Answer:
30 °C
Explanation:
When you pour water from one glass to the other, the heat energy will flow from the hot water to the cold.
You have equal masses of water in each glass. The hot water should cool down as much as the cold water warms up.
The final temperature should be halfway between the starting temperatures in each glass.
(10 °C + 50°C)/2 = 60 °C/2 = 30°C
The temperature of the full glass of water should be 30 °C.

Explanation:
From the scattering experiments, Rutherford concluded that the positive charge was concentrated in the nucleus of the atom.
This contradicted the plum pudding model, which assumed that the positive charge was uniformly distributed throughout the atom.
Rutherford is very well-known for his gold foil experiment. He used alpha rays to strike the gold foil. Before this he also observed radioactive decay. But in the gold foil experiment, he discovered the nucleus and the proton. So, the acceptable answers are: <span><em>emissions of radioactive elements and the proton</em>.</span>
