Not enough food to eat is A: Abiotic
Answer:
option D = 204 Pa
Explanation:
Given data:
Weight of book = 12 N
Area of book = 0.21 m × 0.28 m = 0.0058 m²
Pressure of book = ?
Solution:
formula
pressure = force / area
P = f/ A
now we will put the values in formula,
P = 12 N/ 0.0058 m²
P= 204 Nm⁻² ( Nm⁻²= Pa)
P = 204 Pa
