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.

-- Free neutrons collide with Uranium nuclei.
If one is absorbed, then
-- the Uranium nucleus falls apart,
producing
-- smaller nuclei,
-- energy,
and
-- more free neutrons.
As per the given question,
Focal length of the concave mirror(f)=0.25m
position of virtual image form the mirror (v)=0.04m
let the position of the object from the concave mirror (u)=?
u=3.44cm
Answer:
t = 4.0 min
Explanation:
given data:
diameter of rod = 2 cm
T_1 = 100 degree celcius
Air stream temperature = 20 degree celcius
heat transfer coefficient = 200 W/m2. K
WE KNOW THAT
copper thermal conductivity = k = 401 W/m °C
copper specific heat Cp = 385 J/kg.°C
density of copper = 8933 kg/m3
charateristic length is given as Lc
Biot number is given as 
Bi = 0.0025
As Bi is greater than 0.1 therefore lumped system analysis is applicable
so we have
............1
where b is given as
b = 0.01163 s^{-1}
putting value in equation 1
solving for t we get
t = 4.0 min
