Chapter 4: Problem 105

Which of the fundamental forces has the shortest range, yet is responsible for producing the sunlight that reaches Earth?

Short Answer

Expert verified
Please provide a brief explanation of its role in sunlight production. Answer: The weak nuclear force is the fundamental force with the shortest range and is responsible for producing sunlight. It plays a crucial role in the fusion processes in the Sun's core, where protons are converted into neutrons through weak nuclear interactions. These interactions release high-energy photons that eventually reach Earth as sunlight.

Step by step solution

01

List the four fundamental forces

There are four known fundamental forces: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. Each force has a unique range, strength, and role in the world of physics.
02

Identify the fundamental force with the shortest range

Among the four fundamental forces, the weak nuclear force has the shortest range. Its range is limited to a distance of around 10^{-18} meters, which is much smaller compared to the ranges of the other three forces.
03

Explain the role of the weak nuclear force in producing sunlight

The weak nuclear force plays a crucial role in the fusion processes that occur in the core of the Sun. These fusion processes involve protons being converted into neutrons through weak nuclear interactions. As a result of these interactions, high-energy photons are released, which eventually reach Earth as sunlight. Thus, the weak nuclear force is the fundamental force with the shortest range and is responsible for producing the sunlight that reaches Earth.

Most popular questions from this chapter

Find the altitudes above the Earth's surface where Earth's gravitational field strength would be (a) two thirds and (b) one third of its value at the surface. [Hint: First find the radius for each situation; then recall that the altitude is the distance from the surface to a point above the surface. Use proportional reasoning.]
A box sits on a horizontal wooden ramp. The coefficient of static friction between the box and the ramp is 0.30 You grab one end of the ramp and lift it up, keeping the other end of the ramp on the ground. What is the angle between the ramp and the horizontal direction when the box begins to slide down the ramp? (tutorial: crate on ramp)
In a playground, two slides have different angles of incline \(\theta_{1}\) and \(\theta_{2}\left(\theta_{2}>\theta_{1}\right) .\) A child slides down the first at constant speed; on the second, his acceleration down the slide is \(a .\) Assume the coefficient of kinetic friction is the same for both slides. (a) Find \(a\) in terms of \(\theta_{1}, \theta_{2},\) and \(g.\) (b) Find the numerical value of \(a\) for \(\theta_{1}=45^{\circ}\) and \(\theta_{2}=61^{\circ}.\)
A crate of potatoes of mass \(18.0 \mathrm{kg}\) is on a ramp with angle of incline \(30^{\circ}\) to the horizontal. The coefficients of friction are \(\mu_{\mathrm{s}}=0.75\) and \(\mu_{\mathrm{k}}=0.40 .\) Find the frictional force (magnitude and direction) on the crate if the crate is at rest.
A book rests on the surface of the table. Consider the following four forces that arise in this situation: (a) the force of the Earth pulling on the book, (b) the force of the table pushing on the book, (c) the force of the book pushing on the table, and (d) the force of the book pulling on the Earth. The book is not moving. Which pair of forces must be equal in magnitude and opposite in direction even though they are not an interaction pair?
