Answer: about 162,000
Explanation: Between 1788 and 1868, about 162,000 convicts were transported from Britain and Ireland to various penal colonies in Australia.
We increased security after 9/11, in airports, schools etc. As and example, your luggage has to be much lighter than it was before 9/11.
I think we should have a specific group that checks everyone's history and record if they have one, before they enter the plain, my example is 9/11, if they would have done that they would have known that they were not American residents and the bendanes they wore was a cult.
They commit acts of terrorism believing that killing themselves and you that they are going to heaven. And I think they should be 1. wiped off the planet, for the simple fact that they will never change so we have to try to get rid of them, or 2. lock up everyone of them we can in a supermax prison so they can never see daylight again.
I hope this helps!
Answer: a water filled cover.
Explanation:The cooling down process could take an hour or two. The early machine guns had to be cooled down using a water filled cover.
The total pressure the submarine must withstand is 1301 kPa.
<h3>What is pressure?</h3>
Pressure refers to the force exerted by one object on another. In this case, the force exerted by the water on the submarine. This factor is often measured in kilopascals or kPa.
<h3>How to calculate the absolute pressure?</h3>
To calculate the absolute pressure you will need to use the following formula:
- the pressure exerted by the atmosphere + pressure exerted by water.
The pressure exerted by the atmosphere:
- At 0 meters above sea level, the pressure is 1atm or 101 kPa.
The pressure exerted by the water:
- The pressure increases by 100 kPa for every 10 meters.
- 120 meters / 10 meters = 12 x 101kPa = 1200 kPa
Finally, add the results
- 1200 kPa + 101 kPa= 1301 kPa
