The creation of approximately ten million refugees from 1947-48 was a result of World War II.
World War II brought destruction of lot of countries, millions of people lost their homes that were flattened with the ground, the economies were destroyed and on the verge of bankruptcy, so millions of people left their countries in search for better life (or rather just normal life).

Analysis of a rock sample that it contains 6.25% of its original uranium-235. How old is the rock? How do you know?
Andrews [41]

Answer:

The age of the rock = 2800.6 million years = 2.8 billion years.

A simple method of analysis similar to Carbon dating is used to obtain the required age of the rock. Radioactive substances decay according to first order reaction kinetics. So, plugging all the required parameters into the general equation for amount of substance left in a first order decay gives us the age of the rock.

Explanation:

Half life of Uranium-235 = 700 million years (from literature)

The decay of radioactive substances follow first order reaction kinetics.

The general equation is given as

A(t) = A₀ e⁻ᵏᵗ

A(t) = Amount of radioactive substance left after a particular time = 6.25%

A₀ = initial amount of radioactive substance = 100%

t = time that has passed since the beginning = age of the rock = ?

k = decay constant

The decay constant is related to the half life (T) through the relation,

k = (In 2)/T

k = (0.693/700) = 0.00099 /million years

A(t) = A₀ e⁻ᵏᵗ

6.25 = 100 e⁻ᵏᵗ

0.0625 = e⁻ᵏᵗ

In e⁻ᵏᵗ = In 0.0625 = -2.7726

-kt = - 2.7726

t = (2.7726/0.00099) = 2800.6 million years

t = 2.8 billion years.

Hope this Helps!!!

You are steaming across the Atlantic Ocean on a large cruise ship. What happens to your weight as the ship leaves the deep water
Scorpion4ik [409]

Answer:

The shallow water and proximity of the sides of the channel effects the ship navigating through the restricted waters. ... This decreases the upward pressure on the hull, making the ship sink deeper in the water than normal and slowing the vessel.
