10°c
Explanation:
Given parameter;
Lower fixed point = 30mm
Upper fixed point = 180mm
Reading = 45mm
Unknown:
The degree celcuis temperature at 45mm = ?
Solution:
To solve this problem we simply compare the mm- scale to the celcius - scale that we know.
The upper fixed point is the boiling point of water
Lower fixed point is the freezing point of water
This shows that both the upper and lower fixed point of both thermometers are the same;
mm-scale °c scale
180mm 100°c
45mm x
30mm 0°c
Solving;

x (150) = 100 x 15
x = 10°c

Answer: 3.48g
Explanation:
here, we will be using conservation of momentum to solve the problem. i.e the total momentum remains unchanged, unless an external force acts on the system. We'll in thus question, there is no external force acting in the system.
Remember, momentum = mass * velocity, then
mass of blood * velocity of blood = combined mass of subject and pallet * velocity of subject and pallet
Velocity of blood = 56.5cm = 0.565m
mass of blood * 0.565 = 54kg * (0.000063/0.160)
mass of blood * 0.565 = 54 * 0.00039375
mass of blood * 0.565 = 0.001969
mass of blood = 0.00348kg
Thus, the mass of blood that leaves the heart is 3.48g
