How much force is needed to accelerate a 2500 kg car at a rate of 3.5 m/s^2?

Sati [7]

F = ma

F = applied force in newtons = to be determined

m = mass of the car = 2,500 kg

a = acceleration of the car = 3.5 m/s²

F = (2,500 kg)(3.5 m/s²)

F =8750

Sound enters the ear, travels through the auditory canal, and reaches the eardrum. The auditory canal is approximately a tube op

Juliette [100K]

Answer:

The fundamental frequency of can is 2.7 kHz.

Explanation:

Given that,

A typical length for the auditory canal in an adult is about 3.1 cm, l = 3.1 cm

The speed of sound is, v = 336 m/s

We need to find the fundamental frequency of the canal. For a tube open at only one end, the fundamental frequency is given by :

$f=\dfrac{v}{4l}\\\\f=\dfrac{336}{4\times 3.1\times 10^{-2}}\\\\f=2709.67\ Hz\\\\f=2.7\ kHz$
