What are the five basic postulates of kinetic-molecular theory?
lesantik [10]

Explanation:

The five basic postulate of kinetic molecular theory includes:

1) All gases consist of large amount and numbers of tiny particles that are far apart from each other and also relative to their size.

2) The collisions between gas particles and gas particles against container walls is refer to as  elastic collision.

3) All gas particles are in a continuous random and rapid motion. They possess kinetic energy which is energy of motion.

4) There are no attractive force between gas particles.

5) The temperature of a gas depends on the average kinetic energy of the gas particle.

The legs of a weight lifter must ultimately support the weights he has lifted. A human tibia (shinbone) has a circular cross sec
Sergio039 [100]

Answer:

249003822308.05008 N

Explanation:

F = Force

\sigma = Breaking stress of bone = 150 MPa

d_2 = Outer diameter = 3.6 cm

d_1 = Inner diameter = 2.3 cm

Area of the bone is assumed to be a hollow cylinder

A=\dfrac{\pi}{4}(d_2^2-d_1^2)

Stress is given by

\sigma=\dfrac{F}{A}\\\Rightarrow F=\sigma A\\\Rightarrow F=\dfrac{150\times 10^6}{\dfrac{\pi}{4}(0.036^2-0.023^2)}\\\Rightarrow F=249003822308.05008\ N

The maximum weight the person can lift without breaking his legs is 249003822308.05008 N
