Answer:

The rain puddle will eventually either evaporate into the air or get absorbed into the ground.

Explanation from the Lesson:

Think about a puddle after a heavy rain. That water is not going anywhere because once the rain has stopped, there is no action. The puddle will not stay there forever; eventually, it will evaporate or sink into the ground .

Answer: A puddle will eventually disappear after a rainstorm ends due to evaporation. This is caused by the heat of the sun, which converts the liquid water into steam (a gas) and evaporates.

Blood pressure is greatly effected by the volume of blood contained in the closed circulatory system of vertebrates. blood volum

Tems11 [23]

The right answer is the kidney will regulate the blood pressure by the renin angiotensin aldosterone system.

The kidney plays a role of selective filtering of the blood. It allows the blood to get rid of its waste. But it also removes water and mineral salts that are in excess.

But the kidney also plays a dynamic role in increasing the pressure, by means of a system called "renin-angiotensin system" which is one of the most powerful natural hypertensives available to the body. Thanks to an enzyme he makes, renin, the kidney will turn a normal blood protein, angiotensinogen, into angiotensin, which causes the vessels in the body to contract and therefore increase blood pressure. This effect is manifested permanently in a disease which is the stenosis of the renal artery, that is to say the permanent narrowing of the caliber of this artery. The kidney, believing that the blood pressure decreases because of this narrowing, will permanently produce renin, which will cause an immediate increase in blood pressure.

Boats are able to stay afloat because of the force caused by...

Ugo [173]

Answer:

d) buoyancy

Explanation:

Buoyancy can be defined as an upward force which is created by the water displaced by an object.

According to Archimede's principle, it is directly proportional to the amount (weight) of water that is being displaced by an object.

Thus, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.

The buoyancy of an object is given by the formula;

$Fb = pgV$

$But, \; V = Ah$

$Hence, \; Fb = pgAh$

Where;

Fb = buoyant force of a liquid acting on an object.

g = acceleration due to gravity.

p = density of the liquid.

v = volume of the liquid displaced.

h = height of liquid (water) displaced by an object.

A = surface area of the floating object.

The unit of measurement for buoyancy is Newton (N).

Additionally, the density of a fluid is directly proportional to the buoyant force acting on it i.e as the density of a liquid decreases, buoyancy decreases and vice-versa.

Boats are able to stay afloat because of the force caused by buoyancy. This simply means that, a boat is able to float because the volume of water it displaces weigh more than its own weight. Thus, if a boat or any physical object weighs more than the volume of water it displaces, it would sink; otherwise, it floats.
