In physical science, pressure quantifies the amount of force that is applied at a certain area. Mathematically, this can be transformed as,
Pressure = Force / Area
It is also to be noted that force is the product of mass and acceleration due to gravity.
Force = mass x acceleration due to gravity
Substituting,
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, substitute this to the first equation,
Pressure = 3430 N / 1m²
<em>ANSWER: Pressure = 3430 N/m² = 3430 Pa</em>

Answer:
All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.
Explanation:
Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).
Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
Answer:
By correct territorial planning including natural hazards prevention and international accords regarding mitigation and adaptation to climate change.
Explanation:
Natural hazards cant be controlled, we cannot know for sure when an earthquake will occur and an eruption cannot be stopped, but there are still things societies can do to prepare and increase the resilience towards this kind of riks.
Trough territorial planning (if done correctly) societies can prepare well, for example, a city located at a high-risk zone of volcano eruption can set an alarm system to alert citizens to when it would be safe to leave the area. A seismic center can be installed to study the tectonic activity and establish high-risk zones.
Regarding climate change, there needs to be an integration of the different countries to the international accords toward climate change so that natural hazards can be mitigated no only locally but globally.
If done correctly estates can receive the impact of a natural hazard and still function correctly. Making high amounts of preparations and funding natural risk mitigation is justified if we look back at past catastrophes such as Katrina Hurricane or Haiti Earthquake and quantify the damage done.
