Answer:
6 and 14 respectively
Explanation:
proton number = atomic number
mass number = proton number + neutron number
since
- p.n = a.n = 6
- m.n = p.n + n.n
- m.n = 6 + 8 = 14
- m.n = 14
Answer:
decreases, but frequency increases.
Explanation:
Wavelength and frequency are inversely proportional, meaning the higher the frequency, the shorter the wavelength, and the lower the frequency, the longer the wavelength.
Answer:
C. It can be magnetized
Explanation:
As we know that Ferromagnetic materials are made up of small domains which can be treated as small magnets.
These small magnets are aligned in random directions so that the net magnetic field due to all small domains will cancel out and it gives no magnetic field by their own.
Now when these type of ferromagnetic substances are placed in external magnetic field then due to the external field these all domains are aligned in the direction of external magnetic field.
Due to this alignment of domains ferromagnetic substance produce their own field and this phenomenon is known as magnetization
So here correct answer will be
C. It can be magnetized
You have to draw a mathematical spatial axes .in order to judge is it right or not .. well you have to draw the crest and trough both of 1 cm in length and the total wavelength (same phase on the wave of 2 cm ) something like this
