Answer:

Volley theory

Explanation:

Frequency theory states that humans perceive sound based on patterns of time to which the neurons respond to sound in the cochlea. So the properties of sound like pitch of a pure tone is perceived by the neuron firing pattern. Frequency theory proposed that only one neuron was firing at a rate that mimics the frequency of the sound. This is not true, so a theory in which proposed that groups of neurons were responsible was born called Volley theory.

The appropriate response would be the Volley theory. This expresses gatherings of neurons of the auditory system, to react to a sound by firing action possibilities somewhat out of stage with each other so when consolidated, a more prominent frequency of sound can be encoded and sent to the brain to be analyzed.

A police car on the side of the road (at rest) uses a radar gun to catch speeders as they approach it. The frequency the radar g

oee [108]

Answer:

$\Delta f = 1.49 \times 10^9 Hz$

Explanation:

Apparent frequency that is received to the speeder is given as

$f_1 = f_0\frac{v + v_o}{v}$

$f_1 = (8 \times 10^9)\frac{340 + v_o}{340}$

here we know that

$v_o = 65 mph = 29 m/s$

now we have

$f_1 = (8 \times 10^9)\frac{340 + 29}{340}$

$f_1 = 8.68 \times 10^9 Hz$

now the frequency that is received back from the speeder is given as

$f_2 = f_1\frac{v}{v- v_o}$

$f_2 = (8.68 \times 10^9}\frac{340}{340 - 29}$

$f_2 = 9.49 \times 10^9 Hz$

So difference is the frequency is given as

$\Delta f = 9.49 \times 10^9 - 8 \times 10^9$

$\Delta f = 1.49 \times 10^9 Hz$

The carnival ride has a 2.0m radius and rotates 1.1 times persecond.

Lady_Fox [76]

Answer:

a) v = 13.8 m / s , b) a = 95.49 m / s² , c) a force that goes to the center of the carnival ride and d) μ = 0.10

Explanation:

For this exercise we will use the angular kinematics relationships and the equation that relate this to the linear kinematics

a) reduce the magnitudes to the SI system

w = 1.1 rev / s (2pi rad / 1rev) = 6.91 rad / s

The equation that relates linear and angular velocity is

v = w r

v = 6.91 2

v = 13.8 m / s

b) centripetal acceleration is given by

a = v² / r = w² r

a = 6.91² 2

a = 95.49 m / s²

c) this acceleration is produced by a force that goes to the center of the carnival ride

d) Here we use Newton's second law

fr -W = 0

fr = W

μ N = mg

Radial shaft

N = m a

N = m w² r

μ m w² r = m g

μ = g / w² r

μ = 9.8 / 6.91² 2

μ = 0.10
