The table represents the forces on four objects, with directions. Object F1 ↑ F2 → F3 ← F4 ↓
W 30 N 20 N 20 N 30 N
X 15 N 35 N 25 N 15 N
Y 60 N 0 N 0 N 60 N
Z 45 N 0 N 22 N 45 N
Which best explains the forces acting on the objects?

Objects W and X have balanced forces, and objects Y and Z have unbalanced forces.
Objects W and Y have balanced forces, and objects X and Z have unbalanced forces.
Objects X and Y have balanced forces, and objects W and Z have unbalanced forces.
Objects X and Z have balanced forces, and objects W and Y have unbalanced forces.
please answer quick

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

what is the actual question though?

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
