Which refers to the measure of the amount of water vapor in the air?
Answer:
humidity
Explanation:
According to Maslow's hierarchy of needs, the basic needs are what we call physiological or biological needs. The survival of the individual relies on these basic needs. Looking at it this way, before you can meet any of the needs going up the hierarchy, one needs to be healthy or at least functional optimally to even get started. All other needs are considered secondary until the basic needs have been me
Answer:
True
Explanation:
|ndeed, Psychologist Abraham Maslow's sought to describe hierarchy in which the average (or most) humans place their needs. In other words, he believes we as humans have basic needs which we long to satisfy.
On the ranking or hierarchy, according to Maslow the need humans satisfy first is their physiological need. Here's the full hierarchy:
Physiological Needs
↓
Safety Needs
↓
Love/Belonging Needs
↓
Esteem Needs
↓
Self-Actualization
Knowing how fossils form, do you think it’s likely that humans will ever piece together a complete fossil record for every species that ever existed on Earth? Why or why not?
Answer:
yes
Explanation:
since humans dig out the earth for resources o believe that fossils far every species that exists and is extinct will be found and will be pieced together

What is the answer
help plz this is part b to my last question
Answer:
% error Aluminum: 0.34%
% error Steel: 16.67%
% error Lead: 23.08%
Explanation: Given our observed values of specific heat, to find the % error, we must know the true values as well. % error can be defined as, % error = |observed value - true value | / true value.
Our given data to solve this problem is as follows:
Aluminum Specific Heat Observed Value: 0.9 (given), Aluminum Specific Heat True Value: 0.897 (research).
Steel Specific Heat Observed Value: 0.49 (given), Steel Specific Heat True Value: 0.42 (research).
Lead Specific Heat Observed Value: 0.16 (given), Lead Specific Heat True Value: 0.13 (research).
___________
Since we have all the information, just subtract the true value from the observed value, and divide by the true value.
Aluminum Specific Heat % error:
observed value - true value / true value →
0.9 - 0.897 / 0.897 = 0.003 / 0.897 = 1/299 ≈ 0.34 %
Steel Specific Heat % error:
observed value - true value / true value →
0.49 - 0.42 / 0.42 = 0.07 / 0.42 = 1/6 ≈ 16.67%
Lead Specific Heat % error:
observed value - true value / true value →
0.16 - 0.13 / 0.13 = 0.03 / 0.13 = 3/13 ≈ 23.08%

How could measuring the melting point of a solid help decide whether it was a mixture or a compound?
Answer: It can't.
Explanation:
In most cases, the melting point alone will not enable you to identify a compound. Millions of solid organic compounds, and their melting points, are known. Perhaps 10,000 of these will have the same melting point as your unknown compound.

The gravitational attraction between two objects is determined by the mass of the two objects and the:
A. Distance between the objects
B. Weight of the objects
C. Diameter of the objects
D. Density of the objects
Answer:
A. Distance between the objects
Explanation:
The gravitational attraction between two objects is determined by the mass of the two objects and the distance between the two objects.
According to Newton's law of universal gravitation:
"the gravitational force of attraction between two bodies is directly proportional to the product of the their masses and inversely proportional to the square of the distance between them".
F = [tex]\frac{Gm_{1}m_{2} }{r^{2} }[/tex]
F is the gravitational attraction
G is the universal gravitation constant
m is the mass
r is the distance
We can see that the gravitational attraction depends on the mass of the bodies and the distance between them.

Two liters of hydrogen gas are stored at a
pressure of 100 kPa. If the temperature
does not change, what will the volume
of the gas be when the pressure is
decreased to 25 kPa?
Answer:
the volume will expand
Explanation:
gas under pressure contracts, and expands with a lesser pressure
The volume of the hydrogen gas at 25 kPa is 8 Liters.
Explanation:
Given:
At constant temperature, 2 liters of hydrogen gas at 100kPa pressure.
To find:
The volume of the hydrogen gas at 25kPa.
Solution:
The initial pressure of the hydrogen gas =[tex]P_1=100 kPa[/tex]
The initial volume of the hydrogen gas at 100 kPa =[tex]V_1=2 L[/tex]
The final pressure of the hydrogen gas =[tex]P_2=25 kPa[/tex]
The final volume of the hydrogen gas at 25kPa = [tex]V_2=?[/tex]
Using Boyles law:
[tex]P_1V_1=P_2V_2\\100kPa\times 2 L=25 kPa\times V_2\\V_2=\frac{100 kPa\times 2L}{25 kPa}=8L[/tex]
The volume of the hydrogen gas at 25 kPa is 8 Liters.

How many atoms in 134 moles of an element B?
Answer:
8.06966961e+25
Explanation:
Atom = Mole / 6.0221415E+23
1 Mole = 6.0221415E+23 Atom
Answer:
8.06948e+25 atoms
Explanation:
mole = number of particles/avogadro number
number of atoms = mole × avogadro number
number or atoms = (134) x (6.022× 10²³) = 8.06948e+25 atoms
