The producer of refrigerator compressors needs to determine the number of kanbans required for implementing a just-in-time production line to meet the demand for 150 compressors per day from a neighboring appliance manufacturer.

To calculate the number of kanbans required, we need to consider the production lead time, safety stock factor, and optimal production quantity. The production lead time is 5 days, which means that it takes 5 days to produce a batch of compressors once the production process starts.

The safety stock factor is 17%, indicating that the producer wants to maintain an additional 17% of the daily demand as safety stock to mitigate any unforeseen fluctuations. The optimal production quantity is 95 units, which is the batch size that minimizes setup costs.

To determine the number of kanbans, we first need to calculate the total demand during the production lead time. Since the demand is 150 compressors per day and the lead time is 5 days, the total demand during the lead time is 150 compressors/day * 5 days = 750 compressors. Adding the safety stock, the total demand becomes 750 compressors + (17% * 150 compressors) = 750 compressors + 25.5 compressors = 775.5 compressors.

Next, we divide the total demand by the optimal production quantity to get the number of kanbans required. The number of kanbans is calculated as 775.5 compressors / 95 compressors per kanban = 8.16 kanbans. Since we cannot have a fraction of a kanban, we round up to the nearest whole number. Therefore, the producer of compressors requires 9 kanbans to meet the demand of 150 compressors per day from the neighboring appliance manufacturer.

Answer:

To holds the legs apart without rupturing any vein

Explanation:

The purpose of using string to tie the forelegs and hind legs during dissection is to hold the legs apart without rupturing ant vein or artillery for easy dissection procedure( the dismembering of the body of a deceased animal or plant to study its anatomical structure)

when tieing the forelegs and the hind legs the same string is used to tie them and the string is then passed/looped under the dissecting table/tray this way the legs will be held apart and the dissection can commence.

Answer:

The correct option is;

πR³(2/3 + (1/3)cos³θ - cosθ)

Explanation:

The volume of a segment of a sphere is given by the relation;

\(V = \pi \cdot h^2 \cdot \left (R - \dfrac{h}{3} \right)\)

We note that h = R - R·cos(θ)

Therefore by substituting the value of h in the equation of a segment of a sphere, we have;

\(V = \pi \cdot \left (R - R\cdot cos(\theta) \right ) ^2 \cdot \left (R - \dfrac{\left (R - R\cdot cos(\theta) \right )}{3} \right)\)

Which gives;

\(\dfrac{R^3\cdot \pi \cdot cos^3 (\theta) -3 \cdot R^3 \cdot\pi \cdot cos (\theta) + 2 \cdot R^3 \cdot \pi}{3}\)

\(R^3\cdot \pi \cdot \left (\dfrac{cos^3 (\theta) -3 \cdot cos (\theta) + 2 }{3} \right )\)

\(R^3\cdot \pi \cdot \left (\dfrac{cos^3 (\theta) + 2 }{3} - cos (\theta) \right )\)

\(R^3\cdot \pi \cdot \left (\dfrac{cos^3 (\theta) }{3} + \dfrac{2}{3} - cos (\theta) \right )\)

Therefore, the correct option is πR³(2/3 + (1/3)cos³θ - cosθ).

Force = mass × acceleration

Now, keeping this formula in mind you can find the mass as follows;

= 35 = m × 3

= 35/3 = m

= 11.6 kg = m

And yeah its done!:)

To solve this problem, we can use the conservation of energy and the conservation of angular momentum.

Let's first find the gravitational potential energy at height D. The center of mass of the yo-yo drops by a distance of D/2, so the gravitational potential energy lost is:

ΔU = Mgd/2

where g is the acceleration due to gravity.

Next, we can use the conservation of energy to relate the gravitational potential energy lost to the kinetic energy gained:

ΔU = KE

1/2MV² = Mgd/2

where V is the linear speed of the yo-yo. Solving for V, we get:

V = √(gd)

Next, we can use the conservation of angular momentum to relate the initial angular momentum to the final angular momentum. Since the yo-yo starts from rest, its initial angular momentum is zero. At the bottom of the drop, the entire mass is rotating with an angular speed ω about the central axle. The moment of inertia of the yo-yo can be found by using the parallel axis theorem:

I = 2(1/2MR²) + 1/2M(1/2R)²

I = 5/4MR²

The final angular momentum is:

L = Iω

L = 5/4MR² ω

Since the string is unwinding without slipping from the central axle, the linear speed of any point on the yo-yo is related to its angular speed by:

V = ωR/2

Substituting for V, we get:

5/4MR² ω = 1/2MV²

5/4MR² ω = 1/2M(gd)

ω = (gd)/(5/2R)

Therefore, the linear speed of the yo-yo is V = √(gd), and the angular speed is ω = (gd)/(5/2R).

Explanation:

because Longitudinal waves are in which particles of the medium move directio ni. parallel to the energy transport.

I think this is ur answer

The torque on the shoulder joint is 21.4 N·m.

torque = force x distance x sin(theta)

weight = mass x gravity

where mass is 8.00 kg and gravity is 9.81 m/s². So,

weight = 8.00 kg x 9.81 m/s² = 78.5 N

torque = 78.5 N x 0.550 m x sin(30.0 degrees)

torque = 21.4 N·m

Torque is a measure of the rotational force or moment that is applied to an object, causing it to rotate around a fixed axis or pivot point. It is commonly expressed in units of Newton meters (Nm) or pound-feet (lb-ft) and is calculated by multiplying the force applied to the object by the distance from the pivot point to the point where the force is applied.

In simpler terms, torque is the amount of twisting force that is applied to an object, like a wrench turning a bolt or a motor turning a shaft. The greater the torque applied to an object, the greater the rotational acceleration produced, and the faster the object will rotate. Conversely, objects that are difficult to rotate require a greater torque to overcome their resistance and achieve rotation.

When the current flowing through an inductor is increasing, the voltage across the inductor also increases, according to Faraday's law of electromagnetic induction.

This phenomenon occurs due to the inductor's inherent property of opposing changes in current. As the current increases, the magnetic field around the inductor expands and induces a voltage across the inductor that opposes the current change. This induced voltage can be visualized as a back EMF (electromotive force) that opposes the driving voltage. The magnitude of the induced voltage depends on the rate of current change, the inductance of the coil, and the number of turns of the coil.

When a light wave travels from air into glass, the correct answer is:

B) Its speed decreases.

When light passes from one medium to another, such as from air to glass, it encounters a change in the refractive index of the material. The refractive index is a property of a medium that describes how much the speed of light changes when passing through that medium.

In general, the speed of light is slower in a denser medium like glass compared to air. As the light wave enters the glass, it slows down due to interactions with the atoms or molecules in the material. This change in speed is accompanied by a change in direction, which is known as refraction.

However, the wavelength of the light wave does not change significantly when it travels from air into glass, so option C is not correct. Similarly, the frequency of the light wave remains the same, as it is a property of the light wave itself and is not affected by the medium it travels through, making option E also incorrect.

Answer:

Average velocity = 82.22 km/h

Explanation:

Average Velocity = (Total distance)/(Total time)

When the car was first driven for 1 h with a velocity of 100 km/h towards the south

Velocity = Distance/time

Distance = Velocity * time

Distance covered, D1 = 100 * 1 = 100 km

When the car was driven for 0.50 h with a velocity of 50 km/h towards the north

Distance = Velocity * time

Distance covered, D2 = 50 * 0.5 = 25 km

When the car was driven for 0.75 h with a velocity of 80 km/h towards the south

Distance = Velocity * time

Distance covered, D3 = 80 * 0.75 = 60 km

Total distance traveled = D1 + D2 + D3

Total distance traveled = 100 + 25 + 60

Total distance traveled = 185 km

Total time taken = 1 + 0.5 + 0.75

Total time taken = 2.25 h

Average velocity = Total distance/ total time

Average velocity = 185/2.25

Average velocity = 82.22 km/h

the spring constant of the spring is k. the spring is initially compressed a distance x0. the block is released from rest.

Velocity is the measure of the amount of distance an object covers in a given amount of time. Here's a word equation that expresses the relationship between distance, velocity and time: Velocity equals distance travelled divided by the time it takes to get there.

Speed = Distance/Time – This tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance. Time = Distance / Speed, as the speed increases the time taken will decrease and vice versa.

The best combination of climatic conditions to maximize net primary productivity is warm temperatures, moderate precipitation, and ample sunlight.

Net primary productivity (NPP) refers to the rate at which plants and other autotrophs convert sunlight into biomass through photosynthesis, minus the amount of energy used in respiration. The climatic conditions that promote NPP are warm temperatures that allow for efficient photosynthesis, moderate precipitation to supply water and nutrients to plants, and ample sunlight for photosynthesis.

These conditions are typically found in regions with a temperate or tropical climate. However, excessive rainfall or drought can limit NPP, as can extreme temperatures or insufficient sunlight. Human activities, such as deforestation and land use change, can also reduce NPP by decreasing the amount of plant biomass available for photosynthesis. Overall, a balance of climatic conditions is essential for maximizing NPP and maintaining healthy ecosystems.

A wireless channel occupying frequency spectrum from 72GHz to 95GHz. The SNR of this channel is 60dB. The channel capacity is approximately 309.75 Gbps.

According to Shannon's theorem, the channel capacity (C) in bits per second is given by the formula:

C = B * log2(1 + SNR)

Where B is the bandwidth of the channel in hertz and SNR is the signal-to-noise ratio. In this case, the bandwidth (B) is the frequency span of the channel, which is 95 GHz - 72 GHz = 23 GHz = 23 × 10^9 Hz.

The SNR is given as 60 dB. To convert the SNR from decibels (dB) to the linear scale, we use the formula:

SNR_linear = 10^(SNR_dB / 10)

Substituting the values into the formula, we have:

SNR_linear = 10^(60 / 10) = 10^6

Now we can calculate the channel capacity:

C = 23 × 10^9 * log2(1 + 10^6)

The minimum angular separation that the human eye can resolve when viewing two stars, considering only diffraction effects, is 0.007°.

The minimum angular separation that the human eye can resolve when viewing two stars, considering only diffraction effects, can be determined using the Rayleigh criterion. The Rayleigh criterion states that the minimum angular separation that can be resolved by a circular aperture, such as the human eye, is given by:

θmin = 1.22λ/D

where θmin is the minimum angular separation, λ is the wavelength of light, and D is the diameter of the aperture.

For a human eye with a pupil diameter of 5.5 mm and a wavelength of 550 nm, the minimum angular separation can be calculated as follows:

θmin = 1.22(550 nm)/(5.5 mm)

=> 1.22(550 x 10^-9 m)/(5.5 x 10^-3 m)

=> 1.22 x 10^-4 rad

To convert from radians to degrees, we can use the following conversion factor:
