Is the component perpendicular to the surface on contact of the contact force <span />
2- Metal
explanation
metal is the only conductor listed
The weightiness of the added
water displaced is equivalent to the joined weight of the two extra people who come
to be into the boat:
<span>m water g = 2 x 690 N</span>
<span> =
1,380 N</span>
<span>
</span>
The mass of the water displace
is then
<span>m water g = 1,380 N</span>
<span> = 1,380 N / 9.8 m/s^2</span>
<span> = 141 kg</span>
<span>
</span>
Compute the calculation for
density for the volume of water displace and practice this outcome for the mass
of the water displace to get the answer:
<span>p water = mass of water / volume of water</span>
<span>
</span>
<span>volume of water = mass of water / p water</span>
<span> = 141 kg / 1000 kg /m^3 eliminate
kilogram</span>
<span> = 0.14 m^3 the additional volume
of water that is displaced</span>
<h2>
Answer</h2>
The answer is 29495.3 kg
<h2>
Explanation</h2>
As we know, the Newton's Second Law of Motion
The F exerted by catapult = 9.35 * 
The Time is = 2.10 s
Velocity of the catapult = 240 km/h = 66.6 m/s (240*1000 m /3600 s)
The mass of jet = ?
First detrmine the acceleration as
{/tex}Acceleration = Velocity/Time {/tex}
Rearrange the formaula as
The mass will be 29495.3 kg
Answer:
I would say its a deep ocean trench
Explanation:
This is because deep ocean trenches are found at the deepest part of the ocean and also at Pacific ocean margins or Rim where subduction usually occurs and Aleutian islands are part of the Pacific Rim
