When you urinate, you increase pressure in your bladder to produce the flow. For an elephant, gravity does the work. An elephant

Answer:

R₂ / R₁ = D / L

Explanation:

The resistance for a metal can be calculated by

        R = ρ L / A

Where ρ indicates the resistivity of aluminum, L is the resistance's length, and A indicates the cross-sectional area

We use this formula for both configurations

For small face measurements (W x W)

The length is

         L = W

Area  

         A = W W = W²

         R₁ = ρ W / W² = ρ / W

For larger face measurements (D x L)

       Length L = D= 2W

       Area     A = W L

     R₂ = ρ D / WL = ρ 2W / W L = 2 ρ/L

From this, we find the relation to be

    R₂ / R₁ = 2W²/L

The previously accepted theory that was proven incorrect is the Geocentric Theory, which placed Earth at the center of the universe. This idea was introduced by philosopher Ptolemy. He formulated this hypothesis based on his observations that celestial bodies such as the Sun, stars, and the moon appeared to move around Earth from our vantage point. However, Galileo Galilei contradicted this notion with his Heliocentric Theory. He used a telescope to observe that Venus undergoes phases, akin to the moon, leading him to conclude that the alignment of Venus, Earth, Moon, and Sun did not support the earlier theory. 

Answer:

a) Blood mass is

b) The count of blood cells is  

Explanation:

From the problem statement, we learn that

         The blood volume is  

         The density of blood is  

         % of blood which consists of cells is  = 45.0%

        the % of blood that is  plasma is  = 55.0%

        density of blood cells is  

         % of cells that are white is  = 1%

        % of cells that are red is  = 99%

         The red blood cell diameter is  =

         The red blood cell radius is  

The mass is generally represented mathematically as

               

Substituting values

           

               

Cell mass is = 45% of m

                         = 0.45 * 5,7876

                         = 2.60442 kg

The volume of cells is =

                                     

                                     

The white blood cells volume is = 1% of the cells volume

                                                         

                                                       

The volume of a single cell is

                                                                       

                                                                       

The red blood cells volume is

                                                           

                                                           

The total red blood cell count is  

                                                     

                                                   

The total white blood cell count is  

                                                         

                                                         

The overall number of blood cells is  

                                                       

It is stated that, in a typical pulsed-field machine, the magnetic field rises from 0 T to 2.5 T within 200 μs. The change in the magnetic field and time interval are relevant here. The diameter is 2.3 cm, translating to a radius of 0.0115 m. As the magnetic field changes, an induced emf occurs within the ring, determined by: E = 5.19 volts. Thus, the induced emf in the ring equates to 5.19 volts, which is the sought solution.

The moment the body impacts the ground, two types of Forces are produced: the gravitational pull and the Normal Force. This aligns with Newton's third law, indicating that every action has an equal and opposite reaction. If the downward force of gravity is directed toward the earth, the reactionary force from the block acts upwards, equivalent to its weight:

F = mg

Where,

m = mass

g = gravitational acceleration

F = 5*9.8

F = 49N

Consequently, the answer is E.
