To solve this problem we will apply the given relationship between wavelength, speed and frequency as well as the use of kinematic equations of motion description.
The wavelength is directly proportional to the speed and inversely proportional to the frequency, in other words,

Where
v = Velocity
f = Frequency
Speed is not given but if the distance traveled in a certain time, that is

Replacing



Substituting this value at our first equation we have



Therefore the wavelength of the seismic wave is 2000m
Answer:
reduce passive stiffness and increase range of movement during exercise.
Explanation:
stretching performed as part of a warm up prior to exercise is thought to reduce passive stiffness and increase range of movement during exercise. in general it appears that is static stretching is most beneficial for athletes requiring flexibility for their sports.
There is no SI "base unit" of density.
(Any unit of mass) divided by (any unit of volume) is
a valid unit of density.
The units of density that are seen most often are
(gram per cm³) and (kgm per meter³) .
Answer:

Explanation:
= Initial diameter = 4 cm
= Initial velocity = 1 m/s
= Final diameter = 7.8 m
= Final velocity
= Area = 
From the continuity equation we get

The speed of water at the second floor is
.
