When more than one wave is in the same location at the same time, then there is _____ between the waves?
igor_vitrenko [27]
The sentence can be completed as follows:
"<span>When more than one wave is in the same location at the same time, then there is interference between the waves"

In fact, when there are two or more waves in the same location at the same time, their amplitude sum together. The two extreme possibilities are:
- costructive interference: the two waves arrive on phase at the same location (=their crests arrive at the same location at the same time). In this case, the amplitudes of the waves sum together and the resultant wave has greater amplitude.
- destructive interference: the two waves arrive out of phase at the same location. In this case, the amplitudes of the two waves cancel out, and the resultant wave has amplitude zero.</span>

Give a real life example in which two objects are moving at a constant speed but have different velocities.
Bad White [126]

Answer:

The planets and moons that orbit in the solar system.

Explanation:

For example the earth moves at 67,000 mph (107,000 km/h), and is constant from the gravitational pull of the sun. The moon orbits at about  2,288 mph (3,683 km/h).  these are both traveling at different velocities but at a constant speed.

Use the information below for the next five questions:
sergey [27]

Answer:  Please see answer in explanation column.

Explanation:

Given that

v≈(331 + 0.60T)m/s

where Temperature, T =  14°C

v≈(331 + 0.60 x 14)m/s

v =331+ 8.4 = 339.4m/s

In our solvings, note that

f= frequency

 λ=wavelength

L = length

v= speed of sound

a) Length of the pipe is calculated using the fundamental frequency formulae that

f=v/2L

Length = v/ 2f

= 339.4m/s/ 2 x 494Hz ( s^-1)= 0.3435m

b) wavelength of the fundamental standing wave in the pipe

L = nλ/2,

λ = 2L/ n

λ( wavelength )= 2 x 0.3435/ 1

= 0.687m

c) frequency of the fundamental standing wave in the pipe

F = v/  λ

= 339.4m/s/0.687m=

494.03s^-1 = 494 Hz

d) the frequency in the traveling sound wave produced in the outside air.

This is the same as the frequency in the open organ pipe = 494Hz

e)The wavelength of the travelling sound wave produced in the outside air is the same as the wavelength calculated in b above = 0.687m

f) To play D above middle c . the distance is given by

L =v/ 2 f

= 343/ 2 x 294

=0.583m
