Answer:
P = 1333.33 N
Explanation:
The pressure exerted by the boy on the floor can be calculated by the following equation:
where,
P = Pressure exerted by the boy = ?
F = Force Applied = Weight of Boy = 40 kg = 40 N (since 1 kg = 1N)
A = Area of application of force = 2(Area of one show) = 2(6 cm x 25 cm)
A = 2(0.06 m x 0.25 m) = 0.03 m²
Therefore,
<u>P = 1333.33 N</u>
C) Staring At Someone's Body, Giving Them The “Once Over”
The net force (magnitude and direction) of the system given in the question is 40 N horizontal to the right
<h3>How to determine the net force</h3>
Case 1 (Net force between up and downward force)
- Force up (Fu) = 50 N
- Force down (Fd) = 30 N
- Net force 1 (F1) = ?
F1 = Fu - Fd
F1 = 50 - 30
F1 = 20 N up
Case 2 (Net force between right and left)
- Force right (Fr) = 60 N
- Force left (Fl) = 20 N
- Net force 2 (F2) = ?
F2 = Fr - Fl
F2 = 60 - 20
F2 = 40 N right
SUMMARY
- Net force between up and down = 20 N up
- Net force between right and left = 40 N right
From the above, the net force between right and left (i.e 40 N) is greater than the net force between up and down (i.e 20 N)
Thus, the net force of the system will be 40 N horizontal to the right

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
That's true.
If a single atom of an element in a molecule required a subscript,
then water would be H₂O₁ , and salt would be Na₁Cl₁ .
