Answer:
t = 3w/gk
y = w²/gk²(2+e^-gkt/t)
Explanation:
The detailed step by step solution can be found in the attachment below.
Vt = W/k. It is the velocity of the body when the drag force = the weight of the particle.
I steps have been explaine6in the attachments below.
Answer:
Option C
80 years
Explanation:
<em>From Scientific records, the rate of movement of the plate is 0.025 meters</em>
Since the fault moves at the rate of 2 meters per year, to obtain the number of years it will takes to produce an earth quake, we will have to divide the rate of movement of the fault by the rate of movement of the plate.
Number of years for earthquake = 
= 80 years.
Hence, it will take 80 years to produce one big earthquake.
Answer:
Explanation:
Let equal mass of Ne and Kr be m gm
no of moles of Ne and Kr will be m / 20 and m / 84 ( atomic weight of Ne and Kr is 20 and 84 )
Let the pressure and volume of both the gases be P and V respectively .
The temperature of Ne be T₁ and temperature of Kr be T₂.
For Ne
PV = (m / 20) x R T₁
For Kr
PV = (m / 84) x R T₂
T₁ / T₂ = 84 / 20
We know that
average KE of an atom of mono atomic gas = 3 / 2 x k T
k is boltzmann constant and T is temperature .
KEKr/KENe = T₂ / T₁
= 20 / 84
Answer:
coal, oil and natural gas.
Explanation:
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
