Kindly explain newton's formula for the speed of sound

A massive body will accelerate or alter its velocity at a constant rate when a constant force is applied to it, according to Newton's second law. In the simplest case, when a force is applied to an object at rest, it accelerates in the force's direction.

Acceleration is the term used in mechanics to describe the pace at which the velocity of an object varies over time. Acceleration is a vector quantity (in that they have magnitude and direction). The direction of an object's acceleration is determined by the direction of the net force acting on it.

It is a vector quantity with an SI unit is m/s² and the dimension formula is LT⁻².

An object's motion is altered by a net force; the larger the net force, the higher the acceleration. To accelerate at the same rate as less massive objects, heavier net forces are needed.

According to Newton's second law, a massive body will accelerate, or change its velocity, at a constant rate, when a constant force is applied to it. In the most basic scenario, when a force is applied to an object at rest, it accelerates in the force's direction. However, depending on the force's direction and the directions that the object, as well as reference frame, as well as reference frame, are moving in relation to one another, a body that is already moving or being observed from a shifting inertial reference frame may appear to accelerate, decelerate, or change direction.

Explanation:

The greater the charge, the greater the electric force. The second factor is the distance between the charges.

The magnitude of the acceleration of the descending block is equal to 1.96 m/s².

Tension can be described as a force acting along the length of a rope or a cable, especially a force that comprises by a flexible medium. Tension can be described as an action-reaction pair of forces acting at each end of the length of the medium. Each endpoint carried tension and force from the weight attached.

Given that the block with mass, M₁ = 4m is placed on the horizontal table.

The block with mass, M₂ = m is attached by a string.

The block (M₂) suspended by the string experiences tension (T) in the upward direction and weight in the downward direction.

M₂g - T = M₂a                                                     ..............(1)

The block (M₁) placed on the table experienced only one force which is tension (T)

T = M₁ a                                                          .....................(2)

From equation (1) and (2):

M₂g -  M₁a  = M₂a  

M₁a  + M₂a  = M₂g

(M₁ + M₂) a =  M₂g

a = M₂g/(M₁ + M₂)

Substitute the value of masses of the blocks:

a = m g /( 4m + m)

a = g/5

a = 1.96 m/s²

The force needed to stretch a wire depends on its properties, specifically its Young's modulus, cross-sectional area, and the amount of stretch applied.

Assuming that the wires have the same Young's modulus and are stretched by the same amount, we can use the following formula to calculate the force needed:

F = (Y * A * delta_L) / L

where F is the force needed, Y is the Young's modulus, A is the cross-sectional area, delta_L is the amount of stretch applied, and L is the original length of the wire.

Since the second wire is twice as long and has twice the diameter of the first wire, its cross-sectional area is four times greater than the first wire. Therefore, we can calculate the force needed for the second wire as follows:

F_2 = (Y * 4A * delta_L) / (2L)

F_2 = (2Y * A * delta_L) / L

where F_2 is the force needed for the second wire.

Since the second wire has the same material and Young's modulus as the first wire, we can simplify the equation further:

F_2 = 2F_1

where F_1 is the force needed to stretch the first wire by the same amount.

Therefore, the force needed to stretch the second wire by 1.0 mm is twice the force needed to stretch the first wire by the same amount.

Yes, there are fundamental differences between Teflon or Lucite (both polymers) and brass (a metal). These differences arise from variations in their chemical composition, structure, and properties.

1. Chemical Composition: Teflon is a synthetic fluoropolymer made primarily of carbon and fluorine atoms, while Lucite is a type of acrylic polymer composed of carbon, hydrogen, and oxygen. On the other hand, brass is an alloy composed mainly of copper and zinc, with small amounts of other elements.

2. Structure: Teflon and Lucite are both polymers, meaning they consist of long chains of repeating units. Teflon has a linear structure, while Lucite has a more complex, three-dimensional structure. In contrast, brass has a metallic crystal lattice structure formed by the arrangement of copper and zinc atoms.

3. Physical Properties: Teflon and Lucite are known for their low friction, excellent chemical resistance, and electrical insulation properties. They have low melting points and are generally lightweight and transparent. Brass, being a metal, has higher density, good electrical and thermal conductivity, and is malleable and ductile.

4. Mechanical Properties: Teflon and Lucite are relatively soft materials with low tensile strength and hardness. They have good flexibility and can be easily molded or formed. Brass, as a metal, has higher tensile strength and hardness, making it more rigid and durable.

5. Applications: Teflon and Lucite find applications in various industries, such as coatings, electrical insulation, non-stick cookware, and medical devices. Brass is commonly used in plumbing fixtures, musical instruments, decorative items, and electrical connectors.

Answer:

Explanation:

In physics, work can be described as force multiplied by the displacement of the object (distance caused by the force acted on the object).

Work is a form of energy, therefore, it is measured in joules.

If Alex pushed on an object with 10N of force, and the object moved 2 meters, the work of Alex will be equal to:

W = Ft

W = 10N * 2m

W = 20 Joules

But, if we have John, that pushed on an object with 2N of force, but, since the object was way smaller, therefore it had way less inertia, the object moved a distance equal to 10 meters. Let's also calculate his work.

W = Ft

W = 2N * 10m

W = 20 Joules

And we got the same result.

Work can also be used to calculate power.

Power is equal to P = Work / time

It can also be written as P = delta Work / delta time

Power is measured in joules per second.

With power you can make the difference between someone that got a 2 kg object up in 2 second, and someone that got a 2 kg object up in 5 second.

The more powerful one would be the one who managed to make the same work in less time.

Hope it Helped!

Work is described as: the measure of energy transfer resulting from the application of force over a displacement.

In the field of physics, work is most accurately defined as the outcome of multiplying the force exerted on an object by the distance the object is displaced in the same direction as the force.

This calculation serves to quantify the energy transferred to or from the object. For instance, if an individual applies a 50 Newton force to push a box across a 5-meter distance in the force's direction, the work done on the box would equal 250 Joules (50 N × 5 m).

Answer:

Explanation: Let assume that bars are labeled A and B

Method 1

Using just the identical appearing bar magnet and unmagnetized iron bar.

Place the end of bar A in the middle of bar B.

If bar A sticks to bar B, then bar A is the magnet and bar B the umagnetized iron bar.

If bar A jumps to one of the ends of bar B, then bar B is the magnet.

Reason been that the magnetic field on a bar magnet is greatest at the two poles where the field comes out of the magnet. The center, between the poles, will be the weakest part of the field.

Method 2

Another solution would be to separate the two by quite some distance, float them on a piece of cork/wood in a plastic bucket or suspend them from long strings, then see which one consistently (eventually) lines up tending towards the Earth’s magnetic field.

The order of intermolecular forces among the given compounds will be as follows: H F > H Cl > H Br > H I

Electronegativity is defined as the property of the element to attract the shared pair of electrons towards itself.

Strongest intermolecular forces of attraction means that the electronegativity difference between the elements forming bond is more, more polar is the bond.

Electro negativities of the elements are:

Hydrogen: 2.1

Fluorine: 3.98

Chlorine: 3.16

Bromine: 2.96

Iodine: 2.66

Electro negativity difference in H F = 3.98 - 2.1 = 1.88

Electro negativity difference in H Cl = 3.16 - 2.1 = 1.06

Electro negativity difference in H Br = 2.96 - 2.1 = 0.86

Electro negativity difference in H I = 2.66 - 2.1 = 0.56

As, the electronegativity difference of H F is the highest, so it has the strongest intermolecular forces of attraction.

Thus, the order of intermolecular forces among the given compounds is H F > H Cl > H Br > H I.
