The thickest and strongest chamber in the human heart is the left ventricle, responsible during systole for pumping oxygenated blood through the aorta to rest of the body. Assume aortic blood starts from rest and accelerates at 22.0 m/s2 to a peak speed of 1.01 m/s.

(a) How far does the blood travel (in m) during this acceleration?

m

(b) How much time (in s) is required for the blood to reach its peak speed?

s

(a). The blood travel during this acceleration is 0.0231 m.

(b). The time for the blood to reach its peak speed is 0.0459 sec.

Explanation:

Given that,

Acceleration = 22.0 m/s²

Speed = 1.01 m/s

(a). We need to calculate the distance

Using equation of motion

Where, v = final speed

u = initial speed

a = acceleration

s = distance

Put the value into the formula

(b). We need to calculate the time

Using equation of motion

Put the value into the formula

Hence, (a). The blood travel during this acceleration is 0.0231 m.

(b). The time for the blood to reach its peak speed is 0.0459 sec.

During 15 and 16 th century Spain as a beautiful country. they traded goods across the Atlantic ocean.

Explanation:

Spanish empire was very big with a strong naval force. It fought against Ottoman empire, France and in America, Spain wanted its colonies to be independent. Due to the rise of the Portuguese and European powers, Spain lost most of its territories.

Roman Catholic churches were famous in Spain which were brought to America too due to the colonization. Together with Portuguese, Spain entered many international trades. Spanish empire began from 16th century after the arrival of Christopher Columbus after which famous Aztec, Inca and Mayan empire can be seen even today.
