Question

- For an electron to have the same de Broglie
wave length as that of a Deuteron, its velocity
should be times that of Deuteron
1) 1836
2) 1/1836 3) 3672 4) 1/3672

Answer 1

Answer:

Vaccines are made by taking viruses or bacteria and weakening them so that they can't reproduce (or replicate) themselves very well or so that they can't replicate at all. Children given vaccines are exposed to enough of the virus or bacteria to develop immunity, but not enough to make them sick.

Answer 2

Please mark as brainliest it was very hard

• Explanation -

de Broglie's wavelength of deuteron is

calculated by -

1 = h/(md.vd) ... (1)

For electron having same de Broglie's

wavelength

X = h/(me.ve) ...(2)

From (1) & (2),

h/(md.vd) = h/(me.ve)

me.ve = md.vd

ve/vd = md/me

ve/vd = 3.343x10^-27 / 9.1x10^-31

ve/vd = 3674

ve = 3674 vd

Therefore, velocity of electron should

be 3674 times that of deuteron to have

same de Broglie's wavelength.
