The head of a giraffe is 2.0 m above its heart and the density of the blood is 1.05 103 kg/m3. what is the difference in pressur

erastovalidia [21]

The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:

<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>

Antibiotic resistance has become a major problem worldwide.

castortr0y [4]

Answer:

Educating people on the use of antibiotics

Explanation:

Antibiotics are becoming less effective because patients are not taking their full courses and providers are over prescribing them. Many people demand antibiotics not knowing that they are not useful for treating viral and fungal infections, thus allowing the bacteria already present inside of them to develop resistance. This also happens when a patient doesn't take all of their antibiotics. They may think that they feel fine after a few days of taking antibiotics and that they no longer have to take them, but in reality they are not free from the disease causing bacteria. The bacteria then have a chance to multiply again, this time with resistance to the treatment. Educating patients on conditions like sepsis and their mortality will help with medication adherence to decrease the likelihood of antibiotic abuse

Newton's universal law of gravitation states that all objects attract each other with a force directly proportional to their masses and inversely proportional to the square of the distance between their centers. When considering objects on the surface of the Earth, the force is directly proportional to the product of the mass of the object and the acceleration due to gravity at the Earth's surface. Since the Earth is larger than any other object under consideration, the object is drawn toward the Earth.

Explanation:

The magnitude of the gravitational force between two objects is given by Newton's universal law of gravitation:

$F=G\frac{m_1 m_2}{r^2}$

where :

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

This force is always attractive.

At the Earth's surface, this can be rewritten as

$F=mg$

with

$g=\frac{GM}{R^2}$

where M is the mass of the Earth, R is its radius, and m the mass of the object.

g is called acceleration due to gravity and it is the value of the acceleration due to the force of gravity of any object near the Earth's surface (its value is approximately $9.81 m/s^2$ . Since the Earth is much more massive than any other object, the object is attracted towards the Earth (so, it accelerates towards it); the Earth is also attracted by the object, however, being its mass so large, its acceleration is negligible.
