Answer:
1. Our ears can sort out the individual sine waves from a mixture of two or more sine waves, so we hear the pure tones that make up a complex tone.
Explanation:
A complex tone is a sound wave that consist of two or more forms of audible sound frequencies. Sound wave is a mechanical wave that is longitudinal, and could be represented by a sine wave because of it sinusoidal manner of propagation.
A Fourier analyzer can be used to differentiate individual sine waves from a combination of two or more of it; which is as the same function performed by human ear. To the human ear, a sound wave that consist of more than one sine wave will have perceptible harmonics which would be distorted and turn to a noise.
Thus, the human ear makes it possible to hear the pure tones that make up a complex tone.
<span>procedure would most likely help determine a chemical property of the substance is : exposing it to a flame to see if it catches on fire
Chemical property is the characteristic that a substance has that differntiate it with another substance. The most common charatcteristics that most scientists wanted to know are :
- It's flamability
- It's radioactivity
- Its toxicity
By throwing the object into fire, we will easily find out these 3 characteristics</span>
Answer:

Explanation:
We are asked to find the distance a body covers. We know the initial velocity, acceleration, and time, so we will use the following kinematic equation.

The body starts at rest with an initial velocity of 0 meters per second. The acceleration is 8 meters per second squared. The time is 3.0 seconds.
= 0 m/s - a= 8 m/s²
- t= 3 s
Substitute the values into the formula.

Multiply the first set of parentheses.


Solve the exponent.

Multiply again.


The body will cover a distance of <u>36 meters</u>.
Fermentation is an aerobic process which means it uses oxygen. anaerobic is a process with out oxegyn
Answer:
1. 15.64 m/s
2. 2,354,400 seconds
Explanation:
1. 1mile is equivalent to 1609metres and 1hour is equivalent to 3600sec.
35mph = (35×1609)/3600
= 56315/3600
= 15.64 m/s
2. Note that 1 day ===> 24hrs
60min ==> 1hr
60sec ===> 1min
Thus 27.25 days = 27.25×24×60×60
= 2,354,400 seconds
