Answer / eugene

Viscosity only applies to fluids, ie. gas and liquid.

However, the nature of viscosity for gas and liquid are
different.

In general, the liquid viscosity is dependent on the
strength of intermolecular attraction. The stronger the
intermolecular attraction, the more the viscous the liquid
is.

In fact, raising the temperature of the liquid decreases
its viscosity. This reflects the viscosity of a liquid is
indeed dependent on the intermolecular attraction.

Answer / chem

As we know what is viscosity is
Viscosty is the resistance offered in the motion of fluid.
it is the ratio of the shear stress and velocity gradient
so it depends on the following factors
shear stress
temperature
velocity

Answer / shrinivas prasad bulusuwar

viscosity is basically the resistance to flow, caused by
friction between two adjacent layers of the fluid.
The bottommost layer offers resistance to the adjacent
layer causing decrease in the velocity of the adjacent
layer.
Also, viscosity is caused due to the inter-molecular forces
of attraction.

QUANTUM COMPUTING - EXAMPLE 32.2 : (a) If | 001 > = | 1 >, | 111 > = | 7 >, find the 2 possible values of ( | 001 > + | 1 > + | 7 > ) ( | 111 > ). (b) In quantum money, a duplicate will have probability P of passing the verification test of a bank, if the total number of photons on the bank note is N. The would be counterfeiter has a probability p of success in duplicating the quantum money correctly for each photon. Guess the relationship of P, p and N as a mathematical formula involving natural logarithm ln.

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.13 : (i) In the Present Value Multiplication Rule, let PV = present value, Ra = interest rate for first discount, A = duration for first discount; Rc = interest rate for second discount, C = duration for second discount. Let PV = [ 1 / (1 + Ra) ^ A ] [ 1 / (1 + Rc) ^ C ] where ^ is the symbol of power : 3 ^ 2 = 3 x 3, 2 ^ 3 = 2 x 2 x 2. (a) For discounts involving 8 % / year for 3 years and 10 % / year for 9 years, find the value of PV. (b) If Re = interest rate for third discount, E = duration of third discount, form a mathematical equation of PV as a function of A, C, E, Ra, Rc, Re. Note : Discounts are available in the purchase of certain biochemical engineering instruments. (ii) Let R = nominal interest rate related to growth rate of money, r = real interest rate related to growth rate of purchase power. If I = inflation, where the unit of R, r and I is %, find the mathematical relatonship of r as a function of R and I.
