I think with the increasing of temperatures of earths oceans and atmosphere is causing climate change and global warming. When the ocean heats up a lot of sea animals die and with the hot temps in the atmosphere is causing rare hot tempatures in some places in the world.
It can cause some intense storms but it mostly heats up the world and cause a lot of problems.

I hope i answered your question right.

Answer:

1)     Pm₂ = 1.9 10⁴ Pa , b)  P_feet = 5.4 10⁴ Pa , c)  Pm₄ = 4.4 10⁴ Pa

Explanation:

a) Pressure can be found using Bernoulli's equation

         P₁ + ½ rho v₁² + rho g y₁ = P₂ + ½ rho v₂² + rgo g y₂

The amount of blood that runs through the constant system, all the blood that reaches the brain leaves it, so we can assume that the speed of entry and exit of the total blood is the same. In this case the equation is

       P₁-P₂ = rgo h (y₂-y₁)

The gauge pressure is

      Pm = P₁ -P₂

      Pm₂ = 1.06 10³ 9.8 1.83

      Pm₂ = 19 10³ Pa

      Pm₂ = 1.9 10⁴ Pa

The pressure in the heart is

      Pm₁ = 246 torr (1,013 10⁵ Pa / 760 torr) = 3,279 10⁴ Pa

Therefore the gauge pressure is an order of magnitude less

Total or absolute pressure is

      Pm₂ = P_heart - P_brain

      P_brain = P_heart - Pm₂

      P brain = 3,279 10⁴ - 1.9 10⁴

      P brain = 1.4 104 Pa

b) on the feet

    Pm₃ = rho g y₃

    y = 2.04 m

    Pm₃ = 1.06 10³ 9.8 2.04

    Pm₃ = 21 10³ Pa

   Pm₃ = 2.1 10⁴ Pa

Total pressure

    Pm₃ = P_feet + P_heart

   P_feet = Pm₃ + P_heart

  P_feet = 3,279 10⁴ + 2.1 10⁴

 P_feet = 5.4 10⁴ Pa

c) If you lower your head the height change is

    h = 1.83 +2.04

    h = 4.23 m

    Pm₄ = 1.06 10³ 9.8 4.23

    Pm₄ = 4.4 10⁴ Pa

In astronomy, Johannes Kepler published his three laws about planetary motion. It is one of the most important things in astronomy. So Kepler gives three laws about planetary motion.

<h3>What is motion?</h3>

Motion is a physical term in physics. If a particle of mass m and affected by some force F then it change its position in many different way. That is the motion of the object. It is a vector quantity.

<h3>What is Kepler's three laws?</h3>

In astronomy, Johannes Kepler published his three laws about planetary motion between 1609 and 1619. This shows about motion describe the orbits of planets around the Sun. So the three motions are shown following,

<u>First law</u>: Every planet in solar system that moves in a elliptical orbits where the sun always in the center of the motion.

<u>Second law</u>: Every planet covers the same amount of distance in a constant time no matter where the orbit of the planet placed. That means the velocity of every planet is not same. It varies along with the orbit. But every time the change of area is constant.

<u>Third law</u>: The orbital period of the planet is proportional with the cube of the semi major axis of the planet. It can be shown mathematically,

p²∝a³

Where we know,

p= The orbital period of the planet.

a= the semi major axis of the planet.

From the discussion we can easily shown that there are three laws of Kepler about planetary motion.
