Answer: They would both be pushed backward. (READ EXPLANATION)
Explanation:
Since your question has an error in it, I will provide two answers. If they were standing on their feet, they would not move. if they're both standing on skateboards, they would both move backwards because they have no friction on the ground. if both of them are standing on the same skateboard and pushing against each other, they would not move.

Rutherford's experiment was done to prove Thompson's Plum Pudding Model. In this model, the protons and electrons are both inside the nucleus. The atoms is neutral because the charges cancel out. Rutherford's hypothesis was that, when a beam of cathode rays hits the gold foil, all the light should pass through. If the Plum Pudding model was correct, that would have been the result. However, it wasn't.
Five to ten million years ago, the tops of underwater Galapagos volcanoes appeared above water for the first time about 600 km from mainland Ecuador in the middle of the Pacific Ocean. Those volcanic peaks were completely devoid of plant and animal life. All plants and animals that are now native to the islands must have arrived to the islands originally through some form of long-distance dispersal.There are two main ways for species to make their way to remote islands. The first method is by air in the form of flying or being blown by wind, and the second method is by sea while swimming or floating, sometimes with the aid of rafts of tangled vegetation.
