What happens to the pitch you hear when two sound waves constructively
interfere?
A. It increases due to the Doppler effect.
B. It decreases due to the Doppler effect.
C. The pitch does not change.
D. You hear the pitch of the louder sound.

Answers

Answer: D

Sound waves with higher amplitudes sound louder than sound waves with lower amplitudes. Constructive interference will make a sound louder while destructive interference will make a sound quieter. Two waves that add together may have different frequencies.

The answers to this would be D

The amount of a radioactive substance remaining as it decays over time is A = A0(0.5)t/h ,where a represents the final amount
Ao represents the original amount, t represents the number of years, and h represents the half-life of the sibstance.
The half-life of the radioactive isotope carbon-14 is 5,730 years. Approximately how many years will it take a 50-gram mass of
carbon-14 to decay to 5 grams?

Answers

Carbon-14 will take 19,035 years to decay to 10 per cent.

What is the time of decay?

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.

An exponential decay can be described by the following formula:

[tex]N(t)=N_oe^{-\lambda t}[/tex]

Where:

No = The quantity of the substance that will decay.

N(t) = The quantity that still remains and has not yet decayed after a time t

[tex]\lambda[/tex] = The decay constant.

One important parameter related to radioactive decay is the half-life:

[tex]t_{1/2}=\dfrac{Ln(2)}{\lambda}[/tex]

If we know the value of the half-life, we can calculate the decay constant:

[tex]\lambda =\dfrac{ln(2)}{t_{1/2}}[/tex]

Carbon-14 has a half-life of 5,730 years, thus:

[tex]\lambda =\dfrac{ln(2)}{5730}[/tex]

[tex]\lambda[/tex] = 0.00012097

The equation of the remaining quantity of Carbon-14 is:

[tex]N(t)=N_oe^{-0.00012097t}[/tex]

We need to calculate the time required for the original amount to reach 10%, thus N(t)=0.10No

[tex]0.10N_o=-N_oe^{-0.00012097t}[/tex]

Simplifying:

[tex]0.10=e^{0.00012097t}[/tex]

Taking logarithms:

ln(0.10) = -0.00012097t

Solving for t:

[tex]t=\dfrac{Log0.10}{-0.00012097}[/tex]

t = 19035 years

Carbon-14 will take 19,035 years to decay to 10 per cent.

Answer:

angle 1 and 4 are vertical angles

angle 1 plus angle 2 = angle 4

angle 2 and angle 7 are all of the above

Step-by-step explanation:

1. complementary angles are angles that have a sum of 90. because the angles are vertical angles they are congruent so the angles are likely not going to equal 45 degrees

vertical angles are angles that are vertically aligned with each other

adjacent angles are angles that share a common vertex, because these angles are not right next to each other they do not share a common vertex hence they are not adjacent angles

2. The answer choice shows the proof that an exterior angle is equal to the sum of its opposite interior angles

angle 4 being the opposite angle and angles 1 and 2 being opposite interior angles

3 The image shown is an example of corresponding angles

From looking at the image and then looking at the question we can tell that angles 2 and 7 are corresponding angles

Corresponding angles are congruent

Angles 2 and 7 are also obtuse angles. We know this because the angle formed is larger than a right angle

Answer:

1 &4 are vertically opposite angle

angle 1+angle 2=angle 4 exterior angle of the triangle is equal to the sum of two opposite interior angle

angle 2 and angle 7 are corresponding angle

Find the value of y.

Answers

Answer:

y = 6

Step-by-step explanation:

This is a special right triangle with angle measures 90° 60° 30°

the side length that sees angle measure 30 is represented with x

the side length that sees angle measure 90 is represented with 2x

and the side length that sees angle measure 60 is represented with x√3

the side length that sees angle measure 90 is given as 4√3 which means 2x = 4√3 divide both sides by 2

x = 2√3 now to find y, we need to multiply this value by √3

2√3 × √3 = 2 × 3

Answer:

130.25 ft.

Step-by-step explanation:

The semi circle has a length 1/2 of the circumference of the circle with a diameter of 25

C = πd = 3.14(25)

So, the semi circle has a length = 1/2(3.14)25) = 39.25

The distance for the rectangle = 33 + 25 + 33 = 91

Therefore, the total perimeter = 91 + 39.25 = 130.25
