Answer: Mean Arterial Pressure is directly proportional to Cardiac Output and Systemic Vascular Resistance and also directly proportional to Central Venous Pressure.
Explanation: Based on the relationship of flow, pressure and resistance, the mean arterial pressure is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP). This relationship is given by:
MAP = (CO x SVR) + CVP
Which is alternatively expressed as:
MAP = CO x SVR (this is because at any point in time in blood circulation, the central venous pressure is always near to zero mmHg.
Due to this direct relationship, any factor affecting the cardiac output and the Systemic Vascular Resistance would cause a corresponding change in the Mean Arterial Pressure.
It is also worthy to note that If Cardiac Output and Systemic Vascular Resistance change reciprocally (inversely) and proportionately, then Mean Arterial Pressure will not change. The plotted graph is one of positive slope.
The whole relationship occurs when blood is pumped out of the left ventricle into the aorta and distributing arteries, creating pressure.
Answer:
n = 87 the number of people can raft hold
Explanation:
The raft is made of 10 logs
No given the information to find the average person assuming
w = 69 kg , wₙ = 0.60
e = 56 cm * 1 / 100 cm = 0.56 m
l = 6.1 m
V = 10 * 6.1m * (0.56m /2) ² π
V = 15.024 m³
m₁ = V * L³ * wₙ + mₙ
m₂ = V * L³
m₁ < m₂
n < V * (1 - wₙ) * L₃ / w
n < 15.024 m³ * ( 1 - 0.60) * 10³ / 69 kg
n ≅ 87
Is the number of maximum people
Answer:
hi Ashley can we be friends am Sam
Answer:
166.67 ohm
Explanation:
Complete statement of the question is :
You have a collection of six 1.0 kO resistors. What is the smallest resistance you can make by combining them?
When we connect resistors in parallel, the combination resistance is always smaller than the smallest resistance value we combine.
Parallel Combination of resistances is given as
where
= Equivalent resistance
and 
are resistances in parallel.
So for the above question, we have
So parallel combination is given as
So the smallest resistance is 166.67 ohm
