Answer:
No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.
Answer:
C) If an ice cube is placed into a boiling water, then it will melt in less than 2 minutes.
Explanation:
Answer:
distance r from the uranium atom is 18.27 nm
Explanation:
given data
uranium and iron atom distance R = 44.10 nm
uranium atom = singly ionized
iron atom = doubly ionized
to find out
distance r from the uranium atom
solution
we consider here that uranium electron at distance = r
and electron between uranium and iron so here
so we can say electron and iron distance = ( 44.10 - r ) nm
and we know single ionized uranium charge q2= 1.602 ×
C
and charge on iron will be q3 = 2 × 1.602 ×
C
so charge on electron is q1 = - 1.602 ×
C
and we know F =
so now by equilibrium
Fu = Fi
=
put here k =
and find r
=

r = 18.27 nm
distance r from the uranium atom is 18.27 nm
Answer:
v =163.95 m/s
Explanation:
Given that,
The wavelength of wave, 
Distance covered, 
We need to find the speed of the wave. We know that,
speed = distance/time
So,

So, the speed of the wave is equal to 163.95 m/s.
