Answer to Problem 8P

The missing neutrinos in πμ+? is v¯μ_ .

Explanation of Solution

Consider table 15.2 and refer equation 15.1,

The missing neutrinos in pion are Muon-neutrino.

    πμ+v¯μ        (I)

Here, π is the pion, μ is the muon and v¯μ is the muon-neutrino.

Conclusion:

In this case, the muon-lepton is conserved.

    Lμ:011

Therefore, the missing neutrinos in πμ+? is v¯μ_.

Moon Knight, from both comics and the show of the same name, has crescent shaped daggers he throws at enemies. To throw a crescent dagger he applies a force of 0.918 N at an angle of 75.0° relative to the dagger’s center of mass at a point 0.0690 m away from the dagger’s center of mass. If the crescent dagger has a moment of inertia of 2.57⋅10^−5 kg⋅m^2 , what is the angular acceleration of a crescent dagger as it is thrown?
Because you are taking physics, your friend asks you to explain the detection of gravity waves that was made by LIGO in early 2016. (See the section that discusses LIGO.) To do this, you first explain about Einstein's notion of large masses, like those of stars, causing a curvature of spacetime. (See the section on general relativity.) To demonstrate, you put a bowling ball on your bed, so that it sinks downward and creates a deep depression in the mattress. Your sheet has a checked pattern that provides a nice coordinate system, as shown in the figure below. This is an example of a large mass (the bowling ball) creating a curvature of a flat, two-dimensional surface (the mattress) into a third dimension. (Spacetime is four dimensional, so its curvature is not easily visualized.) Then, you are going to amaze your friend by projecting a marble horizontally along a section of the sheet surface that is curved downward by the bowling ball so that the marble follows a circular path, as…
