The de Broglie wavelength for a particle== 0.92 ×10⁻³⁴m.

de broglie wavelength is the wavelength associated with particle of mass m moving with velocity v.

p= h/ λ

where, p -is  the momentum of the atom;

h- Planck's constant - 6.626×10⁻³⁴ m²kg s⁻¹

λ- wavelength;

Momentum can be expressed as

p=m×v

where , m is  the mass of the particle;

v - the speed of the particle.

so,

λ = h/(m×v)

= ( 6.626×10⁻³⁴ m²kg s⁻¹)/(1.2kg × 6.0 m/s)

Explanation:

Melting, change of a solid into a liquid when heat is applied.

Stars form from molecular clouds through a process known as stellar formation.

These clouds, characterized by low temperatures and high densities, provide the ideal conditions for atoms to combine and form molecules. With a mass range spanning from a few solar masses to millions of solar masses, molecular clouds serve as the birthplaces of new stars. The Pleiades cluster serves as a notable example of stars that have recently formed within such a stellar nursery.

The formation of stars from molecular clouds involves several key steps. Firstly, gravitational forces acting on regions of higher density within the cloud cause them to collapse under their own gravity. As the cloud collapses, it begins to fragment into smaller, denser clumps called protostellar cores. These cores continue to collapse, and their central regions become increasingly dense and hot. At this stage, they are known as protostars.

Paley's argument compares a watch to the universe/world, claiming that both exhibit similar attributes. He uses this analogy to argue for the existence of God.

Paley's Teleological Argument, often referred to as the argument from design, is based on the idea of purposeful design in the universe. The argument consists of the following premises and conclusion:

Premise 1: Watches are complex and exhibit intricate design, with various parts working together to fulfill a specific purpose.

Premise 2: The universe/world also exhibits complexity and intricate design, with various elements and processes working together.

Premise 3: If something exhibits complexity and design, it must have an intelligent designer.

Conclusion: Therefore, the universe/world must have an intelligent designer, which Paley identifies as God.

Paley argues that the attributes shared by a watch and the universe/world, such as complexity, order, and purposeful design, suggest the existence of an intelligent creator. He believes that just as the intricate design of a watch implies the existence of a watchmaker, the complexity and order observed in the universe imply the existence of a cosmic designer, namely God.

However, objections can be raised against Paley's argument:

a. There is no evidence that we can tell the world has a purpose: Critics argue that Paley's argument assumes the existence of purpose in the world without sufficient evidence. They contend that the appearance of design and order could be explained by natural processes rather than the intentional actions of a designer.

b. The universe seems to be more chaotic than ordered: Some objectors argue that the universe appears to exhibit more chaos and randomness rather than the ordered and purposeful design proposed by Paley. They point to natural disasters, genetic mutations, and other seemingly random events as evidence that the universe is not a well-designed system.

c. A watch is a bad analogy for the universe: Critics also challenge Paley's choice of analogy, asserting that a watch is not a suitable comparison for the universe. They argue that the watch is a human-made object with a known designer, whereas the origins and nature of the universe are fundamentally different and require distinct explanations. Furthermore, the watch is a limited and finite object, while the universe is vast and complex, making the analogy insufficient to support the existence of an omnipotent and infinite God.

These objections challenge the validity of Paley's argument by questioning the assumptions, evidence, and analogies he employs to establish a link between the design observed in the universe and the existence of a divine creator.

A straightforward harmonic oscillator's period is independent of its amplitude. with the graphs of acceleration and velocity produced by the time derivatives. These oscillators also show how kinetic and potential energy can be transferred.

To calculate the time it would take to withdraw your foot from a hot object, given the conduction velocity of a human nerve fiber, we need to consider the distance traveled and the conduction velocity of the nerve fiber.

The time taken to withdraw your foot can be determined by dividing the distance traveled by the conduction velocity of the nerve fiber. However, it is important to note that the conduction velocity of a nerve fiber refers to the speed at which the electrical signals travel along the nerve, not necessarily the speed at which you physically move your foot.

Assuming that the conduction velocity of 0.5 m/s represents the speed at which the sensation of pain or discomfort reaches your brain from the nerves in your foot, it may take additional time for your muscles to respond and physically withdraw your foot from the hot object.

Therefore, the time it would take to withdraw your foot from the hot object cannot be determined solely based on the conduction velocity of a nerve fiber. It would depend on various factors, including your reaction time, muscle response, and other physiological factors.

The force that needs to be applied to the small piston of the hydraulic press to lift a body weighing 70,000 N is approximately 495,833.33 N.

To calculate the force required to lift a body using a hydraulic press, we can use Pascal's principle, which states that the pressure applied to an enclosed fluid is transmitted equally in all directions.

In this case, we have a hydraulic press with a small piston of 12 cm² area and a large piston of 85 cm² area. The weight of the body to be lifted is 70,000 N.

Step 1:

Calculate the pressure on the small piston:
Pressure = Force / Area
Pressure = 70,000 N / 12 cm²

Step 2:

Calculate the force required on the large piston:
Force = Pressure x Area
Force = Pressure x 85 cm²

Let's solve these calculations.

Step 1:
Pressure = 70,000 N / 12 cm²
Pressure = 5,833.33 N/cm²

Step 2:
Force = 5,833.33 N/cm² x 85 cm²
Force = 495,833.33 N

Therefore, the force that needs to be applied to the small piston of the hydraulic press to lift a body weighing 70,000 N is approximately 495,833.33 N.

(a) The mass at time t=0 is 460 grams. (b) Rounding to at least one decimal place, the mass last after 45 years is about 119.0 grams.

(a) To find the mass at time t=0, we alternative into the given characteristic:

m(0) = \(460e^(-0.03(0))\)

Since \(e^0\) is the same for at least one, we've got:

m(0) = 460(1) = 460 grams

Therefore, the mass at time t=0 is 460 grams.

(b) To locate the mass final after 45 years, we substitute t=45 into the given function:

m(45) = \(460e^(-0.03(45))\)

Using a calculator or software program, we will evaluate the expression:

m(45) ≈ \(460e^(-1.35\)) ≈ 460(0.2587) ≈ 118.96 grams
