Answer:
44%
Explanation:
The average power of a wave is directly proportional to the square of the frequency.
P ∝ ω²
Writing a proportion:
P₁ / P₀ = ω₁² / ω₀²
P₁ / P₀ = (1.2 ω₀)² / ω₀²
P₁ / P₀ = 1.44
P₁ = 1.44 P₀
The power increases by 44%.
I think it is a chemical reaction but im not completely sure
A theory cannot become a law because it explains what is observes and does not describe it.
Answer:
The value of g = 0.6168 m/s².
Explanation:
Given that,
On a planet X,
Length of the pendulum(L) = 0.25 meters,
Time period of the pendulum(T) = 4 seconds.
We have to find the 'g' value on the planet.
The 'g' value on a planet can be found by a pendulum with help of the formula,
T = 2π ×
From this, g = 4π² × ![\frac{L}{T^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BL%7D%7BT%5E%7B2%7D%20%7D)
Using the above formula and substituting the values,we get,
g = 0.6168 m/s².
Solution:
Formula for finding wavelength from frequency is wavelength=wave velocity(c)/frequency(f).
General value of Wave velocity (c) = 3 x 10^8 m/s
Given frequency = 2.0 x 10^6 Hz
Now,
Wavelength = 3 x 10^8 m/s / 2.0 x 10^6 Hz
= 150 m
Therefore the value of wavelength is 150m.
