Explanation:

A. Another conclusion that can be drawn from the student experiment is the ball stops because there is some force acting on it.

There are several forces that will act on an object moving on an inclined plane. These forces include the following;

When the object is moving up, gravitational force will tend to pull the object downwards and the frictional force will tend to oppose this downward motion of the object.

When the object is rolled down the plane, gravitational force tends to aid the motion of the object while frictional force tends to slow the object down.

Eventually, the object stops because the frictional force opposing the object motion is greater than the gravitational force pushing the object downwards.

Thus, another conclusion that can be drawn from the student experiment is the ball stops because there is some force acting on it.

The correct answer to your question is a. interposition. Interposition is a cue used by artists to convey depth on a flat canvas. In this technique, artists place objects in front of one another to create the illusion of depth and distance. This method helps to suggest that some objects are closer to the viewer, while others are further away

One of the cues that artists use to convey depth on a flat canvas is interposition. This refers to objects in the foreground overlapping those in the background, creating a sense of depth and distance. Other cues that artists may use include proximity, which is the placement of objects in relation to each other, and continuity, which refers to the smooth flow of lines and shapes. Closure, on the other hand, is the ability of the viewer to mentally complete incomplete shapes or patterns, and is not necessarily related to depth perception. Overall, artists use a variety of techniques and cues to create the illusion of depth on a two-dimensional canvas, and these skills are essential to creating engaging and realistic works of art.

Answer:

1.

Distance = 0.921 meters

2.

Work = 13.9 kJ

3.

The neighbor

Double your work

Explanation:

1.

Work = Force × Distance

Distance = Work / Force

Distance = 174J /189 N

Distance = 0.921 meters

2.

Work = force × distance

Work = (613 N) (22.6 m)

Work = 13,900 J

Work = 13.9 kJ

3.

Work is a product of force and distance, expressed as W=Fd where W is work in Nm, F is applied force and d is the distance in m

Since your neighbor pushes 4 times then you just push 1m when he pushes 4m, that is an example. Also, since the neighbor only exerts half the force i.e. 0.5N then you exert full force of 1N

Work from your neighbor will be 4d*0.5F=2dF

Work from you will be dF

Clearly, 2dF=2(dF) hence the neighbor exerts double work

Answer:

True

Explanation:

Displacement can be considered as a distance with direction when an object moves in straight line. Distance is a scalar quantity which means it has only magnitude but lack of direction. Magnitude basically means how far or how long from the initial startup (e.g 7 km) is magnitude.

On the other hand, displacement is a vector quantity which means it has both magnitude and direction. We can use a symbol of negative and positive to determine the direction. Generally, up is positive; down is negative; west is negative and east is positive but it depends on some case where down can be positive (e.g projectile motion) but you can specify or modify how you want your direction to be, make sure to calculate it right though.

Displacement means changes in position which can be expressed as \(\displaystyle{p_2 -p_1}\) where \(\displaystyle{p_2}\) is final position/destination and \(\displaystyle{p_1}\) is initial position/destination. Displacement does include distance but maybe not total distance if we go for a right-triangle distance. However, displacement includes total distance if an object moves in a straight point. (e.g moving to 20 km straight) - both distance and displacement are same in this case.

The star is located at a distance of 31.62 parsecs from us.

To determine the distance of the star, we need to use the inverse square law, which states that the apparent brightness of a star decreases as the square of its distance increases. Mathematically, it can be represented as:
Apparent brightness ∝ 1/Distance²
Given that the star's apparent brightness is 10⁻⁴ times its absolute brightness, we can write:
Apparent brightness = Absolute brightness/ (Distance)²
10⁻⁴ = Absolute brightness/ (Distance)²
Solving for distance, we get:
Distance = √(Absolute brightness/10⁻⁴)
However, we don't have the value of absolute brightness. But we can use the information that the star is observed to have an apparent magnitude of 10. Since apparent magnitude is a logarithmic scale, we know that a difference of 5 magnitudes corresponds to a difference of 100 times in brightness. Therefore, the star's absolute magnitude can be calculated as:
Absolute magnitude = Apparent magnitude - 5 log(distance/10)
Substituting the values, we get:
10 = Absolute magnitude - 5 log(distance/10)
Absolute magnitude = 10 + 5 log(10⁻⁴) = 14
Therefore, the distance can be calculated as:
Distance = 10^(1+((Apparent magnitude - Absolute magnitude)/5))
= 10^(1+((10 - 14)/5))
= 31.62 parsecs
Thus, the star is located at a distance of 31.62 parsecs from us.

Question:

A block of mass 1kg is placed on an inclined plane at an angle of 30° to the horizontal. Calculate the frictional force, normal reaction, the coefficient of the static friction​

Answer:

Break the mg force into components in the plane of the inclined plank. Now force acting parallel is mgsin37°. Perpendicular force is mgcos37° which is equal to normal force.  

Now calculate max value of friction force which is 0.8*mg cos37°. Since its greater than pulling force mgsin37°, the body will be at rest and acceleration is zero.  

Force applied by surface is vector sum of normal force and friction force acting.

Answer:

a) F = 5.14 10⁻⁸ Hz,  f = 4.76 10-8 Hz,  b)   v = 2.29 m / s,   f = 42.5 Hz

Explanation:

a)This problem has two parts.

For the calculations relative to the planet Venus, we use that the period and the frequency are related

            f = 1 / T

frequency of the orbit around the Sun

Let's reduce the period to the SI system

           T = 225 days (24h / 1days) (3600 s / 1h) = 1.94 10⁷ s

           F = 1 / 1.94 10⁷

           F = 5.14 10⁻⁸ Hz

rotation frequency

            T = 243 d = 2.1 107 s

             f = 1 / T

             f = 1 / 2.1 107

            f = 4.76 10-8 Hz

b) give the data of some marine waves

the speed of the wave can be found with kinematics

            v = x / t

            v = 50.0 / 21.8

            v = 2.29 m / s

If the wavelength is L = 9.28m

this distance is the distance between two consecutive ridges or valleys

             λ / 2 = L

             λ = 2L

             λ = 2 9.28

             λ = 18.56 m

the speed of the wave is

             v = λ f

             f = v /λ

             f = 2.29 / 18.56

             f = 42.5 Hz

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,
