2. Solve the equation x16 - 2x15 - x14 - 4x13 – x12 - 2x11 - x10 = 0 in the real number system.
Ox=-1 with multiplicity 2. x=1 with multiplicity +
Dy=0 with multiplicity 10. x = -1 with multiplicity 3. = 1 with multiplicity 3
Ox=0 with multiplicity 10, x=-1 with multiplicity 2. x = 1 with multiplicity 4
Ox=0 with multiplicity 10.x=-1 with multiplicity 4.x = 1 with multiplicity 2

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

the temperature of the gas, in k, not celsius.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
