Mainly through ideas of Manifest Destiny, the idea that settlers had a god given right to expand with the manifest destiny. after the Louisiana purchase, the US bought land previously owned by the French. We made a purchase of the land, thus it was believed the land was ours, even if others were living on it. plus, the government of the time gave rewards in the land, for fighting the civil war. After the gold rush, more were expanding west for personal wealth, it became a common way of life. Much like the saying if everyone was jumping off a cliff would you, everyone was doing it, so many would not have found it hard to live on land that may have not truly been there's.
When stopped at any light or intersection, you should allow any vehicle approaching the equivalent of at least one city block before entering. Also check to see that no approaching vehicle is travelling at an excessive speed (moving ahead of the other traffic). Once you have made a right turn at an intersection, check your rear view mirror quickly. Sometimes you may have to speed up faster than you thought due to a vehicle approaching faster than you originally thought.
<span>If you stop behind other vehicle in traffic, you should stop so that you can see some road ahead of your vehicle as well as the rear tires of the vehicle ahead of you. This will prevent you from hitting the vehicle ahead of you if you are rear ended.....also check your rear view mirror whenever your foot goes onto the brake......if it is winter, this method will also help prevent you from skidding ......winter driving means you should come off the gas sooner, and brake early and gently and check that rear view mirror! </span>
<span>All the best to you and your driving!</span>
The time it takes for 1g of strontium-90 to decay to 250 mg is; 57.6 years
<h3>What is the half life of an element?</h3>
The formula for half life is;
A(t) = A₀ * (¹/₂)^(t/t_1/2)
Where;
A(t) is amount left after t years
A₀ the initial quantity of the substance that will undergo decay;
t_1/2 is the half-life of the decaying quantity.
We are given;
t_1/2 = 28.8 years
A₀ = 1 g
A(t) = 250 mg = 0.25 g
Thus;
0.25 = 1 * (¹/₂)^(t/28.8)
log 0.25 = (t/28.8) log (1/2)
-0.60206 = (t/28.8) * -0.3010
t = 2 * 28.8
t = 57.6 years
