what is the heat capacity of 100 kg of a coolant that has a specific heat capacity of 2420 J/KgK
A force acts on a 2-kg mass and gives it an acceleration of 3 m/. What acceleration is produced by the same force when acting on a mass of (a) 1 kg? (b) 4 kg? (c) How large is the force?
Let x be a random variable that represents the percentage of successful free throws a professional basketball player makes in a season. Let y be a random variable that represents the percentage of successful field goals a professional basketball player makes in a season.
The table below shows the percentage of successful free throws and field goals a professional basketball player makes in a season:

As a variation of the preceding problem explore the consequences of increasing the energy separation of the ψB and ψC orbitals (use SAB and SAC equal to 0 for this stage of the calculation). Are you justified in ignoring orbital ψC at any stage?
Show, if overlap is ignored, (a) that if a molecular orbital is expressed as a linear combination of two atomic orbitals in the form ψ = ψA cos θ + ψB sin θ, where θ is a parameter that varies between 0 and π, with ψA and ψB are orthogonal and normalized to 1, then ψ is also normalized to 1. (b) To what values of θ do the bonding and antibonding orbitals in a homonuclear diatomic molecule correspond?
Estimate the orbital energies to use in a calculation of the molecular orbitals of HBr. For data, see Tables 8B.4 and 8B.5. Take β = −1.00 eV.
