Answer:
Crest: the top point of a wave
Trough: the lowest point of a wave
Wavelength: the distance from one crest to the next crest OR from one trough to the next trough
Amplitude: the distance the wave travels from the initial position (that would be that line in the middle) in either direction
<span>All of these are directly proportional to each other, meaning that if one goes up or down, they all do the same.
So if the temperature increases so does the heat. If the heat increases then so does the thermal energy. If the temperature goes up then so does the thermal energy. ETC...</span>
acceleration= change in velocity/ time taken
initial velocity=(36×1000m)/3600
= 10m/s
final velocity= (54×1000m)/3600
=15m/s
change in velocity= final - initial
=15 - 10
=5m/s
time taken = 5s
acceleration=15/5
=3metre per second square
Answer: Only 2 and 3
Explanation:
2.) Wavelength has an inverse relationship with wave frequency when wave speed remains constant.
3.) Wave speed is directly related to the product of wavelength and frequency.
V = F(λ)
Where
V = wave speed
F = wave frequency
(λ) = wavelength.
Answer:
the government's use and control of science. To clarify, I live in the U.S. I'm only interested in how the U.S. government dictates science. If you have any information or links that could educate me on this topic, I would be appreciative.
