This problem is very vague since no other details are
given. However for the sake of calculation let us assume that the compound is
an ideal gas at STP.
So that the molar volume is: 1 mole = 22.4 L
<span>density = (44.01 g/mol) * (1 mol / 22.4 L) = 1.96 g/L =
1.96 kg/m^3</span>
Answer:
15000N/m²
Explanation:
Given parameters:
Force exerted by the girl = 450N
Area = 300cm²
Unknown:
Pressure exerted by her feet =?
Solution:
Pressure is the force per unit area on a body;
Pressure =
We need to convert the given area to m²;
10000cm² = 1m²
300cm² =
= 0.03m²
Pressure =
= 15000N/m²
When two bodies interact they apply forces to one another that are equal to magnitude and opposite direction
Answer:
i guess its example of observation
