Now, both the infinite square well system and the simple harmonic oscillator system still have the same value for their ground state energies, eground, but the wavefunctions for both systems are described as a superposition of two energy eigenstates, namely their ground state and their third excited state. what is r(sho/square), the ratio of t1(sho), the minimum time it takes for the probability density rho rho (x, t1,sho) of the simple harmonic oscillator system to return to its original value (rho rho (x,0)) to t1(square), the minimum time it takes for the probability density rho rho (x, t1,square) of the infinite square well system to return to its original value (rho rho (x,0)) ? i. e., r(sho/square) = t1(sho) / t1(square).

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
