Given:

An ideal gas expands at constant pressure:

P = 105 pascals
V1 = 1 m3
V2 = 4 m3

then, the gas is compressed to 1/3 of the pressure and volume 2.50 m3. 

Work at constant pressure:

W = PΔV

W = 105 pascals * (4 m3 - 1 m3)
W = 315 Joules

Work at constant volume is zero.

Particle motion in surface waves is __________ motion.
gulaghasi [49]
<h3>Answer;</h3>

<em>B.)neither longitudinal nor transverse</em>

<h3><u>Explanation;</u></h3>
  • <em><u>Longitudinal waves</u></em> are waves in which the vibration of particles is parallel to the direction of the wave motion.
  • <em><u>Transverse waves</u></em> on the other hand are those waves in which the vibration of particles is perpendicular to the direction of the wave motion.
  • In <em><u>surface waves particles in the medium of transmission move in a circular motion.</u></em> Therefore, they are neither transverse waves nor longitudinal waves.

Distance travel towards north = 3 meter

Distance travel towards south = 6 meter

Find:

Total distance traveled

Computation:

Total distance traveled = Sum of total distance
