Answer:
answer is (c) density is not a characteristics of vibration.
hope it is right answer for it!!
Answer:

Explanation:
We have,
Speed of an electron is 
It is required to find the De Broglie wavelength of electron. The formula for the De- Broglie wavelength is given by :

h is Planck's constant
m is mass of an electron
Plugging all the values we get :

So, the De-Broglie wavelength of an electron is 
Answer:
i. Magnetic fields
ii. All 4 planets in appearance have deeper atmospheres and darker cloud.
iii. All the 4 Jovian planets rotates very quickly, with a range of 10 to 17 hours.
Explanation:
The Jovian planets is different from terrestrial planets in so many ways. The Jovian planets includes Jupiter , Saturn, Uranus and Neptune.
The major similarities shared by all of these 4 planets includes
i. Magnetic fields: Each of this Jovian planets have a strong magnetic field and are generated by electric currents in its rapidly sniping interior. The magnetosphere which is the region at which the planet magnetic field dominates is far more stronger in Jupiter than other Jovian planets . Although the magnetic field of Saturn , Neptune and Uranus works in similar way to Jupiter but are less stronger.
ii. All 4 planets in appearance have deeper atmospheres and darker cloud. The uppermost clouds of Jupiter and Saturn has more of ammonia crystals .The upper cloud of Neptune is composed of methane, The cloud of Uranus is deep.
iii. All the 4 Jovian planets rotates very quickly, with a range of 10 to 17 hours. The rotation period of Jupiter is the shortest among the Jovian planets which is around 9 hours 55 minutes. The rotation period of Neptune and Uranus take longer time than the other 2 Jovian planets( a little above 17 hours).
The Results For Earth's Circumcised were quite accurate. the diameter of earth is 12,740 km, the length of the stadium would be 1,140 km.
Well the mean is when you add up the answers together and divide by how many there is so
1)the length is 10.2
2)the width is 3.25
