Answer:
Yellow does not attract hummingbirds.
Explanation:
The most food wasn't taken out of the yellow feeders.
Answer:
52.1 degrees C
Explanation:
We need to use the equation: q = mCΔT, where m is the mass in grams, C is the specific heat capacity, and ΔT is the change in temperature.
Here, m = 10 g and q = 125 J. The heat capacity of iron is about 0.461 J/(g * C). And, our initial temperature is 25. So:
125 J = (10 g) * (0.461 J/(g * C)) * (T_f - 25)
Solving for T_f (final temp), we get: 52.1 degrees C
Hope this helps!

The British scientist Ernest Rutherford postulated the nuclear model of the atom in the early 1900s. He described his model as the atom being mostly empty space with electrons having a fixed orbit around the positively charged nucleus of the atom. The experiment he conducted to arrive at the model is known as the thin-foil experiment. He passed a narrow beam of particles through a thin film of metal foil and observed that the particles were only slightly scattered. It was with this observation that he concluded that most of the mass of a particle is concentrated only in a minute fraction of the total volume of the atom.
