Answer:
For outer points of shell

Now for inner point of shell

Explanation:
As we know that out side the shell electric potential is given as

inside the shell the electric potential is given as

now we know the relation between electric potential and electric field as

so we can say for outer points of the shell



Now for inner point again we can use the same



I don't really know but I don't think you can... I can't explain it either. Sorry im no help

Answer:
time is 0.5660 s
and time is - 3.62431 s
Explanation:
velocity u = 15 m/s
height s = 10 m
acceleration due to gravity g = –9.8 m/s²
to find out
time
solution
we will apply here distance equation that is
s = ut - 1/2× gt² ...........1
here put all these value and get time t
here s is height and g is -9.8
so
s = ut - 1/2× gt²
10 = 15t - 1/2× (-9.8)t²
10 = 15t + 4.9t²
solve it we get t
t = 0.56630 and -3.62431
so time is 0.5660 s
and time is - 3.62431 s
<h3><u>Answer;</u></h3>
travel through solids
P waves and S waves are alike in that they<u> both travel through solids</u>.
<h3><u>Explanation;</u></h3>
- <em><u>P-waves and S-waves are types of seismic waves.</u></em> These waves are produced during an earthquake, that transmit energy released around the earth.
- <u><em>P-waves travel the fastest and also travel through solids, liquids and gases. </em></u>They are push and pull waves and thus they cause rock particles to move back and forth.
- <u><em>S-wave son the other hand arrive at a given point after the p-waves. They do not travel as fast as P-waves. They travel through solids but not in liquids and gases.</em></u> S -waves cause the rocks to move side to side.
