The layers of a jawbreaker is all made of the same material. The layers of the Earth are not, it is made of different kinds of rock, magma, and metal is inside of the core
Answer:
2.84 seconds
Explanation:
t = ?
distance = 125
Velocity origianal = 60 m/hr = 88 ft/s
AVERAGE velocity = 88/2 = 44 ft/s
44 t = 125
t = 125/44 = 2.84 s
The wave travels at the speed of sound in water:
.
The frequency of the wave is
so we can find its wavelength
by using the basic relationship between frequency, wavelength and speed of the wave:
Based on the scenario,
The thing that the result say about distance covered is :
it tells you that the distance covered is equal to the average speed times the travel time
hope this helps
