Answer:
2) f = 0.707 Hz
Explanation:
Given m₁ = 1.0 kg , f₁ = 1.0 Hz
So using the equation
f₁ = ( 1 / 2 π ) * √K / m₁
Solve to determine K' constant of spring
K = m * ( 4 π ² * f ² )
K = 1.0 kg * ( 4 π ² 1.0² Hz )
K = 39.4784176
So given 2.0 kg the frequency can be find using formula
f₂ = ( 1 / 2 π ) * √K / m₂
f₂ = ( 1 / 2 π ) * √39.4784176 / 2.0 kg
f₂ = 0.707 Hz
Answer:
From liquid to solid or to solid or liquid the transition has to cross the grey zone.
Explanation:
hope it helps<
A. Refraction, meaning the same thing...it just passes through. Reflection is when light, heat, or sound bounces off a surface, kind of like an echo. Resonance is sound reverberating, or vibrating. And polarization is the action of not allowing the vibrations of a transverse wave. Hoped this helps you :)
Short answer: Refraction
X=15! hope this helps! Also please look at my questions about the cannon ball!!! need help!
The basic relationship between the frequency of a wave and its period is
where f is the frequency and T the period of vibration.
In our problem, the frequency is
so, by re-arranging the previous formula, we can find the period of the wave:
