When two hydrogen atoms bond the positive nucleus of one atom attracts the

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

i wanna say it’s between b and d, leaning more towards b.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
