Adeflated hot air balloon weighs a total of 8000 n filled with hot air, the balloon rises to a height of 1000 m. how much work is accomplished by the hot air?

= 8,000,000 Joules

Work done is the product of force and distance. Work done is measured in Joules.

Therefore;

Work done = Force × Distance

Force = 8000 N,

Distance = 1000 m

Work done = 8000 N × 1000 m

                  = 8,000,000 Joules

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
