Dalton's Atomic Theory had several main points, which are variously grouped into five statements : 1) All matter is made of atoms. 2) Atoms of a given element are identical in size, mass and chemical properties. 3) Atoms of different elements have different masses and properties.
Answer : The correct option is (A) " inverse plot, ".
Explanation:
The atmospheric density is defined as the mass of the per unit volume of the atmosphere of earth. It is measured in .
The atmospheric density on a certain planet is found to decrease as altitude increases. So, there is an inverse relationship between the density and the altitude.
From the attached graph, it is clear that there will an inverse plot for altitude vs atmospheric density.
Let point M in the graph shows 1,291 km. So, density at point M should be in between and less than
So, the density can be
Out of given options, the correct one must be (A) because the point M lies closer to point A.
So, correct option is (A) " inverse plot, ".
Answer: the expression of the mechanical energy for under damped system is;
x(t)=Ae−γ/2tcos(ωdt+ϕ), where ωd=ω02−γ2/4
γ = damping rate, and
ω0 = the angular frequency of the oscillator without damping.
Explanation:
The physical situation in mechanical energy defined through out the world has three possible results depending on the value of a (which is a constant value), which depends on the value of what is under our radical. This expression can either be positive, negative, or equal to zero which will result in overdamping, underdamping, and critical damping, as the case may be.
γ2 >4ω²0 This is the Over Damped case. Here, the system returns to equilibrium by exponentially decaying towards zero, and the system will not pass that equilibrium position more than once.
γ² < 4ω²0 this is the Under Damped case. Here, the system moves back and forth as it slowly returns to equilibrium and the amplitude of the system decreases over time.
Finally, γ² = 4ω²0
This is the Critically Damped case. Here, the system returns to equilibrium very fast without moving back and forth and without passing the equilibrium position at all.
