The positions of the peaks and dips in its spectrum provide evidence about the ELEMENTAL COMPOSITION of an object. Each element can absorb light at determined wavelengths.
Each element can absorb light rays at determined wavelengths because elements are composed of different atoms.
Spectroscopy is a field of study focused on the interaction between the atoms of an element and electromagnetic radiation as a function of the wavelength.
This field (spectroscopy ) studies the absorption and emission spectra of light by matter, which can be used to determine the elemental composition of an object.

The time that customers wait to be served at the deli for a grocery store follows the uniform distribution between 0 and 7 minutes. What is the probability that a randomly selected customer will wait more than 4 minutes at the deli?.
The probability that a randomly selected customer will wait more than 4 minutes at the deli is given below
The probability that a randomly selected customer will wait more than 4 minutes = [tex]0.4286[/tex]The waiting time for the customers is uniformly distributed between 0 - 7 minutes
Consider a random variabe X that represents the waiting time of customers and uniformly distributed between 0-7 minutes
Therefore, the density function of X is determined as
[tex]f(x) = \frac{1}{b-a}\\\\f(x) = \frac{1}{7-0}\\\\f(x) = \frac{1}{7}[/tex]
The probability that the customer will wait more than 4minutes,
[tex]P(X>4) = \int\limits^7_4 f{x} \,dx\\\\= \int\limits^7_4 \, \frac{1}{7}dx\\\\= \frac{1}{7} * [x]^7_4\\\\= \frac{7-4}{7} \\\\= 0.4286[/tex]

Which of the following would have the largest concentration of chloride ions in solution.
Answer:
From the given options, the solution of 0.10M AlCl₃ is the one that has the highest concentration of chloride ions.
To know which of the given solutions has the highest concentration of chloride ions, we must evaluate each of them.
1) 0.10 M MgCl₂
We can see that in 1 mol of MgCl₂, we have 1 mol of Mg²⁺ and 2 moles of Cl⁻ ions, so if the initial concentration of MgCl₂ is 0.10 M we have:
Hence, in this solution we have 0.20 M of chloride ions.
2) 0.10 M AlCl₃
In 1 mol of AlCl₃, we have 1 mol of Al³⁺ and 3 moles of Cl⁻, so the concentration of Cl⁻ is:
Then, the concentration of chloride ions in this solution is 0.30 M.
3) 0.05 M CaCl₂
We can notice that in 1 mol of CaCl₂ we have 1 mol of Ca²⁺ and 2 moles of Cl⁻. The concentration of Cl⁻ is:
So, the concentration of the Cl⁻ ions is 0.10 M.
4) 0.10 M LiCl
In this case, in 1 mol of LiCl we have 1 mol of Li⁺ and 1 mol of Cl⁻, so the concentration of the chloride ions is:
Hence, in this solution the concentration of the Cl⁻ ions is 0.10 M.
Therefore, the solution 0.10M AlCl₃ has the highest concentration of chloride ions.

Place the events that form hurricane-force winds in order.
Answer: The events that form hurricane-force winds are as follows
1. Tropical disturbance
2. Tropical depression
3. Tropical storm
4. Hurricane.
Explanation:
All of the above-mentioned events happen in chronological order for the hurricane-force winds to occur.
1. Tropical disturbance occurs from the tropics and the subtropics. These are generally 100-300 miles in diameter. It is a tropical weather system of organized conventions. This is the first stage that consists of a loosely organized low-pressure area.
2. Tropical depression is a more organized deep convention and has a closed circulation of sustained winds of less than 39 mph.
3. Tropical storm is the third stage that has sustained winds between 39 - 73 mph.
4. The hurricane is created when the sustained winds finally reach or cross the speed of 74 mph.
This is how hurricane-force winds are created.

A 1. 5-kilogram lab cart is accelerated uniformly from rest to a speed of 2. 0 meters per second in 0. 50 second. What is the magnitude of the force producing this acceleration?.
The magnitude of the force producing this acceleration is found to be 3.0 N.
What is Force?Force may be defined as the process of pushing and pulling an object with an appropriate mass in order to cause it to change its velocity with respect to time.
Force is a vector quantity as it has both magnitude and direction. Force is an external agent which is generally capable of changing a body's state of rest or motion with respect to time.
According to the question,
The total mass of an object = 1.5 kg.
The speed of an object = 2.0 m/sec.
So, the formula for calculating the magnitude of the force is as follows:
Force = Mass × Acceleration.= 1.5 kg × 2.0 m/sec = 3.0 N.
Therefore, the magnitude of the force producing this acceleration is found to be 3.0 N.

Which image do you think best illustrates the tragedy of the fire? why? give at least three reasons for your choice in your response.
9-13 and 17
Pictures 9-13 actually show dead people, who died trying to escape the fire. These were people who had lives, families, etc. who never knew that an ordinary work day would turn tragic. The sheer number of people seen truly shows how horrific of an event this was, with their bodies being broken and lifeless.
17 shows the aftermath of the fire. What was once a busy, bustling workplace full of life was now lonely and deserted, with the ashes of equipment, clothing, and crushed memories. The scorched-black room and messy area really give off that "neglected and forgotten" feel. Even the officer contributes to the empty feel of the room, as he's the only one seen there, all alone.
Pictures 9 through 13 show actual deceased victims who perished while attempting to flee the fire. These were folks with families, lives, and other responsibilities who had no idea that a routine workday would end tragically.
What is Fire?The observable result of the combustion process, a unique kind of chemical reaction, is fire. It happens when some kind of fuel and atmospheric oxygen are combined. The end result of the chemical reaction is entirely distinct from the initial component.
The heat from the heat causes some of the cellulose material that makes up the wood to break down when the wood reaches about 300 degrees Fahrenheit (150 degrees Celsius).
The molecules of the complex disintegrate at a temperature of roughly 500 degrees F (260 degrees C) for wood, at which point the atoms recombine with oxygen to generate water, carbon dioxide, and other products. They burn, in other terms.
