The amplitude of a sound<span> wave </span>determines<span> its </span>loudness<span> or volume. A larger amplitude means a louder </span>sound<span>, and a smaller amplitude means a softer </span><span>sound</span>
Required Heat = Q
Q = Mass * specific heat of water * change in temp.
Q = 5g * 1g/cal*degC * 20degC
Q = 100 cal of heat is required
To convert calories to Joules,
1 cal = 4.184 Joules
100cal = 418.4 J of heat is needed
Hi ChloeRenee12345,
Your Question:
If the worlds human population stay away from all the fast foods that they purchase and consume their overall physical and mental state would be greatly affected
Answer:
Well absolutely not! Everyone will not be affected by not purchasing fast food, It will actually be better for the society. Fast food has bad properties that makes people get fat.
It’s true. longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!
Answer
The wavelength for 550 kHz signal is
λ = 545.45 m
The wavelength for 1600 kHz signal is
λ = 187.5 m
The wavelength for 88 MHz signal is
λ = 3.41 m
The wavelength for 108 MHz signal is
λ = 2.78 m
