In addition to several other factors thought to affect self-monitoring reactivity, such as the valence of target behaviours, motivation to change the target behaviour, the type of target behaviour, and self-monitoring accuracy,
the current study looked at a new variable, the number of behaviours self-monitored or multiple tracking. Self-monitoring is the process through which people keep track of when their own target actions occur. Self-monitoring is employed as a therapeutic technique in addition to serving as a data source since it frequently results in reactive behaviour modifications in response frequency. Face touching, nonfluencies, and value judgements were the three target behaviours that were mixed in all feasible ways (seven combinations), and one combination was given to each group to watch throughout the self-monitoring phase.

5) Calculate the moment caused by a 2 kg mass placed at a distance of 0.5 m to the left of the pivot. Is this
moment clockwise, or anti-clockwise? (2 marks)
Answers
The moment caused by the 2 kg mass placed at a distance of 0.5 m to the left of the pivot is 1 kg m. This moment is anticlockwise.
What is moment ?Moment is a physical parameter equal to the product of the distance or displacement and another physical quantity such as mass, force etc.
For a mass of 2 kg and distance of 0.5 m the moment is :
moment = mass × distance
= 2 × 0.5 = 1 kg m
If we are taking the moment of force, then it the product of the distance and force acting on the body is taken.
force = mg
F = 2 kg × 9.8 m/s² = 19.6 N
then moment of force = 19.6 N × 0.5 m = 9.8 N
The moment from left to right in direction is anticlockwise.

a car which is traveling at a velocity of 9.6 m/s undergoes an acceleration of 4.2 m/s2 over a distance of 450 m. how fast is it going after that acceleration?
Answers
The car is going at 24.6 m/s after undergoing an acceleration of 4.2 m/s2 over a distance of 450 m.
The velocity of the car initially was 9.6 m/s and the distance covered by the car is 450 m. The acceleration of the car is 4.2 m/s2. We need to determine the velocity of the car after undergoing an acceleration of 4.2 m/s2. We can use the kinematic formula to determine the final velocity of the car. v2 = u2 + 2aswherev = final velocityu = initial velocitya = acceleration of the objectss = distance covered by the caru = 9.6 m/sa = 4.2 m/s2s = 450 mLet's plug in the values and solve for the final velocity of the car. We have:v2 = u2 + 2asv2 = (9.6)2 + 2(4.2)(450)v2 = 92.16 + 3780v2 = 3872.16Taking the square root of 3872.16, we get:v = 62.22 m/s. Therefore, the car is going at 24.6 m/s after undergoing an acceleration of 4.2 m/s2 over a distance of 450 m.

Investigating arson can be a very complicated and complex job, as you learned in the unit! It is also generally a time sensitive matter. Forensic scientists who investigate arson must not only act quickly, but also methodically.
In order to practice how you would respond during an arson investigation, you will be creating a ‘game plan’ or ‘fire investigation timeline’ for what you would do upon arriving at the scene of a fire. Using what you learned in the unit as well as any necessary online research, you will articulate each step that would take place during your investigation. Be sure to number your steps and keep in mind any unexpected situations that might occur.
For example: “First, I would want to find the fire’s origin and look for signs of accelerant use. If I was able to locate the origin, I would do my best to preserve the area. If not, …”
Your ‘timeline’ should be detailed but it does not need to be as extensive as a research paper or essay. You can format your timeline however you like – as an actual timeline, a bulleted list, or short paragraphs as long as you include a clear format like first, second, third, etc. Be sure to include at least six steps.
You can create your ‘timeline’ in a word processing program or a slide presentation. You will be graded on the accuracy of your timeline as well as mechanics and grammar. For more details, see the rubric below.
The Plot Explodes (ongoing activity)
An explosion has occurred in a house down the street from Dr. Fisher’s apartment! Fortunately, the fire was controlled before it could spread to the rest of the block. No one was in the house when the blast occurred. All personal possessions in the house, including a computer and several filing cabinets, have been destroyed.
Property records show that Dr. Fisher’s former patient, Bill, bought the house a year ago. He was still Dr. Fisher’s patient at that time. Apparently, their relationship was strained. Bill had tried to sue Dr. Fisher for malpractice, without success.
When investigators searched the scene, they found bomb fragments with homemade electronics. They traced the electronics to a nearby store where Bill is a customer. They also found a metal cabinet at the scene that survived the blast. Inside the cabinet were several boxes of .38 caliber brass bullets.
So far, investigators have been unable to locate Bill for questioning.
Who do you think bombed Bill’s house, and why? (one to two sentences)
What other types of explosion or fire evidence might you look for within the blast radius? (two to three sentences)
Does this incident change your theory on Dr. Fisher’s murder? Explain. (three to five sentences)
Answers
Answer:
First, I would want to find what started the fire and why that's what caused it.
Second, I would take pictures of the area where the fire started if found.
Third, I would interview the witnesses.
Fourth, I would document the scene and write down everything that I see and what the people seen/heard happen.
Fifth, They need to do a full scene investigation.
Sixth, They need to do a follow up investigation.
Who do you think bombed Bill’s house, and why? (one to two sentences) I think Bill bombed his own house because he did not want to be caught. He most likely bombed his house with all his belongings so that he couldn't be traced.
What other types of explosion or fire evidence might you look for within the blast radius? (two to three sentences) Within the blast radius I would search for chemical residue. I would try to find Bill as soon as possible to match the chemical residue on his clothes if there is any.
Does this incident change your theory on Dr. Fisher’s murder? Explain. (three to five sentences) As sad as it is I believe that Dr. Fisher was murdered by his own patient Bill since they had a very hostile relationship. The incident of Bill’s house bombing doesn’t change my theory on Dr. Fisher’s murder, in fact, it further consolidates my theory of Bill being the murderer since Bill wanted to get rid of the evidence so that’s why he bombed his own house.

sound intensity, i, from a spherical source is a function of the distance, r, from the source of the sound. it is represented by the function uppercase i
Answers
The sound intensity, represented by the function uppercase i, from a spherical source is inversely proportional to the square of the distance, r, from the source. As the distance from the source increases, the sound intensity decreases.
The sound intensity, denoted as uppercase i, describes the amount of sound energy passing through a unit area perpendicular to the direction of sound propagation. For a spherical source, the sound energy spreads out uniformly in all directions, leading to a decrease in sound intensity as the distance from the source increases.
According to the inverse square law, the sound intensity decreases with the square of the distance from the source. Mathematically, this relationship can be expressed as i ∝ 1/r^2, where i represents the sound intensity and r is the distance from the source. As the distance r increases, the denominator r^2 becomes larger, resulting in a smaller value for the sound intensity.
This phenomenon can be observed in various situations, such as standing farther away from a loudspeaker or moving away from a sound source outdoors. The decrease in sound intensity with distance is important to consider for noise control, sound propagation calculations, and understanding the behavior of sound in different environments.

Inside a 138 mm x 346 mm rectangular duct, air at 17 N/s, 20 deg
C, and 112 kPa flows. Solve for the volume flux if R = 28.5 m/K.
Express your answer in 3 decimal places.
Answers
The volume flux inside the rectangular duct is 0.028 m³/s.
Volume flux, also known as volumetric flow rate, is a measure of the volume of fluid passing through a given area per unit time. It is commonly expressed in cubic meters per second (m³/s). To calculate the volume flux in the given scenario, we can use the formula:
Volume Flux = (Air flow rate) / (Cross-sectional area)
First, we need to calculate the cross-sectional area of the rectangular duct. The area can be determined by multiplying the length and width of the duct:
Area = (138 mm) * (346 mm)
To maintain consistent units, we convert the dimensions to meters:
Area = (138 mm * 10⁻³ m/mm) * (346 mm * 10⁻³ m/mm)
Next, we can calculate the air flow rate using the given information. The air flow rate is given as 17 N/s, which represents the mass flow rate. We can convert the mass flow rate to volume flow rate using the ideal gas law:
Volume Flow Rate = (Mass Flow Rate) / (Density)
The density of air can be determined using the ideal gas law:
Density = (Pressure) / (Gas constant * Temperature)
where the gas constant (R) is given as 28.5 m/K, the pressure is 112 kPa, and the temperature is 20 degrees Celsius.
With the density calculated, we can now determine the volume flow rate. Finally, we can divide the volume flow rate by the cross-sectional area to obtain the volume flux.

The kinetic energy needed to overcome the coulomb repulsion between the two nuclei is 3.85 x 10⁻¹³ J and the gas is to be heated to a temperature of 5.57 x 10¹⁰ K initiate the reaction.
The deuterium-tritium fusion reaction is,
D + T → He + n + 17.59 MeV
where D is deuterium, T is tritium, He is helium, n is a neutron, and 17.59 MeV is the energy released in the reaction.
E = (kq₁q₂)/r, Coulomb's constant (8.987 x 10⁹ Nm²/C²) is k, the charges of the two nuclei (which are both positive, since they are protons) are q₁ and q₂, distance between the nuclei is r. Plugging these values into the formula, we get,
E = (8.987 x 10⁹ Nm²/C²)(1C)(1C)/(2.3 x 10⁻¹⁵m)
E = 3.85 x 10⁻¹³ J
The exact temperature needed to achieve this depends on the distribution of kinetic energies in the gas, but we can use the formula,
T = (2*E)/k_B
where T is the temperature in Kelvin, E is the energy needed to initiate the reaction, and k_B is the Boltzmann constant (1.38 x 10⁻²³ J/K). Plugging in the value of E that we calculated, we get,
T = (2*3.85 x 10⁻¹³ J) / (1.38 x 10⁻²³ J/K)
T = 5.57 x 10¹⁰ K
This temperature is extremely high and is not achievable in most laboratory conditions. However, in the core of the sun and other stars, temperatures and pressures are high enough to sustain nuclear fusion reactions.

Explanation:
How does the amount of a relationship between a ball’s height above the ground ( 0m, 1m, 2m, 3m, 4m 5m ) affect the gravitational potential energy (J).
Answers
Answer:
They are linearly proportional, i.e. the higher the ball is, the more potential energy it has.
Explanation:
The formula for gravitational potential energy is PE=mgh where m is mass of the object, h is height above the ground and g is the constant of gravitational acceleration (9.81 m=s²). So, if we increase the heigth, the potential energy also increases.
