All look good, but i’m pretty sure 7 should be velocity
Through the 1/r law, it was concluded that for the sound intensity or pressure is directly proportional to distance or radius. That is,
p = k/r
where k is the proportionality constant. If the distance of a sound wave is quadrupled then, the intensity of the sound is decreased to 1/4 of its original value.
Answer:
= F Δt / m
Explanation:
The impulse theorem and momentum is
I = Δp
F Δt = m
- m v₀
Before touching the ball is without movement, the force is represented by the kinetic energy of the club when it reaches the bottom of the path, so if this force is constant, the time [or the duration of the blow is directly proportional to the speed that the ball acquires.
= F Δt / m
The higher this speed, the greater the distance traveled.
