 Write the Wiedemann Franz law.

A planet of mass 1.000 × 10²⁶ kg, has a moon of mass 2.100 × 10²² kg and orbital radius 3.550 × 10⁵ km. The orbit of the moon is assumed to be circular.

Determine the distance, from the centre of the planet, the point at which the resultant gravitational field is zero.

Q3: A spring is mounted linear ,by attaching a spring balanced to

the free end and pulling sideways, we determine that the force of

(4 N ) causes a displacement of 0.02 m .we attach a 2 kg body to

the end ,pull it a side distance of 0.04 m and release it .Find :

1) the force constant of the spring ?

2) the period and frequency of vibration ?

3) compute the maximum velocity attained by the vibrating

body ?

I've been told many times that electrons are indivisible particles, I've come up with a thought experiment that tells me that is wrong, electrons have fundamental components creating them. I'd like to know how we know that the standard model particles are indivisible??

Germainium a 200.0 K has 1.16×10^10 free electrons per atom. If you wanted to have 2×10^3 as many electrons from arsenic doping as thermally free electrons in a Germainium semiconductor, how many arsenic atoms should there be per Germainium atom ?

Hello.I was told that a parllel universe can share the same dimension

 Three spin less non-interacting distinguishable particles, with respective masses  𝑚1, 𝑚2, and 𝑚3 in the ratio 𝑚1: 𝑚2: 𝑚3 = 1: 2: 3, are subject to a common infinite  square well potential of width L in one spatial dimension. Determine the energies and the corresponding wave functions in the lowest two energy states of the system.

A system can take only 3 different energy states E1=0j,E2=1.38j,E3=2.76. These states occur 2,5,4, different ways respectively.deduse the probability that at 100k of the system.a one of microstate of E3.in one ground state energy E1.

The current position of the harmonic oscillator is given by the relation 

x(t)=(0,3m)cos(πt/2).Time t is expressed in seconds. Find the period of the oscillator.
