The distance between two successive peaks of a wave is called a wavelength.

In physics, wavelength refers to the distance between successive crests, troughs, or any other repeating pattern in a wave. It is denoted by the Greek letter lambda (λ). Wavelength is a fundamental property of waves and is commonly used to describe various types of waves, including electromagnetic waves (such as light and radio waves) and sound waves.

In the case of electromagnetic waves, wavelength represents the spatial extent of the wave and is typically measured in meters or multiples thereof, such as nanometers (10^-9 meters) or micrometers (10^-6 meters). Different types of electromagnetic waves have different wavelengths. For example, visible light consists of a range of wavelengths, with red light having longer wavelengths and blue light having shorter wavelengths.

In the context of sound waves, wavelength refers to the distance between successive compressions or rarefactions in the wave. It is commonly measured in meters or fractions of a meter, such as centimeters or millimeters.

The relationship between wavelength (λ), frequency (f), and the speed of the wave (v) is given by the equation: v = λf. This equation states that the speed of a wave is equal to the product of its wavelength and frequency.

The net force on an object is zero that is pulled with forces of 80 newtons to the right and 80 newtons to the left.

Net force is equal to sum of all the force acting on a body.

The formula for net force if n force are acting on it:

                       \(F_{net}=F_{1}+ F_{2}+F_{3}.....F_{n}\)

In this case the two forces are equal but opposite in direction.

Putting the values in the formula

\(F_{net} = 80+(-80)\) (since forces are equal but opposite)

\(F_{net}= 0\)

So the net force acting on the object is zero because the forces are equal and opposite.

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:

2.44 m/s due East

Explanation:

From the question given above, the following data were obtained:

Mass of 1st car (m₁) = 4 Kg

Velocity of 1st car (u₁) = 3 m/s

Mass of 2nd car (m₂) = 5 Kg

Velocity of 2nd car (u₂) = 2 m/s

Final velocity (v) =?

The final velocity can be obtained as follow:

v(m₁ + m₂) = m₁u₁ + m₂u₂

v(4 + 5) = (4×3) + (5×2)

9v = 12 + 10

9v = 22

Divide both side by 9

v = 22/9

v = 2.44 m/s

Thus, the final velocity is 2.44 m/s.

Since both cars was moving due East before collision, and after collision, they stick together, then their direction will be due East.

Answer:

(a) h = 5.1 m

(b) v = 14.13 m/s

Explanation:

(a)

We will use the law of conservation of energy. For this situation it states that:

Loss in Potential Energy of Sphere = Gain in Kinetic Energy of the Sphere

mgh = (1/2)mv²

h = v²/2g   --------------- equation (1)

where,

h = height = ?

v = speed at lowest point = 10 m/s

g = 9.8 m/s²

Therefore,

h = (10 m/s)²/(2)(9.8 m/s²)

h = 5.1 m

(b)

using the equation (1)

h = v²/2g

v = √2gh

where,

v = velocity = ?

g = 9.8 m/s²

h = height = 2(5.1 m) = 10.2 m

Therefore,

v = √[2(9.8 m/s²)(10.2 m)]

v = 14.13 m/s

The height from which the sphere was released is 5.1 m

When the height is doubled, the speed of the sphere becomes 14.14 m/s.

The given parameters:

The height from which the sphere was released is calculated as follows;

\(P.E = K.E\\\\mgh = \frac{1}{2}mv^2\\\\gh = \frac{1}{2}v^2\\\\h = \frac{v^2}{2g}\\\\h = \frac{(10)^2}{2(9.8)} \\\\h = 5.1 \ m\)

When the height is doubled, the speed of the sphere becomes;

\(h = \frac{v^2}{2g} \\\\v^2 = 2gh\\\\v = \sqrt{2gh} \\\\v = \sqrt{2 \times 9.8 \times (2 \times 5.1)} \\\\v = 14.14 \ m/s\)

Answer:

86400 seconds

Explanation:

To convert a mean solar day to second :

Number of hours in a solar day = 24 hours

Number of minutes per hour = 60 minutes

Number of seconds per minute = 60 minutes

Hence, the number of seconds in a solar day is :

(Number of hours in a solar day * number of minutes in an hour * number of seconds in a minute)

(24 * 60 * 60) seconds = 86400 seconds

Hence, 1 mean solar day = 86400 seconds

In order to replace the 700-N force P applied at point A, we can use two equivalent systems.

(a) For the first system, we can create an equivalent force-couple system at point C. This means applying a force of 700 N at point C in the opposite direction of the original force P, along with a couple moment. The magnitude of the couple moment would be 700 N multiplied by the perpendicular distance between points A and C.

(b) For the second system, we can replace the force P with a vertical force at point B and a second force at point D. The magnitude of the vertical force at B would be equal to 700 N, and the second force at D would have the same magnitude but in the opposite direction. These forces at B and D should be positioned in a way that the net effect is equivalent to the original force P at point A.

By using either the force-couple system at point C or the system with vertical forces at points B and D, we can achieve the same overall effect as the original force P at point A.

Answer:KE

Explanation:

Answer:

10 floors

Explanation:

We are told that a bell of mass 20 kg is atop a tower and has 8829 J of gravitational energy. The question asks us to estimate the number of floors the tower has.

To do this, we must first calculate how high above the ground the bell is. We can do that using the formula for gravitational potential energy:

\(\boxed{g.p.e = mgh}\),

where:

• g.p.e = gravitational potential energy (8829 J)

• m = mass of object (20 kg)

• g = acceleration due to gravity (approximately 10 m/s²)

• h = height of object above ground (? m).

Using the above information and formula, we can solve for h:

g.p.e = \(20 \times 10 \times h = 8829\)

       ⇒ \(200 h = 8829\)

       ⇒ \(h = \frac{8829}{200}\)

       ⇒ \(h = \bf 44.145 \ m\)

Therefore the bell is 44.145 m above the ground, which means that the height of the tower is also 44.145 m.

One floor of a building can be estimated to be around 4.3 m, therefore the number of floors the tower has is:

44.145 ÷ 4.3

≈ 10

Therefore there are 10 floors in the tower.

The height of the cliff is 8.7 meters while 65kg mass falls off a cliff and hits the ground with the velocity of 18.25m/s.

Velocity is a measure of an object's speed and direction of motion. It is a vector quantity, meaning it has both magnitude (speed) and direction. Velocity is often represented by the symbol "v" and is usually measured in meters per second (m/s). The velocity of an object can be changed by applying a force to it, causing it to accelerate. The acceleration can be positive, negative, or zero, depending on the direction and magnitude of the force.

Calculation for finding height of the cliff

The equation of motion to find the height of the cliff

\(h = vi \times t + 1/2 \times a \times t^2\)

where h is the height of the cliff, vi is the initial velocity (which is 0 m/s because the object is starting from rest), t is the time it takes to fall, and a is acceleration due to gravity \((9.8 m/s^2)\).  Final velocity of the object \((18.25 m/s)\) to find t should be used.

\(vf^2 = vi^2 + 2\times a \times h\)

\(18.25^2 = 0 + 2 \times9.8 \times h\)

Hence,

\(h = (18.25^2) / (2 \times9.8) = 170.5625 m/s^2 / 19.6 m/s^2 = 8.7 meters\)

Answer:

Explanation:

The main difference between Newtonian Science (Classical Science) and Quantum Science (Quantum Physics/Quantum Mechanics) lies in their fundamental principles and the scales at which they apply. Newtonian Science describes the motion of macroscopic objects in a deterministic manner using classical mechanics, while Quantum Science deals with the behavior of microscopic particles and is characterized by probabilistic predictions and wave-particle duality.

Newtonian Science (Classical Science): Newtonian Science is based on the laws of classical mechanics formulated by Sir Isaac Newton. It describes the motion of macroscopic objects, such as planets, projectiles, and everyday objects. It assumes that objects have definite positions and velocities, and their behavior is deterministic. The laws of motion, such as Newton's laws, provide precise predictions of the behavior of objects.

Quantum Science (Quantum Physics/Quantum Mechanics): Quantum Science is a branch of physics that deals with the behavior of particles at the atomic and subatomic level. It was developed in the early 20th century to explain phenomena that classical physics couldn't account for. Quantum mechanics introduces the concept of wave-particle duality, where particles exhibit both wave-like and particle-like properties. It uses mathematical formalism, such as wave functions and probability distributions, to describe the behavior of particles. Quantum mechanics is probabilistic in nature, providing predictions of the likelihood of different outcomes rather than precise deterministic predictions.

The main difference between Newtonian Science (Classical Science) and Quantum Science (Quantum Physics/Quantum Mechanics) lies in the scales at which they apply and their fundamental principles. Newtonian Science describes the motion of macroscopic objects using classical mechanics and provides deterministic predictions. On the other hand, Quantum Science deals with the behavior of microscopic particles, introduces wave-particle duality, and provides probabilistic predictions. Quantum mechanics revolutionized our understanding of the microscopic world, challenging the deterministic worldview of classical mechanics and laying the foundation for many modern technological advancements.
