An effective early childhood curriculum can be learning how to read and write. Without learning how to read, we wouldn’t be able to communicate through this app, or through online school. We wouldn’t know directions, and we wouldn’t be able to enjoy stories. If we didn’t know how to write, I would not be able to help you figure out the answer to this problem, and your teacher wouldn’t be able to grade anything. Think about it, you ir entire education is based of being able to read and write.


Hope this helps :)

A long wire carries a current density proportional to the distance from its center, J=(Jo/ro)•r, where Jo and ro are constants a
IgorC [24]

Answer:

B = \mu_0(\frac{1}{3} \frac{J_0}{r_0} r^2)

Explanation:

As the current density is given as

J = \frac{J_0}{r_0}r

now we have current inside wire given as

i = \int J(2\pi r)dr

i = \int \frac{J_0}{r_0} r(2\pi r)dr

i = 2\pi \frac{J_0}{r_0} \int r^2 dr

i = \frac{2}{3} \pi \frac{J_0}{r_0} r^3

Now by Ampere's law we will have

\int B. dl = \mu_0 i

B. (2\pi r) = \mu_0(\frac{2}{3} \pi \frac{J_0}{r_0} r^3)

B = \mu_0(\frac{1}{3} \frac{J_0}{r_0} r^2)

Calculate the magnitude of the angular momentum of the earth due its daily rotation about its own axis
ioda
L=Iw
I_{earth} =  \frac{2}{5} r^{2}m= \frac{2}{5} (6371000^2m)(5.97*10^{24}kg)=9.71*10^ {37}
L_{earth}=Iw=(9.71*10^ {37})(7.27*10^{-5})=7.07*10^{33}<span>[/tex]</span>

Answer:

the answer is false :)

Explanation:

Science is based on theories and tests, if someone has a theory they will test and if it is correct yippie! and if it isn't they will redo the test over until they get it correct or unless it is unsolvable.
