The ________________ attraction between the Earth and the moon is ______________ on the side of the Earth that happens to be ____________ the moon, simply because it is ________. This attraction causes the water on this “_________” of Earth to be pulled ___________ the moon.
Answer:
Gravitational; strongest; facing; closer; near side; toward.
Explanation:
The gravitational attraction between the Earth and the moon is strongest on the side of the Earth that happens to be facing the moon, simply because it is closer. This attraction causes the water on this “near side” of Earth to be pulled toward the moon. These forces of attraction and inertia tends to keep the water in place and consequently, leads to a bulge of water on the near side with respect to the moon.
Also, you should note that what is responsible for the moon being in orbit around the Earth is the gravitational force of attraction between the two planetary bodies (Earth and Moon).

Which option identifies what process should be used as a model for design in the following scenario?
John is developing a handheld camera, unlike any others that have been developed before. Even though he understands what the final product will be, it still requires further development and modification.
A. engineering design process
B. reverse engineering process
C. structural process
D. brainstorming process
Answer:
A. engineering design process
Explanation:
We are told that John is trying to develop a handheld camera. And that it is unlike any other one that has been developed before.
Now, though he understands what the final product will look like, the camera still required further development and modification. This is simply an engineering design process because it involves finding a need and trying to solve it since he already understands what the final product will be.
Why are the main cables of the Golden Gate Bridge made of numerous smaller cables?
Answer:
The main cables of the Golden Gate Bridge are made of numerous smaller cables because by combining several thousand in number of smaller cables, each having a diameter which is approximately the diameter of a pencil, into the required cable diameter dimensions, the flexibility, strength, resistance to cracking, rotation resistance, crushing resistance and fatigue resistance of the main cables are increased, and failure of a few strands in a multi-stranded cable is more likely to be detected before catastrophic failure takes place than in a single cable
The properties of strength and flexibility that the cable provides are required so that the bridge can better cushion the seismic turbulence of the water and strong wind energy at the bay of San Francisco, the location of the bridge

A gear train has a ratio of 40/24 and the driving gear is turning 100 RPM.
What is the speed of the driven gear in RPM?
Answer:
S2 = 60 RPM.
Explanation:
Given the following data;
Gear ratio = 40/24 (T2 = 40 and T1 = 24).
Speed of driving gear = 100 RPM
To find the speed of the driven gear;
Mathematically, gear ratio in terms of speed (RPM) is given by this formula;
[tex] S_{1} * T_{1} = S_{2} * T_{2} [/tex]
Where;
S1 represents the speed of the driver gear.S2 represents the speed of the driven gear.T1 represents the number of teeth of the driver gear.T2 represents the number of teeth of the driven gear.Substituting into the equation, we have;
[tex] 100 * 24 = S_{2} * 40[/tex]
[tex] 2400 = 40S_{2} [/tex]
[tex] S2 = \frac {2400}{40} [/tex]
S2 = 60 RPM.
Therefore, the speed of the driven gear is 60 revolutions per minute.

10) A roller coaster has a circular loop of radius 5.0 m. You go around at the minimum speed.
How fast will you be moving at the bottom?
What is your acceleration? (in m/s2, in g’s)
How does this feel? Where else have you felt this effect?
Draw a Force Diagram at the bottom.
This is dangerous. What should the radius be at the bottom, so that you only feel 2 g’s?
.
Explain why these loops have the shape that they do.
Answer:
1) The speed of the roller coaster at the bottom is approximately 15.65 m/s
2) The acceleration of the roller coaster at the bottom is 6·g's
3) The high acceleration is 6 times the force of the weight of the passengers
The high acceleration can cause gravity induced loss of consciousness
4) Please find attached a force diagram of the forces at the bottom of the roller coaster created with Microsoft Visio
5) For the acceleration at the bottom to be 2·g's the radius of the rollercoaster at the bottom should be 25 meters
5) The radius at the bottom of roller coasters are increased to reduce the normal force felt by the passengers as they pass the bottom of a circular roller coaster
Explanation:
1) The given parameters are;
The radius of the roller coaster, r = 5.0 m
The speed of the roller coaster = Minimum = 0 m/s
The shape of the roller coaster's path = Circular loop
Therefore, the maximum height of the roller coaster, h = The diameter of the of a circular path of the roller coaster, d = 2 × r = 2 × 5.0 m = 10.0 m
∴ h = 10.0 m
The minimum speed is f=given by the following equation;
[tex]F_N = \dfrac{m \cdot v^2}{R} - m \cdot g = 0 \ (At \ the \ top \ of \ the \ roller \ coaster's \ path)[/tex]
Therefore, we have;
[tex]\dfrac{m \cdot v^2}{R} = m \cdot g[/tex]
From which we have;
v = √(R × g)
Where;
R = The radius of the path of the roller coaster = 5.0 m
g = The acceleration due to gravity = 9.8 m/s² = constant
By plugging in the values of the variable, 'R', and the constant, 'g', we get;
v = √(5.0 m × 9.8 m/s²) = 7 m/s
The minimum speed of the roller coaster, v = 7 m/s
The speed of the roller coaster at the bottom is given by the conservation of energy formula as follows;
The energy at the top of the roller coaster = The energy at the bottom of the roller coaster
∴ The total mechanical energy of the roller coaster, M.E., is constant and at the top, [tex]M.E._{top}[/tex], is given as follows;
[tex]M.E._{top}[/tex] = 1/2·m·v₁² + m·g·h₁
At the bottom, the total mechanical energy is given as follows;
[tex]M.E._{bottom}[/tex] = 1/2·m·v₂² + m·g·h₂
Where;
v₁ = The velocity of the roller coaster at the top = 7 m/s
h₁ = The height of the roller coaster at the top = 10 m
v₂ = The speed of the roller coaster at the bottom
h₂ = The height of the roller coaster at the bottom = 0 m
g = The acceleration due to gravity = 9.8 m/s² = Constant
By plugging in the values, we get;
M.E. = [tex]M.E._{top}[/tex] = [tex]M.E._{bottom}[/tex]
∴ 1/2·m·v₁² + m·g·h₁ = 1/2·m·v₂² + m·g·h₂
1/2 × (7 m/s)² + 9.8 m/s² × 10.0 m = 1/2 × v₂² + 9.8 m/s² × 0 m
122.5 m²/s² = 1/2 × v₂²
∴ v₂² = 2 × 122.5 m²/s² = 245 m²/s²
v₂ = √(245 m²/s²) = 7·√5 m/s ≈ 15.65 m/s
The speed of the roller coaster at the bottom, v₂ ≈ 15.65 m/s
2) The normal force on the car at the bottom of the roller coaster is given as follows;
[tex]F_N = \dfrac{m \cdot v_2^2}{R} + m \cdot g = m \times \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
Force, F = Mass, m × Acceleration, a
∴ F = m×a
Therefore, the acceleration at the bottom, 'a' by comparison of the general equation for force, 'F', and the normal force, [tex]F_N[/tex], is given as follows;
[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
Plugging in the values for 'v₂²', 'R', ang 'g', gives;
[tex]a = \left(\dfrac{ v_2^2}{R} + g \right ) = \left(\dfrac{ 245}{5} + 9.8 \right ) = \left(49+ 9.8 \right ) = (5 + 1) \times 9.8 = 6 \times 9.8 = 6 \times g[/tex]
a = 6·g = 58.8 m/s²
3) The high acceleration will lead to a very high normal force (equal to 6 times each of their weight) experienced by the passengers with a force
The high acceleration is dangerous and can lead to gravity induced loss of consciousness since it is more than 3·g's
4) Please find attached the force diagram at the bottom of the roller coaster created with Microsoft Visio
5) For the acceleration at the bottom to be 2·g's, we have;
[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
At a = 2·g, we have;
[tex]2 \cdot g = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
[tex]\therefore 2 \cdot g - g = g = \dfrac{ v_2^2}{R}[/tex]
[tex]R = \dfrac{ v_2^2}{g} = \dfrac{245}{9.8} = 25[/tex]
R = 25 m
The radius at the bottom of the roller coaster should be 25 meters so that only 2·g's is felt
5) The shape of the roller coaster has an increases the radius at the bottom so as to reduce the acceleration of the car

Question # 7
Long Text (essay)
In paragraph of 125 words, explain at least three ways that engineers explore possible solutions in their projects
Answer:
To do this, engineers often use a technique called "brainstorming." Brainstorming is a team creativity activity that helps you generate a large number of potential solutions to a problem or challenge.
Engineers use the engineering design process when brainstorming solutions to real-life problems; they develop these solutions by testing and redesigning prototypes that work within given constraints.
Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work.

How much salt will one teaspoon of water dissolve? Complete this experiment to find out!
Materials:
salt
a small glass jar with a lid
water
measuring spoons
Follow these steps:
Carefully measure out 3 Tablespoons of cold water into the jar.
Now measure out 1/8 teaspoon of salt and put it into the jar with the water. Put the lid on the container and shake it. Keep shaking until the salt is completely dissolved. To determine whether it has completely dissolved, hold the container up to the light and look carefully at the bottom, or open the lid and look into it. If you see little grains of salt there, it is not completely dissolved, so keep shaking until it looks the same each time you look.
If the salt does not dissolve completely after five minutes of vigorous shaking, write this in your notebook and go on to step 4. If the salt dissolves completely, add another 1/8 teaspoon of salt and repeat the process. Repeat over and over, keeping track of how many 1/8 teaspoons you add. Stop when you can’t get the salt to dissolve no matter how hard or long you shake the container.
Record how much salt you were able to dissolve in the 3 Tablespoons of water in the solubility data table.
Repeat steps 1-4, but this time using very warm or hot water. Before you do it, run the jar under hot water to warm it up so the water doesn’t cool off right away. Be sure to use the exact same amounts of water and salt as you did the first time. The only variable should be the temperature of the water.
Record your results, and then compare with your previous results.
Answer the following questions:
Were there any differences in the amount of salt that dissolved in the warm water versus the cold water?
Write a conclusion based on your results, using the terms “temperature” and “solubility.”
Based on your results, answer this question: If the oceans of the earth got warmer from global warming, would the water of the oceans become more or less salty? What do you think the effect of this change in the ocean salinity (saltiness) would be on the plants and animals that live in the ocean?
