there are 28 neutrons present
Given that the arc length is:
s = ∫ √[1² + (dy/dx)²] dx
<span>So arc length between the two points is then: </span>
<span>s = 2*20sinh(x/20)
= 40sinh(x/20) </span>
<span>The straight distance between the two points is : d = 2x </span>
<span>So, x = d/2.
= 40/2
= 20 m </span>
<span>Plug this into the arc length equation to get:
s = 40sinh[20/20)]
=40* ½ (e - 1/e) </span>
<span> = 47 m</span>
We're u can never put it back together
<span>10.7 hours
Since we've been told that we have a speed of 1 km/h and a width of 0.5 meters that means that after 1 hour, we can mow a path 0.5 m wide and 1000 m long for a total area of 1000 m * 0.5 m = 500 m^2/hr. Now let's calculate the area of that football field.
360 ft / 3.281 ft/m * 160 ft / 3.281 ft/m = 5350.692864 m^2
Now let's divide that area by the 500 m^2 calculated earlier to see how many hours it will take.
5350.692864 m^2 / 500 m^2/hr = 10.70138573 hr
So it would take about 10.7 hours to mow the football field.</span>
Melting is most affected by pressure i think
