Show that the neutron half-life (bs) is 0.693 × tmean, what is the half-life of a neutron unbound to a nucleus? provide an explanation of why the neutron is stable at all in the earliest epoch of cosmogenic nucleosynthesis. what is the relationship between the neutron and the phenomenon of b-decay?

What is friction? how does it affect the motion of an object?

Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line. what does this indicate about the object's acceleration?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
