Derive the component manipulation rules (1.9g) and (1.9h). In component notation, the inner product of two vectors and the value of a tensor when vectors are inserted into its slots are given
The third-rank tensor S(___ , ___ , ___) and vectors A and B have as their only nonzero components S123 = S231 = S312 = +1, A1 = 3, B1 = 4, B2 = 5. What are the components of the vector C = S(A, B,
(a) Consider a perfect fluid with density ρ, pressure P, and velocity v that vary in time and space. Explain why the fluid’s momentum density is G = ρv, and explain why its momentum flux (stress
(a) An electric field E exerts (in SI units) a pressure ∈oE2/2 orthogonal to itself and a tension of this same magnitude along itself. Similarly, a magnetic field B exerts a pressure B2/2μo =
Use Eqs. (1.25) and (1.26) to derive the usual formulas dA = dxdy and dV = dxdydz for the 2-dimensional and 3-dimensional integration elements, respectively, in righthanded Cartesian coordinates.
Integrate the vector field A = zez over a sphere with radius a, centered at the origin of the Cartesian coordinate system (i.e., compute A · d∑).(a) Introduce spherical polar coordinates on the
In Euclidean 2-space, let {e1, e2} be an orthonormal basis with positive volume.(a) Show that the components of ∈ in this basis are(b) Show that €12 = +1, €21= -1, €11= €22=0. (1.24a)
Convert the following equations from the geometrized units in which they are written to SI units.(a) The “Planck time” tP expressed in terms of Newton’s gravitation constant G and Planck’s
Here is an example of how to use index notation to derive a vector identity for the double cross product A × (B × C): in index notation this quantity is ∈ij kAj (∈klmBlCm). By permuting the
From its complete anti-symmetry, derive the four properties of the Levi-Civita tensor, in n-dimensional Euclidean space, that are claimed in the text following Eq. (1.20). volume (A, B, ...,
One of Maxwell’s equations says that ∇ × E=−∂B/∂t (in SI units), where E and B are the electric and magnetic fields. This is a geometric relationship between geometric objects; it requires
(a) The following expressions and equations are written in slot-naming index notation. Convert them to geometric, index-free notation: AiBjk, AiBji, Sijk = Skji ,AiBi = AiBjgij .(b) The
