Answer:
explanations below
Explanation:
From the attached document, it can be seen that Stations 2 and 3 are further away from the epicenter unlike stations 1 and 4. Stations 2 and 3 are likely going to record fewer waves than the others because as the wave travel such distances, part of it are bent by the earth’s interior and some of the materials in earth also reflect some of the waves.

Answer:
The magnetic field at the center of a circular loop is .
Explanation:
Given that,
Radius = 4.0 cm
Current = 2.0 A
We need to calculate the magnetic field at the center of a circular loop
Using formula of magnetic field
Where, I = current
r = radius
Put the value into the formula
Hence, The magnetic field at the center of a circular loop is .
