Answer:
1.76923077 meters
Explanation:
wavelength is denoted by the letter lambda it is equal to the speed (v) of a wave in a medium (air , water, light) divided by frequency , equals wavelength . so wavelength = v/f or = 23m/s ÷13hz
(1 Point)
4 m/s2
2.5 m/s2
1.5 m/s2
1 m/s2
Answer:
1.5
Explanation:
resultant force=8-5=3N
using f=ma
a=f/m
=3/2
=1.5
B. Neither ultrasonic nor infrasonic vibrations can be heard by humans.
C. Infrasonic vibrations are used in sonar equipment as well as to detect flaws in steel castings.
D. Ultrasonic vibrations have a frequency lower than the range for normal hearing.
the answer is B, Good luck!
B) They are absorbed
C) The change into P-waves
D) They change into L-waves
Answer:
B) They are absorbed
Explanation:
B is correct because S waves can only travel through solid materials. When they hit liquid materials they are absorbed in and undetectable.
Answer:
B) They are absorbed
Explanation:
When they hit the liquid core, S-waves are no longer able to be detected. While P-waves bounce off the liquid core, S-waves are absorbed at the core.
Potential energy, unlike kinetic, is stored energy. This energy comes from different sources. An object with potential energy also has the ability to produce energy if something triggers it. Example, a charged battery, a car on top of a hill, and capacitors.
