Answer:
Explanation:
To show the sequence of electrons filling sublevels in an atom, the Aufbau's principle is one of the tenets that must be satisfied to write a proper notation.
- Aufbau's principle states that "the sublevels with lower energies are filled up before those with higher energies".
- Note that based on this principle, we are not inferring that sublevels are filled in numerical order.
- The patter of filling is shown below:
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f e.t.c
Main function of haemoglobin in the body is to transport oxygen to every cell/organ of the body

Answer:
Explanation:
Mass and weight are quite different terms .
Weight is defined as the amount of force exerted on the earth due to our mass and gravity of acceleration.
Given that the mass is 90 kg and gravity of acceleration of earth is 9.82 m/s^2.
So weight will be
So this is the weight of the 90kg man standing on earth.
