Uniform magnetic lines as the name suggests are composed of lines that point to the same direction and of the same magnitude. This means all of these lines exert the same force. Non-uniform relates to different directions of the lines and a varied magnitude.
Answer: a magnetic field is created by moving electric charges
The exact distance from the seismic station to the epicenter is 6000 km.
<h3>
Epicenter of earthquake</h3>
The earthquake's epicenter is the point above the fault location on the earth's surface.
Given that:
A p-wave arrives at 3:00:00 and the s-wave arrives at 3:07:20.
Difference in arrival time = 3:07:20 - 3:00:00 = 7 minutes 20 seconds
From the earthquake time travel graph, a time difference of 7 min 20 sec is at x = 6
The exact distance from the seismic station to the epicenter is 6000 km.

Answer: d= 0.57* l
Explanation:
We need to check that before ladder slips the length of ladder the painter can climb.
So we need to satisfy the equilibrium conditions.
So for ∑Fx=0, ∑Fy=0 and ∑M=0
We have,
At the base of ladder, two components N₁ acting vertical and f₁ acting horizontal
At the top of ladder, N₂ acting horizontal
And Between somewhere we have the weight of painter acting downward equal to= mg
So, we have N₁=mg
and also mg*d*cosФ= N₂*l*sin∅
So,
d=
* tan∅
Also, we have f₁=N₂
As f₁= чN₁
So f₁= 0.357 * 69.1 * 9.8
f₁= 241.75
Putting in d equation, we have
d=
* tan 58
d= 0.57* l
So painter can be along the 57% of length before the ladder begins to slip
