One theory of pitch perception is the ________ theory, which suggests that the rate at which neurons in the ear fire produce different pitches. This theory is particularly effective at explaining humans' perception of lower pitches. a. place
b. frequency
c. volley
d. opponent-process

Answers

Answer:

b. frequency

Explanation:

The frequency theory states that the human ear allows you to hear the different frequencies that are generated by the waves of sound, this is why we can hear different sounds and pitches, humans across the story have had the ability to hear lower pitches because that is the main pitch in which we humans speak, so te human ear adapted to hear better and pay closer attention to those pitches, so the frequency theory explains why humans can hear lower pitches.

Explanation:

An airplane traveling 1000 m above the ocean at 140 km/h is going to drop a box of supplies to shipwrecked victims below.(b) What is the horizontal distance between the plane and the victims when the box is dropped?

Answers

Answer:

Horizontal distance = 555.74 m

Explanation:

Given the following data;

Height = 1000m

Horizontal velocity = 140km/h

First of all, we would convert the unit of the velocity to meters per seconds;

V = (140 * 1000)/60*60

V = 140000/3600 = 38.89m/s

To find the time, we would use the second equation of motion;

$S = ut + \frac {1}{2}at^(2)$

We know that acceleration due to gravity, g is equal to 9.8m/s²

Initial velocity, u = 0

Substituting into the equation, we have;

$1000 = 0(t) + \frac {1}{2}*9.8*t^(2)$

$1000 = 0 + 4.9*t^(2)$

$1000 = 4.9*t^(2)$

$t^(2) = \frac {1000}{4.9}$

$t = √(204.08)$

Time, t = 14.29 secs

To find the horizontal distance;

Speed = distance/time

$Horizontal \; distance = horizontal \; velocity * time$

$Horizontal \; distance = 38.89 * 14.29$

Horizontal distance = 555.74 m

If you are trying to lose weight and otherwise improve your health, you may already be mindful about what you eat during the day. You might skip breakfast. At lunch, you may opt for a salad with lots of veggies, no croutons and low-fat dressing -- on the side, of course. Then, three o'clock hits.
