(1.5 m^3) • (1.05 kg/m^3) = 1.575 kg. That's quite a bag you've got there ! 1 m^3 is like 264 gallons of blood. Hope the poor patient survives the transfusion.
Also, the actual density of blood is around 1.05 g/cm^3, or 1050 kg/m^3.
The blood they're giving the guy in this question is about 18% less dense than the AIR in his hospital room, and they're pumping 264 gallons of it into him. Maybe THAT'S his whole problem.
The law of definite proportion states that any sample of the compound will always have the same percentage of each element by weight or mass.
There are four elements that made up matter: air, water earth, and fire is not the main idea of dalton's atomic theory.
<h3>What is the law of definite proportion?</h3>
The Law of Definite Proportion defines that the elements that composed a chemical compound are generally arranged in a definite mass ratio regardless of preparation.
The composition of compounds will always be the same by mass using the law of definite proportions. Chemical compounds are made of elements that are present at fixed ratios in terms of their mass.
In the nitrogen dioxide molecule (NO₂), Nitrogen and oxygen atoms are always present in a 1:2 ratio.
According to Dalton's atomic theory, all matter consists of atoms. The atoms of the same element have the same mass and the atoms of different have different masses and compounds are made of atoms of more than one element.
Therefore, for question (1) option (C) and for (2) option (C) is correct.

Well uhhh if you’re a sub watcher I totally recommend Classroom of the Elite- it’s in crunchy roll, or Soul eater- that’s what I’m currently watching. Or Aot Junior- it’s on Hulu.
Answer:
Explanation:
An object's resistance depends on its form and the substance it is made from. The electrical resistance R of the cylinder, as you might expect, is directly proportional to its length L, similar to a pipe's resistance to fluid flow. The longer the cylinder, the more charges of collisions with its atoms can occur. The bigger the cylinder diameter, the more current it can carry.
Answer:
35 revolutions
Explanation:
t = Time taken
= Final angular velocity
= Initial angular velocity
= Angular acceleration
= Number of rotation
Equation of rotational motion
Number of revolutions in the 10.7 seconds is 17.13806
Number of revolutions in the 11.2 seconds is 17.36035
Total total number of revolutions in the 21.9 second interval is 17.13806+17.36035 = 34.49841 = 35 revolutions
