Answer:
Explanation:
Appears to be the vertexes of a triangle.
AB = √(-6 - (-2))² + (3 - 4)²) = √17
AC = √(-6 - (-8))² + (3 - 3)²) = 2
BC = √(-2 - (-8))² + (4 - 3)²) = √37
The correct answer is exothermic. An exothermic reaction is a reaction that releases heat, and therefore it transfers heat to the surroundings (in this case, the tube), making it warmer. Instead, in an endothermic reaction, the heat is absorbed by the reaction.
Answer:
Blood is thicker than water due primarily to the presence of red blood cells
Answer: <u>This is because it becomes more dense when cells are added</u>

It means that 19.3g of gold is packed into 1cm^3.
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
