Answer:
b)
Explanation:
The 3 frequencies found in the sound waveform (400, 1600, and 2400 Hz are related between them, being 400 Hz the fundamental frequency of the sound, and 1600 Hz and 2400 Hz, harmonics (overtones of the fundamental) according to this relationship:
1600 Hz = 4* 400 Hz (4th Harmonic)
2400 Hz = 6* 400 Hz (6th Harmonic)
Answer:
To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity.
0.17m/s²
Explanation:
According to newtons second law "the force on a body is depends on its mass and acceleration"
Force = mass x acceleration.
The more the mass and acceleration, the more the force a body possess.
Given that the acceleration of the body is 0.33m/s²
Force = 0.33 x mass
If the force on the body is halved, the acceleration will also be halved;
i.e:
Force = F
= 0.33 x mass
F =
x 0.33 x mass
F = 0.17 x mass
Force = acceleration x mass
Acceleration is 0.17m/s²
