4. Tony Hawk weighs about 60 kg. Calculate the difference in the pressure placed on the snow if he was standing in the snow on one snowshoe compared to standing in the snow in one boot. The area of the snowshoe is 0.20 m² and the area of the boot is 0.05 m².
Answers
The difference in pressure placed on the snow when Tony Hawk stands on one snowshoe compared to standing in one boot is 800 Pa.
1. Convert the weight of Tony Hawk from kg to N (Newton):
Weight = Mass x Gravity
Given that Tony Hawk weighs about 60 kg and the acceleration due to gravity is approximately 9.8 m/s²,
Weight = 60 kg x 9.8 m/s² = 588 N
2. Calculate the pressure exerted by Tony Hawk on the snow when standing on one snowshoe:
Pressure = Force / Area
Given that the area of the snowshoe is 0.20 m²,
Pressure on snowshoe = 588 N / 0.20 m² = 2940 Pa
3. Calculate the pressure exerted by Tony Hawk on the snow when standing in one boot:
Given that the area of the boot is 0.05 m²,
Pressure on boot = 588 N / 0.05 m² = 11760 Pa
4. Calculate the difference in pressure placed on the snow:
Difference in pressure = Pressure on snowshoe - Pressure on boot
Difference in pressure = 2940 Pa - 11760 Pa = -8820 Pa
Note: The negative sign indicates that the pressure on the snowshoe is lower compared to the pressure on the boot. However, in this context, the absolute value of the difference (8820 Pa) represents the magnitude of the pressure difference.

3: Control group: The ___ that is given either a standard of treatment or ____
Example #1 Example #2.
Answers
It is unnecessary to formulate a hypothesis in answering a question based solely on observing or collecting data, as opposed to conducting a complete scientific experiment.
How is experimentation done?On the other hand, determining an answer through experimentation involves analyzing variables and establishing a clear cause-and-effect relationship using the scientific method.
A control group is defined as a test group that receives standard treatment or a placebo, which serves as a basis of comparison for the experimental group.
For instance, one trial compared high blood pressure medication with a placebo given to patients experiencing hypertension. While the course of action was administered to some participants, those assigned to the control group were instead given a placebo.
Similarly, in a different study aimed at studying plant growth, certain plants received a new fertilizer while others were exposed to a standard fertilizer, serving as a component of this analysis's control group.

Specific Fuel Consumption (SFC) is more favorable as a low value, which is the inverse of an automobile mileage efficiency value. Why is this?
Answers
The term "specific fuel consumption," or SFC, compares the amount of gasoline an engine uses to a particular force, like the amount of power it generates.
What is specific fuel ?
It enables comparisons between engines of various sizes to determine which is the most fuel-efficient. It enables manufacturers to identify the engine that will consume the least amount of gasoline while yet generating a lot of power.
SFC can take many different forms, but two of the most popular are TSFC (thrust specific fuel consumption) and BSFC (brake specific fuel consumption). According to TSFC, fuel consumption of an engine is compared to the engine's power or thrust production.
For instance, it is possible to analyze different airplane engines to determine which will deliver the highest thrust while consuming the least gasoline.

50 POINTS! - How to find scale of a design to real life?
(QUESTION EXPLANATION/CONTEXT)
So I have a culminating project and we need to make a 3D model of a bus shelter. My bus shelter is 14 inches high in the 3D modelling editor and supposed to be 157 inches in real life. I need the scale for that size. I am not sure how to find it. If you need any additional info about the design, just comment and I'll send it. ty!
Answers
To find the scale of your 3D model in relation to real life, you can use the following formula:
Scale = Real Life Size / Model Size
In your case, the real-life size of the bus shelter is given as 157 inches, and the model size is 14 inches. Plugging these values into the formula:
Scale = 157 inches / 14 inches
Scale ≈ 11.21
Therefore, the scale of your 3D model would be approximately 1:11.21. This means that one unit in your 3D model represents 11.21 units in real life. To convert any measurements from your 3D model to real-life measurements, you would multiply them by the scale factor.
