Scalar fields (eg. the Higgs boson is an example of a scalar field) are posited to solve a number of cosmological challenges, namely that of dark energy and inflation. In this shorter problem we are going to determinp the dynamics of scalar fields. A scalar field ф is fully determined by its potential (the function that describes its potential energy): V(ø). You can think of this as a ball 'rolling down a hill', where the shape of the hill is...

problem 40 with parts
40. The atmospheric pressure (force per unit area) on a surface at an altitude z is due to the weight of the column of air situated above the surface. Therefore, the difference in air pressure p between the top and bottom of a cylindrical volume element of height Az and cross-section area A equals the weight of the air enclosed (density ρ times volume V-: ΑΔε times gravity g), per unit area: Let Δ、→0 to derive...

PLEASE PLEASE PLEASE Explain each part of the solution process. I'm trying to learn this and not just get an answer. I appreciate the help!! A new speedboat with mass m is traveling at v0 at some zero time when its engine is shut off. The magnitude of the frictional force fk between the boat and water is proportional to the speed v of the boat. As an equation, the magnitude of fk is equal to v, where v is...

1. A football has a mass of mp = 0.413 kg. It can be approximated as an ellipsoid 6 in diameter and 12 in long. A 'Hail Mary' pass is thrown upward at a 45° angle with an initial velocity of 55 mph. Air density at sea level is p= 1.22 kg/m². Neglect any spin on the ball and any lift force. Assume turbulent flow and a constant air-drag coefficient of Cp = 0.13. The equation of motion of the...
