445/100 - 5/4 = 445/100 - 125/100 = 320/100 = 16/5 = 3 1/5.
Answer:
The force exerted by the block on the floor is 38.4 Newtons
Explanation:
The given parameters are;
The area of the box in contact with the floor, A = 2.4 m²
The pressure exerted by the block on the floor, P = 16 N/m²
The force exerted by the box on the floor is given as follows;
∴ F = P × A
From the question, P = 16 N/m², and A = 2.4 m²
∴ F = 16 N/m² × 2.4 m² = 38.4 N
The force exerted by the block on the floor, F = 38.4 N.
The viscous force refers to the resistance of a fluid to flow. It is measured in Newton-second per square meter.
- The viscous force can be defined as the resistance that a fluid has to flow in a given space.
- Viscous force is proportional to the fluid velocity, while this constant is called viscosity.
- The viscous force can be measured in Newton-second per square meter (abbreviated as N s/m2).
