v₂
Where ρ is density of fluid, A is internal area of the vessel or pipe the fluid is flowing through, v is velocity of the fluid
Since the density of blood is constant, the continuity equation above reduces to:
A₁v₁ = nA₂v₂
where A₁ is the area of the aorta, v₁ is velocity of bloodmin the aorta, n is number of capillaries, A₂ area of capillary, v₂ is velocity of blood in the capillary.
n = A₁v₁/A₂v₂
n = πr₁² × v₁ / πr₂² × v₂ where r₁ is radius of aorta and r₂ is radius of capillaries
n = (22/7 × 1.2² × 42) / (22/7 × 0.0005² × 0.005)
n = 4.8384 × 10¹⁰capillaries
Therefore, there are approximately 5 × 10¹⁰ capillaries in the human body

How would adding finer particles to the sand affect porosity?
Answers
Explanation:
Porosity depends on the size, shape, and mixture of grains and particles that compose soil and rock. For instance, small particles such as clays can compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them.
