Answer:

Explanation:

There are many different testable hypothesis and experiments that can be made in order to prove this. Since there are no available statements let me provide one.

Testing and Comparing the excrement of wild and tamed horses.

This is because the excrement of tame horses will show higher levels of man-made chemicals and additives due to the different man-made horse food that the owners are giving them. Wild horses on the other hand will not since they nourish themselves on naturally grown grass.

6. What is the wavelength (in meters) of the electromagnetic carrier wave transmitted by The Sports

Vsevolod [243]

Answer:

wavelength = 2.81 m

Explanation:

Given that,

The frequency of the Sports Fan radio station, f = 106.4 MHz

We need to find the wavelength (in meters) of the electromagnetic carrier wave. The relation between frequency and wavelength is given by :

$c=f\lambda$

Where,

$\lambda$ is wavelength

$\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{106.4\times 10^6}\\\\\lambda=2.81\ m$

So, the wavelength of the electromagnetic carrier wave is 2.81 m.

Answer:

<h3>The answer is 8.29 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\% \\$

From the question

actual density = 19.30g/L

error = 20.9 - 19.3 = 1.6

We have

$p(\%) = \frac{1.6}{19.3} \times 100 \\ = 8.290155440...$

We have the final answer as

<h3>8.29 %</h3>

Hope this helps you
