Answer:

Material's density

Explanation:

Seismic waves travel at different rates of speed based on a material's density. Hopefully, you understand that the Earth has three main layers: the crust, mantle, and core. Earthquake waves move faster through solids.

In the return stroke of a typical lightning bolt, a current of 7.01×10^4 A (70.1 kA). exists for 20 μs. How much charge is trans

fenix001 [56]

Answer:

Charge, q = 1.402 C

Explanation:

Given that,

Current from lightning bolt, $I=7.01\times 10^4\ A$

Time, t = $t=20\ \mu s=2\times 10^{-5}\ s$

Let q is the charge transferred in this event. We know that the total charge divided by time is called current. Mathematically, it is given by :

$I=\dfrac{q}{t}$

$q=I\times t$

$q=7.01\times 10^4\times 2\times 10^{-5}$

q = 1.402 C

So, 1.402 coulomb of charge is transferred in this event. Hence, this is the required solution.

Which of the following four circuit diagrams best represents the experiment described in this problem?

Valentin [98]

We don't see any circuit diagrams.

This worries us for a few seconds, until we realize that we don't know anything about the experiment described in the problem either, so we don't have to worry about it at all.
