Answer:
Explanation:
Given data:
Weight W = 16 lb
length l = 6/12 = 0.5 ft
hence, spring constant k = W/l = 16/0.5 = 32 lb/ft
The equation of motion of spring is
the auxiliary equation can be written as
The discriminate of equation is
To get the value of the damping constant,
Answer:
The difference in atomic mass between the two isotopes is 1.002780942 atomic mass unit.
Explanation:
For an isotope-I (heavier)
Mass of an isotope-I=M
Number of neutrons = n+1
Number of protons = p
For an isotope-II
Mass of an isotope-II=M'
Number of neutrons = n
Number of protons = p
Difference in binding energy:
(general binding energy expression)
Binding energy difference between two isotopes:
..(1)
B.E-B.E'=5.4810 MeV
Answer:
Fourier's laws
Explanation:
The problem can be solved if Fourier's laws for conductivity are applied as well,
(1)
where
A = heat transfer area (m2, ft2)
k = thermal conductivity of the material (W/m.K or W/m oC, Btu/(hr oF ft2/ft))
ΔT = temperature difference across the material (K or oC, oF)
s = material thickness (m, ft)
The thermal conductivity of concrete is k= 1.7
Since
1 dollar = 5 Kilowatt hours or 5000 watthours so
Time for 1 dollar = 5000/1256.64 = 3.978 hours or 3 hours 58 minutes

The definition of a scale of 1: 166 will mean that the scale of 1 in the model will be equivalent to 166 times the measurement in the real model, therefore we will have that the height would be 166 times smaller than the 179m given:
The same for the diameter,
The volume of a cylinder is given as
Therefore the volume would be
