Answer:Distance=6.67 (rounded)
Explanation: Work = Force x Distance.
100 Joules of work= force of 15 N x Distance (?)
The work equation given above can be rearranged to find force or distance if the other variables are known:
Distance=Work / force
Distance=100Joules/15 N
Distance=6.67 (rounded)
Answer:
see explanation
Explanation:
Given quantities:
radius = r = 0.0558 [m]
current = I = 0.23 [A]
Now we solve this by obtaining the torque acting on the dipole
We obtain the magnetic moment vector M, first, |M| is defined as 
, where A is the cross-section area of the loop which is ![A = \pi r^2=\pi (0.0558)^2= 0.00978 [m^2]](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2%3D%5Cpi%20%280.0558%29%5E2%3D%200.00978%20%5Bm%5E2%5D)
then
![|M| = 0.23*0.00978 = 0.00225 [A/m^2]](https://tex.z-dn.net/?f=%7CM%7C%20%3D%200.23%2A0.00978%20%3D%200.00225%20%5BA%2Fm%5E2%5D)
now the magnetic moment vector is equal to the magnetic dipole moment vector multiplied the magnitude we just obtained 
Now:
a )
b) 
a) the determinant gives us:
b) the dot product gives = ![-1*-7.2*10^{-6} = 7.2*10^{-6}[J]](https://tex.z-dn.net/?f=%20-1%2A-7.2%2A10%5E%7B-6%7D%20%3D%207.2%2A10%5E%7B-6%7D%5BJ%5D)
Explanation:
Plate tectonics is the idea that the earth's outer solid crust (the lithosphere) is fragmented into a few dozen "plates" that pass relative to each other across the earth's surface, like ice slabs on a lake.
A scientist named Alfred Wegener in 1915 proposed that the continents rammed through ocean basin crust, which would clarify why the shapes of many coastlines (such as South America and Africa) seem to match together like a puzzle.
Answer: H
Explanation:
When beavers dam a stream they slow the movement of water. Behind the beaver dam, a pond of still water is formed. This pond is then colonized by animals and plants that typically live in lakes rather than streams.
