Answer:

Force has a direct relationship to mass and acceleration. Newton's Second Law, force equals mass times acceleration (F=MA), illustrates their general relationship in an equation.

Explanation:

Relationships to remember:

  • <u>Force</u> and <u>acceleration</u> have a direct relationship, meaning if force increases, acceleration will also increase and vice versa

(Ex: The harder you push a box, the faster it will move)

  • <u>Mass</u> and <u>acceleration</u> have an inverse relationship, meaning if mass increases, acceleration will <em>decrease</em> and vice versa

(Ex: If you add more furniture in the back of a moving company truck, the truck will move slower than it did before the furniture was added)

  • <u>Force</u> and <u>mass</u> have a direct relationship, meaning if mass increases, force will also increase

(Ex: You will need to exert less force to lift a 5-pound weight than a 10-pound weight)

And of course, Newton's Second Law, F=MA sums all of this up in 3 letters and a symbol! If you have any more questions about this problem, please comment on my answer :)

Bezzdna [24]

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.

What are the characteristics of a magnetic force
fomenos

Answer:

Magnetic field lines never intersect each other.

They originates(from north pole) and terminates (to south pole) perpendicularly from/to the surface of magnet. Also magnetic field lines continues through the magnet.

Magnetic field is denser at the pole and becomes less dense as we move away from the poles.

Ballet position which feet turned out
Dmitry [639]
Although all ballet positons involve turned out feet, the simplest one is first position. Heels are touching and toes face out, as far away from each other as possible (close to 180 degrees of rotation).

A bicycle wheel is rotating at 49 rpm when the cyclist begins to pedal harder, giving the wheel a constant angular acceleration
raketka [301]
In 9 sec, it increases the angular velocity by (0.45 x 9) rad/s which will give us 4.05 rad/s 
Now get the angular velocity and divide it 2pi = 4.05 by 2(pi) to give how many revolutions 4.05 rad is equivalent to = 0.6446 rps 
Them, multiply this by 60 to get it from rps to rpm increase (0.6446 x 60)=38.676 rpm 
Add this and the starting revolution frequency of 49 rpm to give: (49 rpm + 38.676 rpm) = 87.6760 rpm
