Hydraulic jacks, automobile brakes and even the lift generated on airplane wings can be explained using Pascal's principle. Pascal's principle is based on the idea that fluids at rest are incompressible, allowing very large forces to be transmitted with the application of a smaller force.

Answer:

Pascal's law states that a change in pressure at any point in an enclosed fluid is transmitted equally throughout the fluid.

Explanation:

Applications of Pascal's law include

>The hidden standard of the water powered jack and pressure driven press.  

>Power intensification in the slowing mechanism of most engine vehicles.  

>Utilized in artesian wells, water pinnacles, and dams.  

>Scuba jumpers must comprehend this rule. At a profundity of 10 meters submerged, pressure is double the environmental weight adrift level, and increments by around 100 kPa for each expansion of 10 m depth.[5]  

>Generally Pascal's standard is applied to bound space (static flow), however because of the consistent flow process, Pascal's rule can be applied to the lift oil instrument (which can be represented as a U tube with pistons on either end).

Without Pascal's law, none of the above could be possible.

An 85 kg man stands in a very strong wind moving at 15 m/s at torso height. As you know, he will need to lean in to the wind, an
PSYCHO15rus [73]

Answer:

  a) T= 72.9 Nm

  b)      \Theta = 5 \textdegree

Explanation:

From the question we are told that

Mass 85kg

Speed 15m/s

Center of gravity 1.0m

Cylinder 50 cm wide and 90 cm long centered 1.2 m above the ground

a)Generally equation for force is given by

   F = 0.5 p A v^2

Mathematically solving for force exacted

   F = 0.5*1.2*0.9*0.5*15^2

   F= 60.75 N

Mathematically solving for torque

Torque,

    T = r * F

    T=1.2*60.75

   T= 72.9 Nm

b)Generally in solving for \theta

   Tan\theta = Torque/(Mass * Gravity)

   Tan\theta = (72.9)/(85 * 9.8)

     \Theta = 5 \textdegree

What is the G.P.E of 675 newtons on 26000 meter mountain
vagabundo [1.1K]
GPE=mgh, where m=mass, g=acceleration due to gravity, h=height
We have a force of 675N already, so mg=675N

<span>GPE=mgh=675(26000)=17.55x10^6J</span>

The change in momentum of an object is equal to the Question 4 options: Force acting on it times its velocity. impulse acting on
lesya [120]

Answer:

impulse acting on it

Explanation:

The impulse is defined as the product between the force applied to an object (F) and the time interval during which the force is applied (\Delta t):

I=F\Delta t

We can prove that this is equal to the change in momentum of the object. In fact, change in momentum is given by:

\Delta p = m \Delta v

where m is the mass and \Delta v is the change in velocity. Multiplying and dividing by \Delta t, we get

\Delta p = m \frac{\Delta v}{\Delta t} \Delta t

and since \frac{\Delta v}{\Delta t} is equal to the acceleration, a, we have

\Delta p = ma \Delta t

And since the product (ma) is equal to the force, we have

\Delta p = F \Delta t

which corresponds to the impulse.
