On a cold winter day, João used a metal spoon to stir his hot soup and noticed that the handle of the spoon heated up quickly. Later, he decided to switch the metal spoon for a plastic one and realized that the handle of this spoon did not heat up as fast as the other. Based on his observations and the ways heat propagates, what is the reason for the difference in heat propagation in the handles of the metal and plastic spoons?a.
Metal is a good thermal conductor, while plastic is a thermal insulator.
b.
The metal spoon has a higher thermal capacity than the plastic one.
c.
The plastic is a good thermal conductor, while the metal is a thermal insulator.
d.
The plastic spoon has a higher thermal capacity than the metal one.
e.
Both materials are good thermal conductors, but metal conducts more slowly.

During a track and field event, the muscles in an athlete's legs contract and relax rapidly, enabling them to sprint at high speeds. For this movement to happen effectively, various systems in the human body must work together. Keeping in mind the role of the muscular and skeletal systems in movement, what is the primary function of bones while running?

During a practical in Science class, learners were tasked with creating different mixtures using materials readily available in the room, such as water, sand, oil, and sugar. At the end of the practical, the teacher requested each group to give a presentation on their observations and conclusions. Considering that the aim was to classify the mixtures as homogeneous or heterogeneous, which of the following options best describes the type of mixture formed when using water, oil, and sugar, and why?
