The uterus gets ready to nurture a fertilized egg by
lukranit [14]
By flooding the uterus with a rich supply of blood for the tissue that lines the inner side of the uterus and it is called the endometrium. This happens each month during the menstrual cycle, when the body with the help of hormones which have different levels in the different times of the cycle. When it is time to prepare the uterus for a fertilized egg, the blood vessels of the endometrium swell and supply more blood to the tissue. 

In the case that a fertilized egg cell reaches the uterus, it will attach itself to the endometrium and this is the place where the fetus, and then the baby will start growing. The endometrium is the base for the growth of the placenta which is the main and most important factor for protection and nutrition of the baby.

A hydraulic jack has a small piston area A1 = 2 m^2 and the large piston area A2 = 20 m^2. A 1500 Kg car needs to be lifted. a)
Alex777 [14]

Answer:

1471.5 Newton

10

Explanation:

Small piston area = A₁ = 2 m²

Large piston area A₂ = 20 m

m = Mass of car = 1500 kg

g = Acceleration due to gravity = 9.81 m/s²

Force

F = mg = 1500×9.81 = 14715 N

Force applied by car is 14715 N

a) Pascal's law

\frac{F_1}{A_1}=\frac{F_2}{A_2}\\\Rightarrow F_1=F_2\frac{A_1}{A_2}\\\Rightarrow F_1=14715\frac{2}{20}=1471.5

Force required is 1471.5 Newton

b) Mechanical advantage

\frac{F_2}{F_1}=\frac{14715}{1471.5}=10

Mechanical advantage is 10

What is the density of iron if 5.0 cm3 has a mass of 39.5g
weqwewe [10]

Answer :\rho = 7.9\ g/cm^3

Explanation :

It is given that

Mass of iron, m = 39.5 g

Volume of iron, V = 5\ cm^3

So, density is :

density, \rho =\dfrac{mass}{volume}

\rho =\dfrac{39.5g}{5cm^3}

\rho = 7.9\ g/cm^3
