Explanation:

a couple is a system of forces with a resultant moment but no resultant force. A better term is force couple or pure moment. Its effect is to create rotation without translation, or more generally without any acceleration of the centre of mass.

The force exerted on a given area.

Option B is the right option.

Explanation:

<h2>About pressure</h2>

Pressure is defined as force acting per unit area. It's SI unit is Pascal or N/m^2.

Formula to find pressure is:

$\frac{thrust(f)}{area(a)}$

The force acting perpendicular on a surface is called the thrust. It is a vector quantity.

One Pascal pressure

One Pascal pressure is defined as the pressure exerted in a surface of area m^2 by the thrust of 1 N

Hope this helps ..

Explain the difference between balanced forces and action and reaction forces.

Monica [59]

Action-reaction forces act on different objects; balanced forces act on the same object. Balanced forces can result in acceleration, action-reaction forces cannot. ... Newton's Third Law of Motion does not apply to balanced forces.

A research vessel is mapping the bottom of the ocean using sonar. It emits a short sound pulse called "ping" downward. The frequ

Elena L [17]

Answer:

The ocean is 6485.6m deep when measured from the vessel

Explanation:

v=1474m/s

t=8.88s

let d represent distance from the vessel to the ocean bottom.

an echo travels a distance equivalent to 2d, that is to and fro after it reflects from the obstacle.

$velocity=\frac{distance}{time}\\ v=\frac{2d}{t} \\vt=2d\\d=\frac{vt}{2}$
