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.

Sadie wants to sell her fan-fiction on the online platform Fanalot. Instead of selling a subscription plan to all of the stories she has written, she decides to sell readers access to each story individually. Her online research suggests that if she charges x dollars per story, she will sell – 5x+100 stories per month. Fanalot will charge Sadie 20% of the amount she charges per story. So, Sadie will earn 80% of the amount she charges per story, or 0.8x dollars, in profit. Which equation can Sadie use to estimate the price she can charge per story to earn $300 in profit each month?
Answers
0.8x(5x+100) - 0.2x(5x+100) = 300
Simplifying this equation, we get:
4x^2 + 80x - 300 = 0
This is a quadratic equation that can be solved using the quadratic formula:
x = (-b ± sqrt(b^2 - 4ac)) / 2a
Plugging in the values for a, b, and c, we get:
x = (-80 ± sqrt(80^2 - 4(4)(-300))) / 8
x = (-80 ± sqrt(73600)) / 8
x = (-80 ± 271.23) / 8
x = -43.9 or 7.9
Sadie cannot charge a negative price, so the only possible solution is:
x = 7.9
Therefore, Sadie can charge $7.90 per story to earn $300 in profit each month.

A bicycle with 540mm wheel diameter passes over a segment arched culvert of radius 760mm. draw the locus of a point on the circumference of the wheel when it makes one complete revolution
Answers
In order to draw the locus, we can construct a circle with a radius of 1696.62mm centered at the center of the culvert.
How to calculate the valueThe diameter of the wheel is given as 540mm, so the radius of the wheel is half of that: 540mm / 2 = 270mm. The circumference of the wheel can be calculated as 2π times the radius: 2π × 270mm
≈ 1696.62mm.
Since the circumference of the wheel is approximately 1696.62mm and point P traces out a circle, the locus of point P will be a circle with a circumference of 1696.62mm.
Hence, to draw the locus, we can construct a circle with a radius of 1696.62mm centered at the center of the culvert.

Question 4 (15 pts) Suppose you are part of a team who is working on developing an artificial respiratory device for patients. At some point, you needed to estimate the power required for the inhalation of an average person. Using your fluid mechanics knowledge and with some additional assumptions, you should be able to determine. It is known that the tidal volume, which is the air breathed in with each normal breath through the mouth and nose (labeled as A), is 0.5 liters. If it occurs within 1.5 seconds through the trachea (labeled as B) having a cross-sectional area of 125 mm2 , estimate the power required for a single inhalation. State any assumptions you are making. Hint: Recall that Power=(Force, F) x (velocity, v)
Answers
Where the above conditions are ogiven, the power required for a single inhalation is approximately 0.00141 W.
What is the explanation for the above response?To estimate the power required for a single inhalation, we need to calculate the force and velocity of the air flowing through the trachea.
Assumptions:
We assume that the air can be treated as an incompressible fluid.
We assume that the air flow is laminar.
We assume that the trachea is a straight pipe with a constant diameter of 10 mm (since the cross-sectional area is 125 mm^2).
We neglect any frictional losses due to the presence of the walls of the trachea.
First, let's calculate the velocity of the air. We know that the tidal volume is 0.5 liters, which is equivalent to 500 ml or 0.0005 m^3. This volume is breathed in within 1.5 seconds, so the flow rate of air through the trachea is:
Q = V/t = 0.0005 m^3 / 1.5 s = 0.000333 m^3/s
The cross-sectional area of the trachea is 125 mm^2, which is equivalent to 0.000125 m^2. Using the continuity equation for incompressible fluids, we can relate the flow rate of air to its velocity:
Q = A x v
where A is the cross-sectional area of the trachea and v is the velocity of the air. Solving for v, we get:
v = Q/A = 0.000333 m^3/s / 0.000125 m^2 = 2.664 m/s
Now that we have the velocity, we can calculate the force of the air using the equation:
F = ρ x A x v^2 / 2
where ρ is the density of air, which we can assume to be 1.2 kg/m^3 (at standard conditions of temperature and pressure). Substituting the values, we get:
F = 1.2 kg/m^3 x 0.000125 m^2 x (2.664 m/s)^2 / 2 = 0.000530 N
Finally, we can calculate the power required for a single inhalation using the equation:
Power = Force x Velocity
Substituting the values, we get:
Power = 0.000530 N x 2.664 m/s = 0.00141 W
Therefore, the power required for a single inhalation is approximately 0.00141 W.

Answer:
The correct option is;
A. Decrease or eliminate fossil fuel consumption
Explanation:
Eco-driving is the perceptive and present day method of driving that focuses on safety, fuel efficiency, swift journey to a destination.
Eco-driving lay emphasis on fuel economy as consuming fuel and or other forms of energy is expensive and has long term disastrous effect on the environment by contributing to global warming
The goal of Eco-driving can be achieved by ensuring to put safety first while applying the following rules;
1) Traffic flow anticipation
2) Avoiding high RPM and maintenance of a constant driving speed
3) Change to a higher gear early
4) Ensure tyres are in good condition before high speed driving

Which type of stress does an object experience when twisted from one end?
While twisting an object from one end, it experiences
stress.
Answers
Answer:
Torsional stress.
Explanation:
An item experiences torsional tension when it is twisted from one end. The molecules on an item's surface are tugged in various directions as the object is twisted, creating a twisting force or torque. As a result, the item experiences what is known as torsional stress. It is a kind of shear stress that has an impact on the material along the object's axis. The stiffness and strength of a material determine how much torsional stress an item can bear.
