The place theory of hearing is better than frequency theory at explaining pitch perception for __________ sounds

Physics
2 answers:
Licemer1 [7]3 years ago
6 0

Answer choices are:

A. low frequency

B. low and high frequency

C. mid-range

D. high frequency

____________________________________________________________

Correct answer choice is:

A. Low frequency .

____________________________________________________________

Explanation:

Place theory is a theory of hearing which declares that our judgment of sound depends on where each element frequency generates oscillations along the basilar layer. According to the frequency theory, the pulse rate of the nerve vibrations of the hearing nerve communicates to the rate of a pitch, which enables us to identify its pitch. The complete basilar layer is stimulated by sound waves at various frequencies.

The answer is : Low frequency sounds

place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along basilar membrane, which is very sensitive to low frequency sound

To move a heavy object, like a refrigerator what could be used to help decrease the frictional force?
Olenka [21]

Answer:

A. Remove everything in the refrigerator to lighten the load.

B. Put a lubricant between the surface of the object and the floor

C. Use round objects, like pencils , to decrease the friction and push the refrigerator over the pencils more easily

Explanation:

Force of friction is a resistance force which acts between two surfaces which are in relative motion. Friction is both boon and bane. Due to friction, we are able to sit, walk etc but also, due to friction there is dissipation of energy. Friction can be reduced by applying lubricants, reducing contact area, reducing the load.

F = μN where N is the normal force which depends on the mass.

Thus, by reducing the load, force of friction can be reduced. Round objects like wheels can also be used. By this the contact area reduces.

The third one pls help
Nadya [2.5K]

Answer:

20 ms¯¹

Explanation:

3. Determination of the final velocity

From the question given above, the following data were obtained:

Time (t) = 4 s

Acceleration (a) = 5 ms¯²

Initial velocity (u) = 0 ms¯¹

Final velocity (v) =?

Acceleration is simply defined as the change in velocity per unit time.

Mathematically, it can be expressed as:

Acceleration (a) = final velocity – Initial velocity / time

a = v – u / t

With the above formula, we can obtain the final velocity of the car as follow:

Time (t) = 4 s

Acceleration (a) = 5 ms¯²

Initial velocity (u) = 0 ms¯¹

Final velocity (v) =?

a = v – u / t

5 = v – 0 / 4

5 = v / 4

Cross multiply

v = 5 × 4

v = 20 ms¯¹

Thus, the final velocity of the car is 20 ms¯¹
