Explanation:
We use Hooke's Law, which states that,
F=kx
F- is the force in newtons
k- is the spring constant
x- is the extension of the spring in meters
Solving for k we get k=F/x
k= 10N/0.50m
=100 N/m

Q1. How would you record her BMI in an electronic medical record and would you include any notes?
Q2.What follow-up questions would be appropriate for the 15-year-old girl’s visit to the nutrition clinic, and why? What additional notes, if any, might be appropriate to enter into her electronic medical record, depending on her answers?
Q3.Based on everything you’ve read, which symptoms could indicate an eating disorder that might not be detectable by measuring BMI? What subjective and objective observations could you use to help detect other eating disorders in a clinical setting like the one described in this scenario?
Q4.Based on everything you’ve learned, explain which elements (symptoms, causes, contributing factors, etc.) of bulimia and/or anorexia are biological and physiological, and which are psychological, and which elements are sociological (based on an individual’s place in society, their relationship with other people, and the culture they live in). Include at least one element each for the physiological, psychological, and sociological elements.
Q5.Finally, engage in some independent research to examine BMI in more detail. Look up information that covers the following considerations:
- Limitations of the BMI scale, including considerations related to age, lifestyle, etc.
- How a BMI can be used as part of a “growth chart,” turning it from a one-time absolute measure of health into a dynamic measure of change over time
- How human’s nutrition needs change by age and lifestyle, e.g., do student athletes have different nutrition needs than average students? What about adult athletes?
Part Two i need one paragraph explaining this
The US Department of Agriculture has released an online tool, Choose My Plate, that aims to help people of all ages make healthy nutrition plans for themselves. Other countries have similar programs, so if you live outside the United States, you might see what your local recommendations are. Either way, remember these are just general guidelines, and ideally you would work directly with a physician or dietician to formulate a more individualized dietary plan.
Use the MyPlate Plan calculator on that site to find which calorie level is appropriate for you and follow its link to see your semi-personalized MyPlate plan. Based on the results, write a short paragraph explaining how closely you think your meals matched the proposed plan over the last three days. (If you want to make it even more relevant and you have the time, track everything you eat over the next three days and then write the paragraph. You might find that you get a more precise picture this way.) Are there areas for improvement, and if so, what steps might you take to achieve that improvement? Are there elements about your life that would make it difficult to keep to the proposed plan, like living in a food desert or not having healthy cafeteria options?

Q1. I don't have information on her situation, but an EMR is a medical record that is stored digitally in a secure computer database within an organization or healthcare system. This system allows electronic storage, retrieval, and modification of medical records, and is an alternative to traditional, paper medical records.
Q2. Their food proportions, do they eat every meal, do they eat their vegetables, fruits grains, protein, etc. Check for healthy and unhealthy habits of eating and exercise. Additional notes on medical problems relating to food concerns you may have to look further into based on her answers.
Q3. The info isn't provided, but what I do know is that detection requires awareness of risk factors for, and symptoms and signs of, anorexia nervosa (e.g., participation in activities valuing thinness, family history of an eating disorder, amenorrhea, lanugo hair) and bulimia nervosa (e.g., unsuccessful attempts at weight loss, history of childhood sexual abuse, family history of depression, erosion of tooth enamel from vomiting, parotid gland swelling, and gastroesophageal reflux). Providers must also remain alert for disordered eating in female athletes (the female athlete triad) and disordered eating in diabetics. Treatment requires a multidisciplinary team including a primary care practitioner, nutritionist, and mental health professional. The role of the primary care practitioner is to help determine the need for hospitalization and to manage medical complications (e.g., arrhythmias, refeeding syndrome, osteoporosis, and electrolyte abnormalities such as hypokalemia).

Martin has hypothesized that the size and types of trees differ between valleys and higher elevations. He sets up a transect line in a wooded valley and randomly creates three 10 x 10 meter plots along the transect line, recording GPS coordinates for the northwest corner of each plot. He identifies and measures (diameter at breast height) every tree within the plots. He repeats this procedure in a wooded area on the ridge above the valley.
Using the scenario above, state the independent and dependent variables.
Answer: The dependent Variables include: Size and Types of trees.
The independent Variables include:
geographic elevations that is, valleys and the higher elevations.
Explanation:
The dependent variable simply refers to the variable a researcher tests or measures during an experiment. On the other hand, the independent variable simply refers to the variable that's controlled during an experiment.
Based on the definition above, the dependent variables include the size and the types of trees while the independent variables include the
geographic elevations that is, the valleys and the higher elevations.

3. A bus is moving at 25 m/s when the driver steps on the brakes and brings the bus to a stop in 3.0 seconds. What is the average acceleration of the bus while braking?
Answer:
-8.3 m/s²
Explanation:
The acceleration of an object is defined as the change in velocity over the change in time.
a = Δv/Δt a = (v - v₀)/tWe are given the velocity of the bus, 25 m/s, and the time it takes the bus to stop, 3.0 s.
We know that if the bus stops, its velocity must be 0 m/s. Therefore, we can use these numbers to substitute into the acceleration formula.
a = (25 - 0)/3.0 a = 25/3 a = 8.33333333...The magnitude of the average acceleration of the bus while braking is 8.3 m/s².
However, in order for the bus to slow down and stop, the acceleration must have the opposite sign of the velocity.
This means that the acceleration is negative whilst the velocity is positive. So, the average acceleration of the bus while braking is -8.3 m/s².

We are given:
Mass of the Crate(m) = 71 kg
Applied force(F) = 577 N
Resolving the applied force:
To solve this problem, we will first make a free-body diagram (attached)
The Applied force has been resolved into 2 components denoted by a thinner line and 'g' is the acceleration due to gravity
We found the values by using basic trigonometry
Finding the Normal Force:
Normal force is equal and opposite to the net force applied on the ground. So, we will subtract the vertical component of the applied force from the weight of the crate.
Normal force = mg - F*Sin(27°)
Normal force = [(71)*(9.8)] - [ (577)(0.454) ] [g = 9.8 m/s²]
Normal Force = 433.84 N

The velocity of an object with mass = 2kg is given as a function of time:
V = 2ti + 4[tex]t^{2}[/tex]j
Find the force acting on the object at t = 2 seconds.
Answer:
The force acting on the object at [tex]t = 2\,s[/tex] is [tex]\vec F = (4, 32)\,[N][/tex].
Explanation:
Given that object has a constant mass in time, the force acting on the object ([tex]\vec F[/tex]), in newtons, is defined by following expression:
[tex]\vec F = m\cdot \vec a[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]\vec a[/tex] - Acceleration, in meters per square second.
By definition of acceleration, we know that:
[tex]\vec a = \frac{d}{dt} \vec v[/tex] (2)
Let suppose that given vector velocity is expressed in meters per second. If we know that [tex]m = 2\,kg[/tex], [tex]\vec v = (2\cdot t, 4\cdot t^{2})\,\left[\frac{m}{s} \right][/tex] and [tex]t = 2\,s[/tex], then the force acting on the object is:
[tex]\vec a = (2, 8\cdot t)\,\left[\frac{m}{s^{2}} \right][/tex]
[tex]\vec F = (4, 16\cdot t)\,[N][/tex]
[tex]\vec F = (4, 32)\,[N][/tex]
The force acting on the object at [tex]t = 2\,s[/tex] is [tex]\vec F = (4, 32)\,[N][/tex].

A voltage is applied to a resistor,
which creates a 1.50 A current. If
you double the resistance, keeping
the voltage the same, what will the
new current be?
(Unit = A)
Answer:
Explanation:
By Ohms Law, Voltage = Current * Resistance
Keeping the voltage the same and doubling the resistance, the current will be halved.
So the new current = 1.5/2 = 0.75A
By using Ohms law, the current will be 0.75A.
What is Ohm's law?Ohm's law states that the current flowing through a resistance is proportional to potential difference across the resistance under constant temperature and pressure conditions. Ohm's law can be expressed as:
V =IR
Here, I = 1.50 AR = R Ωso, V = 1.50 R Now Voltage is same but resistance is doubled so new resistance is
Now, put the values of given data in ohms law formula:
2RI = 1.50 R/ 2R = 0.75A
Hence current is 0.75A

The cheetah is one of the fastest-accelerating animals, because it can go from rest to 27 m/s (about 60 mi/h) in 4.0 s. If its mass is 110 kg, determine the average power developed by the cheetah during the acceleration phase of its motion. Express your answer in
(a) watts
(b) horsepower.
Answer:
A. 10023.75 Watts
B. 13.44 horse power
Explanation:
A. Determination of the power in Watts.
We'll begin by calculating the energy of the cheetah. This can be obtained as follow
Velocity (v) = 27 m/s
Mass (m) = 110 kg
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 110 × 27²
KE = 55 × 729
KE = 40095 J
Finally, we shall determine the power in Watts. This can be obtained as follow:
Kinetic energy (KE) = 40095 J
Time (t) = 4 s
Power (P) =?
Power = Energy /time
Power = 40095 / 4
Power = 10023.75 Watts
B. Determination of the power in horse power.
Power in Watts = 10023.75 Watts
Power in horse power =?
Recall:
746 Watts = 1 hp
Therefore,
10023.75 Watts = 10023.75 / 746
10023.75 Watts = 13.44 hp
Therefore, the power in horse power is 13.44 hp
