the black plague took a toll no the population back then and claimed alot of lives
Answer:
Explanation:a) low melting point
Poor conductivity
: Low solubility
Low solubility The mass is equal to the sum of the masses of all the individual atoms in the molecular structure.
b) The cross-sectional area of the fluid.
Therefore The diffusion coefficient is a physical constant dependent on molecule size and other properties of the diffusing substance as well as on temperature and pressure.
If both of them were travelling anti parallel to each other. (parallel but in opposite directions)
Answer:
A nerve impulse
Explanation:
It's important to note that these signals not only connect the brain and spinal cord, but they also send signals to muscles and glands. People talk about nerve impulses when they talk about the electrical signal that goes down an axon.
Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.
Given;
x + y + z = 140 metersAccording to the proportion theorem,

Solving for x, using cross multiplication:

Similarly,
x/40 = z/35
solving for z by cross multiplication,
z = 35x/40
z = 7x/8
Now, the third proportions,
y/30 = z/35
Solving for y,
y = 30z/35
y = 6z/7
x + y + z = 140
4y/3 + 6z/7 + 7x/8 = 140
(224y + 144z + 147x)/168 = 140
224y + 144z + 147x = 23520
Substitutoing z = 7x/8,
224y + (144 × 7x/8) + 147x = 23520
224y + 126x + 147x = 23520
224y + 273x = 23520
Now,
Substitute y = 3x/4
(224×3x/4) + 273x = 23520
168x + 273x = 23520
441x = 23520
x = 53.33
Now,
We know that
y = 3x/4
so,
y = 40
And,
z = 7x/8
Z = 46.66
