We can actually deduce here that the important points to consider when conducting the described data collection are:
- The exact temperature at which the crickets chirped less.
- The exact temperature the crickets chirped more.
- Other forces that influence the chirping of the crickets e.g: weather condition, human factor, environmental noise, etc.
<h3>What is data collection?</h3>
Data collection is actually known to be the process of collecting data, information or statistics for the purpose of research and documentation.
Data collection is actually important when research projects are being carried out.
We see that it is very important to note that when carrying out the data collection in Pinky's science fair project, the above important points should be noted or observed.

We are given that the specific heat of water is 4.18 J / g
°C. We know that the molar mass of water is 18.02 g/mol, therefore the molar
heat capacity is:
molar heat capacity = (4.18 J / g °C) * 18.02 g / mol
<span>molar heat capacity = 75.32 J / mol °C</span>
Answer:
Ionic bond
Explanation:
When Na loses an electron, it becomes positive ion.
When Cl gains an electron, it becomes negative ion.
The electrostatic attraction between these ions is an ionic bond.
Transverse wave:
⇨- the way the wave is moving
⟶- Medium - the material it is traveling through
冖- Wavelength - the distance from crest to crest
C - Crest - the highest point on a wave
T - trough - the lowest part on a wave
↕️ - Amplitude - the distance from rest to crest
ྊ - (tinfoil)Wave
Description:
In the beginning of the wave the wavelength is short and the frequency is high so is the energy.and the amplitude is low *i believe* And after the mark of T shown on the image the wavelength is long and the frequency is low and so is the energy and the amplitude is high *i believe*.Amplitude and wavelength are both measures of distance.
Longitudinal/Compressional Wave:
KEYS:
⟶-medium - the material it is traveling through
⇨-way the wave is moving
冖-wavelength - the distance from crest to crest
R -Rarefaction - the opposite of compression
C-Compression - particles are closest together
The total number of matchbooks required would 5,000 be and the cost would be $144
<h3>Mathematical ratios</h3>
50 matchbooks = $1.44
Each matchbook = 0.005 grams red phosphorus
25 grams of red phosphorus is needed:
25/0.005 = 5,000 matchbooks
5,000 matchbooks will cost:
5000/50 x 1.44 = $144
