Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when sp
yKpoI14uk [10]

Answer

given,

difference between the two consecutive maximum

λ = 0.870 - 0.540

λ = 0.33 m

speed of sound = 340 m/s

b) frequency of the sound

v = f x λ

340 = f x 0.33

f =\dfrac{340}{0.33}

    f = 1030.3 Hz

a) phase difference

  the expression of phase difference is given by

   \phi = \dfrac{2\pi}{\lambda}\ \delta

   \delta = \Delta x - \lambda

   \delta = 0.540 - 0.33

   \delta = 0.21\ m

now,

   \phi = \dfrac{2\pi}{\lambda}\ \times 0.21

   \phi = \dfrac{2\pi}{0.33}\ \times 0.21

   \phi = 3.99 rad

Is your increase in gravitational potential energy the same in both cases? When Climbing a mountain on a zigzag path and on a st
baherus [9]

Answer:

The increase in gravitational potential energy is the same in both cases

Explanation:

It is easier to climb a mountain in a zigzag way rather than climbing on a straight line but since the distance is the same ( vertical height ) , mass and gravity is the same. Hence the increase in gravitational potential energy is the same in both cases.

gravitational potential energy = mgh ( same in both cases )

m = mass

g = acceleration due to gravity

h = distance ( vertical height )
