Answer:
32.5 m/s
Explanation:
Given:
Δy = 50 m
a = -10 m/s²
t = 2.5 s
Find: v₀
Δy = v₀ t + ½ at²
(50 m) = v₀ (2.5 s) + ½ (-10 m/s²) (2.5 s)²
v₀ = 32.5 m/s
b.it's commercially reprocessed
c.some is reprocessed for national defense
d.some of it is sold to the public
the answer is b. it's commercially reprocessed
Answer: centimeters per second (cm/s)
Explanation:
The relation between the frequency and the wavelenght is:
Velocity = wavelenght*frequency.
So in a relation of wavelenght vs frequency, we will have the relationship:
Where wavelenght is Y and frequency is X
wavelenght = velocity/frequency.
So the constant is the velocity, and we know that the units of the wavelenght is cm, the unit of frequency is Hz (or 1/s), so the units of the velocity is cm/s
Answer:
cm/s
Explanation:
λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.
λ = c/v which is in cm/s/Hz
But we would use just cm! Because that's how we measure the wavelength in this example.
However, the constant is c, the speed of light, which we measure as a speed, so cm/s will do.
B. Type
time. is the answer.
