Answer:
0.22 b
Explanation:
Quadrupole moment of the nucleon is,
![Q=-\frac{2j-1}{2(j+1)}\frac{3}{5}R^{2}](https://tex.z-dn.net/?f=Q%3D-%5Cfrac%7B2j-1%7D%7B2%28j%2B1%29%7D%5Cfrac%7B3%7D%7B5%7DR%5E%7B2%7D)
And also,
![R^{2}=R^{2} _{0}A^{\frac{2}{3} }](https://tex.z-dn.net/?f=R%5E%7B2%7D%3DR%5E%7B2%7D%20_%7B0%7DA%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
And, ![R _{0}=1.2\times 10^{-15}m](https://tex.z-dn.net/?f=R%20_%7B0%7D%3D1.2%5Ctimes%2010%5E%7B-15%7Dm)
Now,
![Q=-\frac{2j-1}{2(j+1)}\frac{3}{5}R^{2} _{0}A^{\frac{2}{3} }](https://tex.z-dn.net/?f=Q%3D-%5Cfrac%7B2j-1%7D%7B2%28j%2B1%29%7D%5Cfrac%7B3%7D%7B5%7DR%5E%7B2%7D%20_%7B0%7DA%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
For Bismuth
and A is 209.
![Q=-\frac{2\frac{9}{2} -1}{2(\frac{9}{2} +1)}\frac{3}{5}(1.2\times 10^{-15}) ^{2}(209)^{\frac{2}{3} }\\Q=0.628\times 35.28\times 10^{-30} \\Q=22.15\times 10^{-30} m^{2} \\Q=0.2215\times 10^{-28} m^{2} \\Q=0.22 barn](https://tex.z-dn.net/?f=Q%3D-%5Cfrac%7B2%5Cfrac%7B9%7D%7B2%7D%20-1%7D%7B2%28%5Cfrac%7B9%7D%7B2%7D%20%2B1%29%7D%5Cfrac%7B3%7D%7B5%7D%281.2%5Ctimes%2010%5E%7B-15%7D%29%20%5E%7B2%7D%28209%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D%5C%5CQ%3D0.628%5Ctimes%2035.28%5Ctimes%2010%5E%7B-30%7D%20%5C%5CQ%3D22.15%5Ctimes%2010%5E%7B-30%7D%20m%5E%7B2%7D%20%5C%5CQ%3D0.2215%5Ctimes%2010%5E%7B-28%7D%20m%5E%7B2%7D%20%5C%5CQ%3D0.22%20barn)
Therefore, the expected value of quadrupole is 0.22 b which is quite related with experimental value which is 0.37 b
The acceleration of the object which moves from an initial step to a full halt given the distance traveled can be calculated through the equation,
d = v² / 2a
where d is distance, v is the velocity, and a is acceleration
Substituting the known values,
180 = (22.2 m/s)² / 2(a)
The value of a is equal to 1.369 m/s²
The force needed for the object to be stopped is equal to the product of the mass and the acceleration.
F = (1300 kg)(1.369 m/s²)
F = 1779.7 N
Initial velocity u = 50 miles/hour
acceleration a = 10 miles/hour
Time t = 2 hours
Distance travelled S = ut + (at^2)/2
Substituting the values in the second equation of motion,
S = 50*2 + (10 * 2 *2)/2
S = 100 + 20
S = 120 miles
Therefore the distance travelled by the car in the next two hours is 120 miles
Answer:
E=72000J or 72kj
Explanation:
The formula is E=pt you need to convert your t from minutes to seconds before proceeding
Weight = (mass) x (gravity)
120 N = (mass) x (9.8 m/s²)
Mass = (120 N) / (9.8 m/s²)
Mass = 12.24 kg (B)
