Measure the distance from force to fulcrum and from load to fulcrum on your own arm and then calculate the force needed to hold in place a 25 pound load. Show your calculations. (Note: your distance measurements will be rough approximations)

i'm assuming that it's c.) red bank..

c. 75.7

i think that is the right

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
