Travelling with velocity 1) calculate the energy e (in ev) and direction vector ω for a neutron v= 2132 +3300+154 k [m/sec]. (3 points) ^ ^

Explanation:

Given:

Velocity vector

the mass of neutron, m = 1.67 × 10⁻²⁷ kg

Now,

the kinetic energy (K.E) is given as:

or

or

substituting the values in the K.E equation

or

also

1J = 6.242 × 10¹⁸ eV

thus,

Now, the direction vector

or

or

or

b) phosphorus pentoxide

answer: decibel
