Most cats will grow their coat back within 8-12 weeks after shaving. In the case of my cats, it didn't take nearly long enough. Here they are sporting a 'lion cut' they had this summer in an attempt to cut down on the tumbleweeds of fur around the house.

Light travels approximately 982,080,000 ft/s, and one year has approximately 32,000,000 seconds. A light year is the distance li

diamong [38]

So to solve this problem, we must convert units and then cancel units simultaneously:

$(\frac{982,080,000ft}{s})*(\frac{32,000,000s}{1})*(\frac{12inches}{1ft})=3.77x10^{17} inches$

Therefore we know that the distance that light travels in one year is $3.77x10^{17}$ inches.

What is the energy difference between parallel and antiparallel alignment of the z component of an electron's spin magnetic dipo

Readme [11.4K]

Answer:

$\Delta U= 4.8204\times10^{-24} J$

Explanation:

The difference between parallel and anti parallel alignment of the z component of an electron's spin magnetic dipole moment is given by

$U_1-U_2= (-\mu Bcos(\theta_2))-(-\mu Bcos(\theta_1))$

where μ= dipole moment B= strength of magnetic field and θ= angle between direction of magnetic field and dipole

here θ_2 and θ_1 are 180 and 0° respectively.

$U_1-U_2= (\mu B)-(-\mu B)$

$U_1-U_2= 2\mu B$

here μ is bohr magnetron or magnetic moment of an electron = 9.27×10^{-24}

put this value we get

$U_1-U_2= 2\times 9.27\times10^{-24}(0.26)$

$\Delta U= 4.8204\times10^{-24} J$

2 Points<br> How did J. J. Thomson change the atomic model based on his experimental<br> results?

tester [92]

Explanation:

In 1897, J.J. ... Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. Therefore, he proposed a model of the atom which he likened to plum pudding. The negative electrons represented the raisins in the pudding and the dough contained the positive charge.
