Water vapor is an example of what type of solution?
Answer:
Explanation:
A solution means it is a 'homogenous' mixture. That is its composition and properties are uniform throughout the mixture. In case of water vapour in air(and also dust in air) it is not a homogenous mixture therefore cannot be considered as a solution.
Answer:

In a fixed volume, when temperature decreases, pressure
Explanation:
the pressure increases. Because the temperature of a gas is proportional to the average kinetic energy of the gas molecules. The particles moving faster collide with the walls of the container frequently with greater force. This causes the force on the walls of the container to increase so as the pressure increases.

A spring with a spring constant of 400 n/m has a mass hung on it so that it stretches 10 cm. calculate how much mass the spring is supporting?
Answer:
4.1 kg
Explanation:
We'll begin by calculating the force acting on the spring.
Spring constant (K) = 400 N/mExtension (e) = 10 cm = 10/100 = 0.10 mForce (F) =?F = Ke
F = 400 × 0.10
F = 40 N
Finally, we shall determine the mass. This can be obtained as follow:
Force (F) = 40 NAcceleration due to gravity (g) = 9.8 m/s²Mass (m) =?m = F / g
m = 40 / 9.8
m = 4.1
Therefore, the mass the spring is supporting is 4.1 kg
About % of the population of a large country is. If two people are randomly selected, what is the probability both are ? what is the probability at least one is ? assume the events are independent
Using the binomial distribution, it is found that there is a:
0.0036 = 0.36% probability that both are allergic to pollen.0.1164 = 11.64% probability that at least one is allergic to pollen.What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.Researching the problem on the internet, it is found that:
6% of the population is allergic to pollen, hence p = 0.06.Two people are chosen at random, hence n = 2.The probability that both are allergic is P(X = 2), hence:
P(X = 2) = 0.06^2 = 0.0036.
0.0036 = 0.36% probability that both are allergic to pollen.
The probability of at least one is:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.94^2 = 1 - 0.8836 = 0.1164.
0.1164 = 11.64% probability that at least one is allergic to pollen.
