Answer:
B
Explanation:
Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.
The buoyancy of an object depends on its density relative to the density of the fluid it's placed in, typically water in everyday scenarios. When an object is placed in a fluid (like water), it will float if its average density is less than that of the fluid. In other words, if the object is less dense than the fluid, it will float.
In this case, both pieces of wood have the same density of 0.90 grams per milliliter (g/ml), which is less dense than water. Therefore, both the 1-pound piece of wood and the 10-pound piece of wood will float in water.
However, it's important to note that the buoyant force acting on these objects will be the same for a given volume of wood because they have the same density.
The 10-pound piece of wood will displace more water (have a larger volume) to support its weight, while the 1-pound piece of wood will displace less water (have a smaller volume) to support its weight. The 10-pound piece of wood will have more of its volume submerged compared to the 1-pound piece due to the weight difference, but both will float.

Explanation:
The marathon is set to start in two weeks and the young man starts his training from the last week exercising three to four times a week. So this requires a lot of strength and a lot of hard work. So as there is only two weeks time for him, he needs to train regularly in order to increase his stamina and strength to run and win the marathon. He should remain hydrated all the time so that his body functions properly and does not affect his health. He should work on his speed and stamina and exercise regularly to keep him fit and be able compete in the marathon.
Explanation:
A specie with no charge and containing one or more number of unpaired electrons is known as a free radical.
These free radicals tend to attain stable configuration by gaining an electron from another atom. Hence, they fill their outer energy levels.
For example, a free radical of chlorine will readily combine with a hydrogen atom in order to attain stability and it leads to the formation of a new chemical bond between the hydrogen and chlorine atom.
As a result, it will form a hydrogen free radical.
Thus, we can conclude that free radical is a highly reactive chemical species with one or more unpaired electrons.
A free radical is a highly reactive chemical species with one or more unpaired electrons. They actively participate in chemical reactions due to their need to complete their electron shell. These radicals can be both harmful and beneficial, depending on their context.
A free radical is a highly reactive chemical species with one or more unpaired electrons. These species are reactive because they seek to complete their electron shell by forming pairs, making them eager to engage in chemical reactions.
For instance, in combustion processes, free radicals like hydroxyl (OH) play a crucial role. Despite their reputation for causing damage in biological systems, free radicals are also beneficial as they are used by the immune system to neutralize pathogens.
