Answer:
Centripetal acceleration of the wheel is 
.
Explanation:
We have,
Diameter of a Ferris wheel is 60 m
Radius of the wheel is 30 m
Speed of the wheel is 2.09 m/s
It is required to find the centripetal acceleration of the wheel. The formula of centripetal acceleration is given by :
So, the centripetal acceleration of the wheel is .
when the top of the pencil moves in one direction, the bottom end on the ground will move in another, but due to the frictional force it will move by a lesser amount, and the center of mass of the pencil will be accelerated in the horizontal direction due to the force of friction
The partial pressure of carbon dioxide is 75 torr.
<h3>What is Dalton's theory?</h3>
Dalton's theory of gas states that total pressure of the mixture of gas sample is equal to the sum of the partial pressure of all the gases present in that sample.
Given that,
- Total pressure of mixture = 825 torr
- Partial pressure of Nitrogen = 600 torr
- Partial pressure of oxygen = 150 torr
- Partial pressure of carbon dioxide = ?
On putting values, we get
Partial pressure of carbon dioxide = 825 - (600 + 150) = 75 torr
Hence Partial pressure of carbon dioxide is 75 torr.

Answer:
Through oxidation of food materials
Explanation:
When living organisms eat, they ingest complex organic food materials. As these food materials enter the body, the process of digestion begins.
Enzymes in the body, located at different parts of the gastrointestinal tract see to the breakdown of these complex food materials ingested. The oxidation of these complex food materials lead to the release of the chemical potential energy stored in them.
The ground state electronic configuration has the lowest energy distribution of the electrons. correct option is (A).
The energy associated to an electron is that of its orbital. The energy of configuration is often approximated as the sum of the energy of each electron, neglecting the electron electron interactions.
The configuration that corresponds to the lowest electronic energy is called the ground state. Any other configuration is an excited state.
As an example, the ground state configuration of the sodium atom is 1s2 2s2 2p6 3s1, as deduced from Aufbau principle.
