Is potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system
Answer:
B. Axial stress divided by axial strain
Explanation:
Elasticity:
It is the tendency of an object to deform along the axis when an opposing force is applied without facing permanent change in shape.
Plasticity:
When an object crosses the elasticity limit, it enters plasticity where the change due to stress is permanent and the object might even break.
Yield strength:
Yield strength is the point of maximum bearable stress that indicates the limit of elasticity.
Our case:
As the stress applied is less than the yield strength, the rod is still in the elasticity state and its modulus can be calculated.
Modulus of Elasticity = Stress along axis/Ratio of change in length to original length
Axial strain is basically the ratio of change in length to original length.
So, Modulus of Elasticity = Axial Stress/ Axial Strain
A. because as the merry-go-round spins the child accelerates towards the center of the merry-go-round at a uniform rate.
This should be dust and gas
If Adam is pulling with a pulling force of 120N, and the nets pulling force is 200N, and they are both going north, then that means that Krystal would have a a pulling force of 80N north, as 200N- 120N is 80N. She would be pulling north because she is on the same side as Adam, helping to pull the sled upwards.
-Hope this helps! xo
