Answer:
the formula for calculating acceleration is ending speed minus starting speed divided by time.
Moving clouds. The doppler effect is specifically used to measure motion.
Answer:
the fundamental frequency produced by the open pipe is 120.78 Hz
Explanation:
Given;
length of the open pipe, L = 1.42 m
speed of sound in air, v = 343 m/s
The length of the open pipe for the fundamental frequency is equivalent to half of wavelength;

The fundamental frequency produced by the open pipe is calculated as;

Therefore, the fundamental frequency produced by the open pipe is 120.78 Hz
The answer is Alternating Current
Explanation:
The static pressure is P = ρgh, where ρ is the density of the fluid and h is the depth.
For the first person:
P = (1000 kg/m³) (9.8 m/s²) (2.3 m)
P = 22,500 Pa
For the second person:
P = (1000 kg/m³) (9.8 m/s²) (3 m)
P = 29,400 Pa
