Answer:
=
Explanation:
Given:
For the first solenoid
Number of turns, n₁ = 1200 turns/m
Current, I₁ = 2.5 A
Paramagnetic material temperature, T₁ = 320 K
Now for the second solenoid
Number of turns, n₂ = 1000 turns/m
Current, I₂ = 0.85 A
Paramagnetic material temperature = T₂
The magnetic flux (B) is given as
where,
c = curie's constant
μ₀ = arithmetic constant
also it is given that the magnetization in both the cases are same
therefore the magnetic flux will also be equal
thus,
=

The stake, height and tether length of the tent form a right angle triangle where the tether length is the hypotenuse.
Applying Pythagoras theorem:
length² = height² + (stake distance)²
length = √(8² + 2²)
length = 8.5 feet
<u>Answer:</u> The correct answer is Option 3.
<u>Explanation:</u>
Amplitude of as sound wave is defined as the extent to which the air particles are getting displaced.
Speed of the sound wave is defined as the distance traveled by the sound wave per unit time and is not related to the amplitude of a sound wave.
Wavelength of the sound wave is defined as the difference between two crests or troughs.
Loudness of a sound wave is defined as the size of the vibration which are produced by it. This is closely related to the amplitude of the sound wave.
Pitch is defined as the sensation of the frequency. Higher the frequency, the pitch is also high and vice-versa.
From the above information, the amplitude of a sound wave is most closely related to the sound’s loudness.
Hence, the correct answer is Option 3.
Answer:
different temperatures
Explanation:
The independent variable would be <u>different temperatures</u>.
<u>The independent variable is the variable that is manipulated or varied in an experiment in order to see the effects it will produce on another variable</u> - the dependent variable. The values of the independent variable are directly inputted by the researcher and are not changed by any other variable throughout the experiment.
In the illustration, the effect of a variation in temperature is determined by counting the number of yeast cells. This showed that the manipulated variable is the temperature and hence, the independent variable.

Abiotic components are the non-living components in an ecosystem, like water, minerals, sunlight and air.
Biotic components are the living components that make up an ecosystem, like plants and animals. So bacteria is not an example of an abiotic component.
