Answer:
Gravitational and resistance force.
Explanation:
The push or pull on any object which causes an object to move is called force. The forces can be of many types. The forces acting on the falling leaf are :
Answer:
Approximately , assuming that and that air resistance is negligible.
Explanation:
Let upward be the positive direction. Under the assumptions, acceleration of the stone would be (negative since the stone is accelerating downward.)
The duration of the flight can be found in the following steps:
In SUVAT equation :
Rearrange this equation to find :
.
In other words, the velocity of this stone has changed from the initial value of to during the flight. Divide the change in velocity by acceleration (the rate of change in velocity) to find the duration of the flight:
.
In other words, the stone would be in the air for approximately .
Answer:The amplitude is approximately 4.52 h x 2.3 f(t)
Explanation:
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.
