Answer:
f_tympanum = 256 Hz.
Explanation:
The eardrum is the vibrating membrane of the human ear, it works by resonance, that is, an external stimulus (force) makes it vibrate, as the eardrum is extremely light it can vibrate at the same frequency of the incident sound.
Consequently if the incident vibration is f = 256 hz, the eardrum resonates at the same frequency
f_tympanum = 256 Hz.
As a reference the response of the eardrum goes from f = 20 Hz f = 20000 Hz
Answer:
His average speed.
Explanation:
Average speed = Total distance travelled / total time .
In the given case odometer measures total distance travelled . Dividing it by time will give average speed .
Average velocity can not be the answer as it is measured by dividing displacement by time . Displacement here is zero because initial and final point are same . Instantaneous velocity is given by the speedometer . It keeps on changing all the time . It is actually speed at a particular point of time . It can not be average velocity or speed .
Answer: It’s c
explaining: i guessed
There are few equations that link acceleration and velocity.
One of them is derived from the definition of acceleration - is the rate of change of velocity in respect with time
a = v-u/t
at=v-u
a = acceleration
v=velocity at the end
u=velocity at the start
t=time
Now put everything you know and solve for time.
6t = 42 -0
6t = 42
t = 42 / 6
t = 7 second
It takes 7 seconds for the roccet to reach a velocity of 42 m/s
Hope it helps :).
Because the switch isn’t connected to the wire, so the electric charges that is going through the wire isn’t reaching both sockets for the lightbulb.
