They are similar because of their colour theyre differnt because there aint any silver
Answer:
176ft/s
Explanation:
Speed of a wave is a function of the frequency and wavelength of the wave. It is expressed mathematically as:
V = fλ where:
V is the speed of the wave
f is the frequency
λ is the wavelength
Given f = 16Hz, λ = 11ft
V = 16×11
V = 176ft/s
Answer:
As follows,
Explanation:
KE=1/2mv^2
In 1st question,
KE=1/2mv^2=1/2*0.05*12=0.3 J [50g=0.05 kg]
In 2nd question,
KE=1/2mv^2
6.8=1/2*0.046*v^2
v=sqrt(6.8/0.023)
v=17.19
In 3rd question,
KE=1/2mv^2
63/392=m
m=0.16kg=160g
For 4th,
a.
1st case,
KE=1/2mv^2=1/2*28*2.4^2=80.64
2nd case,
KE=1/2mv^2=1/2*28*3.7^2=191.66
Change in KE=191.66-80.64=11.02
b.Speed/velocity gained
Answer:
there's no picture
Explanation:
and what would the question be anyways?
T<span>he relationship between wavelength and frequency is inverse.
This is as the wavelength increases the frequency decreases and as the wavelength decreases the frequency increases.
The light meets this equation that reflects the relationship between wavelength and frequency:
c = wavelength * frequency => wavelength = c / frequency
where c is the constant speed of light.
