Determine the tangential speed of the moon given the mass of Earth and the distance from Earth to the moon

how about u try it first

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
