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

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
