Decide which examples are Nuclear Fission reaction. A. The reaction that is currently used in nuclear power plants.
B. Two small atoms combine together to form one larger atom.
C. A heavy atom is split when bombarded by neutrons.
D. Often involves isotopes of uranium

A) A, C, D
B) A, B, C
C) B, C, D

a,c,d, is your answer I think I hope it helps

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
