Answer:
Magnitude of the induced emf is 11.62 V
Explanation:
Given:
No. of turns of the circular coil, N=185
Radius, R=4.50 cm=0.045 m
No. of turns of solenoid per meter(m), n=350
a=12.5 A
b=2.10
Now,
To determine the emf induced in the coil at t = 1.50 s:
The given equation is:
Now,
Now, substituting the respective values:
Now,
where,
A=Area=
Thus,
The correct option is A.
Elements are substances that are made up of atoms of the same type., while compounds are made of two or more atoms of different types.
Some common examples of elements are Iron, Sodium, oxygen, Hydrogen, while NaCl ( Sodium Chloride), Water (H_2O) , Ammonia (NH_3) are compounds.
It can be seen that the compounds are composed of atoms of different substances.
Chlorine is a diatomic molecule, where two Chlorine atoms are bonded by a covalent bond. Since both atoms in a Chlorine molecule are the same, it cannot be called a compound.
Hence Chlorine, though it has more than one atom in its molecular form, is still called element.
Answer:
Frequency of sound wave = 198.83 hertz (Approx.)
Explanation:
Given:
Velocity of sound wave in air = 340 m/s
Wavelength = 1.71 meter
Find:
Frequency of sound wave
Computation:
Frequency = Velocity / Wavelength
Frequency of sound wave = Velocity of sound wave in air / Wavelength
Frequency of sound wave = 340 / 1.71
Frequency of sound wave = 198.8304
Frequency of sound wave = 198.83 hertz (Approx.)
Wave speed = frequency * wavelength
We need to rearrange this equation because we are finding the wavelength :
Wavelength = wave speed / frequency
To rearrange it, I just divided it by frequency so that wavelength was the subject.
Now, input these numbers into this equation :
Wavelength = wave speed / frequency
Wavelength = 25 / 5
Wavelength = 5m
