The energy required for long walk in joules and in kilojoules should be calculated. Concept Introduction: One calorie is defined as 4.184 J. The conversion factors can be written as, 1 cal = 4.184 J ( 1 cal 4 .184 J ) and ( 4 .184 J 1 cal ) One kilocalorie (kcal) is equal to 1000 calories, and one kilojoule (kJ) is equal to 1000 joules. The equalities and conversion factors follow: 1 kcal = 1000 cal ⇒ ( 1 kcal 1000 cal ) and ( 1000 cal 1 kcal ) 1 kJ = 1000 J ⇒ ( 1 kJ 1000 J ) and ( 1000 J 1 kJ )

Interpretation Introduction

Interpretation: The energy required for long walk in joules and in kilojoules should be calculated.

Concept Introduction:

One calorie is defined as 4.184 J. The conversion factors can be written as,
1 cal = 4.184 J( 1 cal 4.184 J )and ( 4.184 J 1 cal)

One kilocalorie (kcal) is equal to 1000 calories, and one kilojoule (kJ) is equal to 1000 joules. The equalities and conversion factors follow:
1 kcal = 1000 cal ⇒ ( 1 kcal 1000 cal) and ( 1000 cal 1 kcal)1 kJ = 1000 J ⇒ ( 1 kJ 1000 J ) and ( 1000 J 1 kJ)

In the spectroscopic technique known as photoelectron spectroscopy (PES), ultraviolet radiation is directed at an atom or molecule. Electrons are ejected from the valence shell and their kinetic energies are measured. Since the energy of the incident ultraviolet photons is known and the kinetic energy of the ejected electron is measured, the ionization energy, I, can be deduced because total energy is conserved. (a) Show that the velocity, v, of the ejected electron and the frequency, n, of the incident radiation are related by hv = I + (1/2)mv^2? (b) Use this relation to calculate the ionization energy of a rubidium atom, knowing that light of wavelength 58.4 nm produces electrons with a velocity of 2,450 km/s Recall that 1 J = 1 kg.m^2/s^2

I) In Millikan's experiment, each droplet observed by the technicians contained an even number of electrons. If they had been unaware of this limitation, how would it have affected their report of an electron's charge?II) Millikan measured the charge of an electron in electrostatic units, esu. The data he collected included the following series of charges found on oil drops: 9.60 X 10^-10 esu, 1.92 X 10^-9 esu; 2.40 X 10^-9 esu; 2.88 X 10^-9 esu; and 4.80 X 10^-9 esu. (a) From this series, find the probable charge of the electron in electrostatic units. (b) Estimate the number of electrons in an oil drop with a charge of 6.72 X 10^-9 esu. The actual charge (in Coulombs) of an electron is 1.602 X 10^-19 C. What is the relationship between esu and Coulombs?
