Answer:
gas
Explanation:
this is bcz they have higher kinetic energy compared to liquids and gases
Your center or gravity helps your balance because either it will help younot fall or it wont some people are just clusmy
Answer:
The correct answer is 231 Mpa i.e option a.
Explanation:
using the equation of torsion we Have

where,
= shear stress at a distance 'r' from the center
T = is the applied torque
= polar moment of inertia of the section
r = radial distance from the center
Thus we can see that if a point is located at center i.e r = 0 there will be no shearing stresses at the center due to torque.
We know that in case of a circular section the maximum shearing stresses due to a shear force occurs at the center and equals

Applying values we get

I don’t worry wewwwww it is a good time to get it done lol lol i don’t worry about it lol lol i lol
