The three product which can be potentially fail considering Load Strength graph and precautionary measure to prevent failure are as below;

Ball Pen:

1. Ink Leakage: One potential failure of a ball pen is ink leakage. This can occur due to poor sealing between the ink reservoir and the ballpoint mechanism. Ink leakage can result in messy hands, stained documents, and reduced functionality of the pen. To prevent this failure, manufacturers can improve the quality control process to ensure proper sealing and use high-quality materials for the pen's components.

2. Ballpoint Jamming: Another failure is ballpoint jamming, where the ball gets stuck and prevents smooth writing. This can be caused by a buildup of dried ink or debris inside the pen's mechanism. To prevent ballpoint jamming, regular cleaning and maintenance of the pen can be recommended. Additionally, manufacturers can design the pen with features that facilitate easy cleaning or provide instructions on how to clear any blockages.

3. Weak Barrel Construction: The barrel of the pen may also be prone to failure if it is weak or brittle. Excessive pressure or rough handling can lead to cracks or breakage, rendering the pen unusable. To prevent this, manufacturers can use durable materials for the pen barrel, such as sturdy plastics or reinforced metal, and perform quality checks to ensure structural integrity.

Room Key:

1. Keycard Malfunction: A potential failure of a room key is a malfunction in its electronic components. This can result in the keycard being unreadable by the door lock system, preventing access to the room. To prevent this failure, regular maintenance and replacement of keycard readers can be implemented. Additionally, guests should be advised to keep their keycards away from magnets and electronic devices that can interfere with the card's functionality.

2. Magnetic Strip Damage: Another failure can occur if the magnetic strip on the keycard gets damaged or demagnetized. This can happen due to exposure to magnetic fields or physical damage. To prevent this failure, keycards can be made more durable with protective coatings or alternative technologies such as RFID. Guests should also be educated on proper handling and storage of keycards to avoid damage.

3. Battery Drain: Some room keys use batteries to power their electronic components. A failure can occur if the battery drains, leading to an inactive keycard. To prevent this, low-power consumption designs can be implemented, and regular battery checks or replacements can be carried out by hotel staff. Guests should be informed about the importance of returning the keycard to the front desk for recycling or proper disposal to ensure the battery is replaced as needed.

Blender:

1. Motor Burnout: One potential failure of a blender is motor burnout due to prolonged use or overloading. Continuous operation at high speeds or attempting to blend hard or frozen ingredients beyond the blender's capacity can cause the motor to overheat and fail. To prevent motor burnout, manufacturers can provide clear guidelines on the maximum load capacity and recommended usage durations. Automatic thermal protection mechanisms can also be incorporated to shut off the blender if it detects excessive heat.

2. Blade Jamming: Another failure can occur if food particles or ingredients get jammed between the blender's blades, preventing them from spinning freely. This can happen if the blender is not properly cleaned or if ingredients are not adequately prepared before blending. To prevent blade jamming, users should be advised to clean the blender thoroughly after each use and ensure that ingredients are cut into manageable sizes. Manufacturers can also design blades with accessible mechanisms for easy cleaning or provide cleaning tools.

3. Leakage: A failure in a blender can also manifest as leakage. This can happen if the blender jar or its sealing components are damaged or improperly assembled. Liquid or food can leak out during blending, resulting in a messy and potentially unsafe situation. To prevent leakage, manufacturers should ensure proper sealing mechanisms and use high-quality materials for the blender jar and lid. Regular inspection of the sealing components can be advised,

The height of the building using second equation of motion is 35.721 m

What is the second equation of motion?

In kinematics, equations of motion are referred to as the fundamental principles of an object's motion, including velocity, location, and acceleration that occur at variable time intervals. These three motion equations control motion in all three dimensions of an item.

Second equation of motion: s = ut +  a(t^2)/2

where,

s = displacement

u = initial velocity

v = final velocity

a = acceleration

t = time of motion

Given, a = 9.8 m/s/s

           t = 2.7 s

Using this equation we find the height of the building,

s = ut +  a(t^2)/2

  = 0 + 9.8 x 2.7 x 2.7/2

  = 71.442/2

  = 35.721 m

Hence, the height of the building is 35.721 m

The relative velocity of object 1 with respect to object 2 will be → +5 mph along the positive y - axis.

We have two objects moving in north direction.

We have to determine the relative velocity of object 1 relative to object 2.

The velocity of an object A relative to another object B is the velocity that object A would appear to have to an observer moving with B.

According to the question, we have -

The velocity of Object 1 = v(1) = \(10\;a_{y}\) mph

The velocity of Object 2 = v(2) = \(5\;a_{y}\) mph

Since the two objects 1 and 2 are moving in the same direction, therefore the velocity of object 1 relative to object 2 will be -

v(1)' = v(1) - v(2) =  \(10\;a_{y}\)  -  \(5\;a_{y}\) =  \(5\;a_{y}\) mph

Hence, the relative velocity of object 1 with respect to object 2 will be → +5 mph along the positive y - axis.

The coefficient of friction depends on both the mass of the objects and the material make-up of the surfaces in contact.

The coefficient of friction is a dimensionless quantity that represents the ratio of the force of friction between two surfaces to the normal force pressing them together. It is denoted by the symbol "μ."

The coefficient of friction is influenced by several factors, including the mass of the objects involved and the material properties of the surfaces in contact. The mass affects the normal force, which is directly proportional to the weight of an object. As the mass increases, the normal force and, subsequently, the frictional force also increase.

The material make-up of the surfaces is another crucial factor. Different materials have different surface textures, roughness, and chemical properties that affect the frictional interaction between them. For example, a rough surface will generally have a higher coefficient of friction compared to a smooth surface.

Therefore, the coefficient of friction depends on both the mass of the objects and the material make-up of the surfaces. These factors play a significant role in determining the frictional forces acting between objects in contact.

the provided options (a. 2, b. 0.5, c. none, d. 0.25) matches the correct answer. To determine the gain of the tachometer, we can use the reciprocal of the transfer function of the motor.

which represents the relationship between the output (angular speed) and the input (voltage).

The given transfer function for the motor is:

H(s) = 2 / (0.15s + 1)

To convert the motor into a tachometer, we need to find the reciprocal of this transfer function. In other words, we invert the numerator and denominator:

H_tachometer(s) = (0.15s + 1) / 2

The gain (KT) of the tachometer is the coefficient in front of the s term in the numerator. From the equation above, we can see that the coefficient is 0.15. Therefore, the gain of the tachometer is 0.15 V/(rad/s).

We are talking about motion of solid, liquid and gas particles.

Now, for gas particles, due to the fact that it's particles are far apart from one another, it usually vibrates and thus moves freely at speeds that are higher than those of liquids of solids. For liquids, their particles are not as far apart as those of gases and so they vibrate, move about, and then slide past each other while solids are the most densely packed and so they vibrate but do not move from one place to the other like gases and liquids.

Thus, we can see that particles of liquid are more closely packed than gases and as such don't have same movement speed.

Based on current data, it is estimated that about 20-25% of stars have at least one planet orbiting them within the habitable zone, where conditions could support life as we know it. However, the fraction of stars with planets increases to about 50% when considering all planets, including those outside the habitable zone.

These estimates come from data collected by NASA's Kepler spacecraft, which searched for planets by observing the periodic dimming of stars as planets pass in front of them. In addition to Kepler, other telescopes and methods have also been used to detect exoplanets, which has greatly expanded our understanding of planetary systems beyond our own solar system.

However, it is important to note that these estimates are constantly changing as new data is collected and analyzed. As technology improves, we may be able to detect even more planets and better understand their distribution around other stars.

The speed of light (c) in air is 2.99792 × 10^8 m/s, and the wavelength of visible light (λ) is 5 × 10^-7 m.

We can use the formula for the speed of light, which is:

c = λν

where ν is the frequency of the light wave.

Solving for ν, we get:

ν = c / λ

Substituting the values we have:

ν = (2.99792 × 10^8 m/s) / (5 × 10^-7 m)

ν = 5.99584 × 10^14 Hz

Therefore, the frequency of the light wave is approximately 5.99584 × 10^14 Hz.

The efficiency of the system, consisting of a 3-ohm heater submerged in 1200 grams of water, is approximately 101.2% based on the given information.

To determine the efficiency of the system, we need to calculate the energy input and the energy output.

The energy input is given by the formula:  Energy input = Voltage × Current × Time

Since the heater has a resistance of 3 ohms and operates at 6 amperes for 3.95 hours, we can calculate the energy input as follows:

Energy input = (Voltage × Current) × Time = (Voltage² / Resistance) × Time

Given that the voltage is unknown, we need to solve for it. We can use Ohm's law to find the voltage: Voltage = Current × Resistance = 6 A × 3 Ω = 18 V

Now we can calculate the energy input: Energy input = (18² / 3) × 3.95 = 381.6 Joules The energy output can be calculated using the specific heat capacity of water and the change in temperature: Energy output = (Mass of water + Water equivalent) × Specific heat capacity × Change in temperature

Given that the mass of water is 1200 grams, the water equivalent is 200 grams, the specific heat capacity of water is approximately 4.18 J/g°C, and the change in temperature is 70°C, we can calculate the energy output: Energy output = (1200 + 200) × 4.18 × 70 = 386,360 Joules

Finally, we can calculate the efficiency of the system: Efficiency = (Energy output / Energy input) × 100 Efficiency = (386,360 / 381.6) × 100 ≈ 101.2% Therefore, the efficiency of the system is approximately 101.2%.
