It depends most on the temperature of the gas.
Answer:
Star A
Explanation:
μ = proper motion = 1 arcsecond per year
r = 20 light-years = Distance
Transverse velocity
V = 1.45 × μ × r
⇒ V = 1.45 × 1 × 20
⇒ V = 29 km/sec
When r = 10 light-years
V = 1.45 × 1 × 10
⇒ V = 14.5 km/sec
∴ Star A which is 20 light-years from Earth is moving faster compared to Star B which is 10 light-years from Earth.
Well if we are talking about the same psychopaths then they are people who will stop at nothing to commit crimes is the way I define them
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
