We want the reaction 188o + 11h --> 189f + 10h. what is the q-value of this reaction? is it endo- or exo-thermic? (m180=17.999161 u, mh=1.008665 u, mh=1.007825 u, m18f=18.000938 u ; all atomic masses, except neutron)
give mev.
do 10mev protons provide enough energy to drive this reaction?

answer; the correct answer is technician a; ///100%good luck

c) up is the direction the magnetic force is acting on the charge.

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
