D. Decrease it’s gravitational energy

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:
