Get a new one and use the new one because the tape might break.
Answer:
Amplitude: 2cm
Period: 1/12 s
Wavelength: 10 cm
Speed: 120 cm/s
Explanation:
The amplitud is the vertical distance from the resting position to the crest or to the trough, and the vertical distance from a crest to a trough is two times the amplitude. Therefore the amplitud (A) is:
A= 4cm/2= 2cm
The period (T) is:
s
The wavelength is defined as the horizontal distance from a crest to the nearest crest or from a trough to the nearest trough. The distance from a crest to the nearest tough was given. Therefore two times that distance is the distance from a crest to the nearest crest.
The wavelenght (λ) is:
λ=(2)(5)=10cm
The speed (v) in a wave is given by:
v = λf
v=(10)(12)=120 cm/s
A
A charge moving through an electric circuit would gain electric potential energy in the internal circuit and lose electric potential energy in the external circuit. Charge has the greatest amount of electric potential energy at the - terminal of the battery.
Answer:
D, I think.
Explanation:
I had a quiz in Plate Tectonics and there was 2 questions that are related to this, but not the exact question.
Which material rises from cracks in oceanic crust
-molten rock
Which is the first step in the seafloor spreading process?
-a crack forms in oceanic crust.
those are all right btw, so you can decide if the answer I told you is right or not.
