What is the mechanism of hydraulic machine ​

Physics
1 answer:
nata0808 [166]2 years ago
5 0

Answer:

The hydraulic press allows the applied force (F1) to be converted into a higher force (F2) along some path as many times as the surface of the driven hydraulic cylinder (A2) is larger than the surface of the driving hydraulic cylinder (A1). The hydraulic press works on the basis of Pascal's law, which reads: External pressure is transmitted through the fluids equally in all directions.

A cruise ship made a trip to Guam and back. The trip there took 12 hours and the trip
Alecsey [184]

Answer:

The average speed is 8.0 km/h

Explanation:

We use the data for the return journey to calculate the distance travelled using the constant velocity equation:

s  =  v  t  =6*4=24km

 

Note I didn't change any units so the answer comes out in kilometres.

Now use the distance and time taken to travel to Guam to find the average speed:

v=st=24/3=8.0km/h

20. GP A sinusoidal wave traveling in the negative x direction (to the left) has an amplitude of 20.0cm, a wavelength of 35.0cm,
umka21 [38]

The angular frequency of the wave is determined as 75.4 rad/s.

<h3>What is wave function?</h3>

A wave function is a mathematical equation for the motion of the wave.

y(x, t) = A sin(kx + ωt + Φ)

where;

  • ω is angular speed
  • k is angular wavenumber
  • Φ is phase angle

<h3>What is angular frequency?</h3>

The angular frequency is the angular displacement of any wave element per unit of time or the rate of change of the waveform phase.

<h3>Angular frequency</h3>

ω = 2πf

ω = 2π(12)

ω = 75.4 rad/s

Thus, the angular frequency of the wave is determined as 75.4 rad/s.
