Answer:
The answer to this is
6600 Hz to 19,800 Hz
Explanation:
The shape of the human ear is analogous to a closed ended pipe hence
we have λ = 4L or wavelength = 4 * length of the child ear
The frequency c/λ where c = speed of sound = 343 m/s
hence the child's audible range is multiples of 343/(4*0.13) =6600Hz
or 13200 Hz or 19,800 Hz
The generally quoted range of human hearing is 20 Hz to 20 kHz
Answer:
Taking a child away from their parents is awful, so taking your hand away from your body is awful.
I'm not sure if there were word choices for this particular question, but I do hope this helps!
Explanation:
Spaceship A moves at 0.800 in the positive – direction, while spaceship B moves in the opposite direction at 0.750 (both speeds are measured relative to Earth). What is the velocity {A,B} of spaceship A relative to spaceship B
Fertility is the biological capacity to bear children.
None of the other answers come close to being true. When we're talking about fertility, we're always talking about the ability of a person; woman to bear children.
