Answer:
1.5 m/s.
Explanation:
The Speed of a wave is the product of the wavelength and its frequency or it is the ratio of it wavelength and its Period. It can be expressed mathematically as
V = λf or λ/T .............................. Equation 1
Where V = speed of the wave travelling on the string, λ = wavelength of the wave, T = period of the wave, F = frequency of the wave.
Given: λ = 1.8 m ( distance it takes to repeat itself), T = 1.2 s (Time taken to complete a full cycle)
Substitute into equation 1
V = 1.8/1.2
V = 1.5 m/s.
Hence the wave is 1.5 m/s fast.
The torque value is 560 Nm, so the result does not depend on the value of Ф.
Given:
Mass=80.0 g
Radius=20.0 cm
Magnetic field=0.35T
In a magnetic field, a loop of current-carrying wire will experience the following torque:
τ=μ×Β
Here, is the μ magnetic moment and Β is the magnetic field.
τ= 1600 × 0.35 T
τ= 560 Nm
<h3>
What is torque and its SI unit?</h3>
The rotating equivalent of force is torque. It is also known as the moment, moment of force, rotating force, or turning effect depending on the field of research. It serves as an example of how a force can alter a body's rotational motion.
The Newton-metre, or kgm2sec-2, is the SI unit for torque. How did we get to this point? Considering the equation Torque = Force X Distance Torque is measured in newton-meters, whereas distance is measured in meters and force is measured in newtons.

The nitrogen fixation is the process of conversion of nitrogen gas into a usable form.
Answer: Option 3
<u>Explanation:
</u>
The nitrogen fixation is the process where the nitrogen gas present in air gets trapped and converted into ammonia or other nitrogenous compounds. This is the first step of nitrogen cycle.
The atmospheric nitrogen will get absorb in soil and gets converted to either ammonia which acts as nutrition for plants or other nitrogen related compounds which acts as fertilizers.
So, the nitrogen which get converted to usable stable form of nitrogen compounds can be used by plants, microorganisms and other organisms in the ecosystem.
