Pulses A, B, C, and D all travel at 10 m/s on the same string but in opposite directions. The string is depicted at time t=0 in
Anit [1.1K]

(a) The displacement of point P at time t=0.10s is determined as +2cm.

(b) The displacement of point P at time t=0.20s is determined as -2cm.

<h3>What is displacement?</h3>

Displacement is the change in position of an object. It is obtained from the product of velocity and time of motion.

x = vt

<h3>Displacement of the waves after 0.1 s</h3>

x = 10 m/s x 0.1 s = 1 m

Each wave will travel 1 m to the right or to the left, depending on the initial direction.

  • wave B from left will stop at point 0 m
  • wave A from left will stop at point -1 m
  • wave C from right will stop at point 0 m
  • wave D from right will stop at point + 1 m

wave B and C superimposed and the displacement will be between A and D.

Amplitude of A = - 2cm

Amplitude of D = + 4cm

Displacement of point P = 4 cm - 2 cm =  2cm

<h3>Displacement of the waves after 0.2 s</h3>

x = 10 m/s x 0.1 s = 2 m

Each wave will travel 2 m to the right or to the left, depending on the initial direction.

  • wave B from left will stop at point 1 m
  • wave A from left will stop at point 0 m
  • wave C from right will stop at point -1 m
  • wave D from right will stop at point 0 m

Displacement of point P = (amplitude B + amplitude C) + (amplitude A + amplitude D)

Displacement of point P= (2cm - 2cm) + (2 cm - 4cm)= -2cm

A chemist measures the amount of bromine liquid produced during an experiment. She finds that 496g of bromine liquid is produced
vfiekz [6]

Answer:

6.208 mol

Explanation:

Mass of Bromine Liquid = 496g

Number of moles = ?

Relationship between number of moles and mass is given as;

Number of moles = Mass / Molar mass

Molar mass of Bromine = 79.9g

Number of moles = 496 / 79.9 = 6.208 mol
