For monatomic ideal gas of n particles in volume v which maxwell-boltzmann distribution, find out the speed distribution n(v)dv. n(v)dv represents the number of particles whose speeds are in the range from v to v+dv given einstein solids, the vibrational energy levels as 3. for 2-dimensional are consider the crystalline solid as an assembly of 2n e(j+h, j=0,1,2, 2 distinguishable oscillators (a) calculate the internal energy, u (b) calculate the specific heat at constant volume, c (c) find out helmholtz energy, f (d) calculate the entropy, s

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
