We have,
- Mass of both students is 60 kg
- Surface area of heels of one student say A is 0.45 cm² = 0.45/10000 m²
- Surface area of heals of another student say B is 74 cm² = 74/10000 m²
And we know that,
Here, area is provided but the force applied will be due to the acceleration of gravity so,
- F = ma
- F = 60 × 9.8
- F = 588
Now, let us calculate the pressure applied by both students;
Pressure(Student A)
- P = 588/0.45 × 10000
- P = 58800 × 10000/45
- P = 1306.6 × 10000
- P = 1306000.0 pascal
Pressure(Student B)
- P = 588/74 × 10000
- P = 5880000/74
- P = 7837.83
From the above two solutions we can say that, Pressure(Student A) > Pressure(student B)
And thus we can also say that,

B. The kinetic energy will decrease.
B.sunnny cold probable rain
D is correct answer.
Action potential it has a electrical signals that are generated by the movement of ions it across to the cell membrane of a neuron.
Hope it helped you.
