At a depth of 10 m, the manatee's neutral buoyancy keeps it at the same level in water as if there were no air inside its lungs. However, because more air is now contained in the manatee's lungs than before it dove, its weight increases by 9.81 kg and therefore it accelerates downwards (due to momentum). This downward acceleration continues until equilibrium is reached and then ceases due to gravity pulling on both objects equally.
As a result, the manatee now becomes negatively buoyant and must rise to compensate.
<h3>What does it mean when something has neutral buoyancy?</h3>
When something has neutral buoyancy, it is not affected by the weight of anything above or below it.
This means that objects with neutral buoyancy will stay in place regardless of how high or low they are located in a liquid medium.
Examples of things with neutral buoyancy include air balloons and swimming caps.

Answer:
Explanation:
a ) Let T be tension in the horizontal cable .
Taking torque about hinge of weight and tension
45000 x 7 x cos37 = 3.5 sin 37 x T
T = 119431 N
b ) If R be the reaction force on the hinge
R sin 37 = 45000 ( vertical force balancing each other )
R = 74775 N
c ) The direction of R will be along the bridge
d ) Moment of inertia of bridge
I = Ml² / 3 = (45000 / 9.8 ) x 14² / 3
= 300000.
When cable breaks , the weight creates a torque about the hinge will creates angular acceleration
Torque by weight about the hinge
= 45000 x 7 x cos 37
= 251570
angular acceleration = torque / moment of inertia
= 251570 / 300000
= .84 radian / s²
When it has been proven by science to be true.

Just because u have gay parents doesnt mean theyre bad lol XD
Answer:
Explanation:
25) Electrical -> thermal. In a toaster, there is a resistance through which current flows. Due to the Joule effect, the current flowing through the resistor causes an increase of temperature of the resistor itself, therefore the energy of the current (electrical) is converted into thermal energy, which is then used to heat the toast.
