Answer:
i think it A
Step-by-step explanation:
Velocity
Formula wise:
1/2 x mass x velocity^2
Answer:The equation relating I, r, and k is I =K/r²
Step-by-step explanation:
The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound can be written as
I ∝ 1/r²
Introducing the constant of proportionality, K we have that
I =K x 1/r²
Therefore , the equation relating I, r, and k is I =K/r²
Opposite angles
Opposite angles are non-adjacent angles that are formed by two intersecting lines. They are congruent.
