I’m not sure but when’s the deadline
Answer:
Explanation:
Force of brick = 10 N
Area of surface = 20 cm^2
Pressure = force / area

= 1 / 2 or 0.5 Pa
Hope this hepls
plz mark it as brainliest!!!!!!!!
To be able to classify which species is which
The force due to gravity is equal to the product of the mass and acceleration due to gravity. Since the acceleration due to gravity is constant, we just have to rely on the comparison of their masses to determine the mass effect. Thus, the answer to this item is Wrestler C weighing 171 pounds.
