The Bohr radius a0 is the most probable distance between the proton and the electron in the Hydrogen atom, when the Hydrogen ato
katen-ka-za [31]

Answer:

The electric force is  F =  11.9 *10^{-9} \ N

Explanation:

From the question we are told that

    The  Bohr radius at ground state is  a_o  =  0.529 A =  0.529 ^10^{-10} \ m

    The values of the distance between the proton and an electron  z =  2.63a_o

The electric force is mathematically represented as

     F  =  \frac{k * n  * p }{r^2}

Where n and p are charges on a single electron and on a single proton which is mathematically represented as

      n = p  =   1.60 * 10^{-19} \ C

    and  k is the coulomb's  constant with a value

           k =9*10^{9} \ kg\cdot m^3\cdot s^{-4}\cdot A^2.

substituting values

       F =  \frac{9*10^{9} *  [(1.60*10^{-19} ]^2)}{(2.63 * 0.529 * 10^{-10})^2}

         F =  11.9 *10^{-9} \ N

A submarine periscope uses two totally reflecting 45-45-90 prisms with total internal reflection on the sides adjacent to the 45
Likurg_2 [28]

Answer

Given,

Periscope uses 45-45-90 prisms with total internal reflection adjacent to 45°.

refractive index of water, n_a = 1.33

refractive index of glass, n_g = 1.52

When the light enters the water, water will act as a lens and when we see the object from the periscope the object shown is farther than the usual distance.

While seeds are forming, another plant part forms around them. Animals eat this part and carry the seeds to a new spot.
Eddi Din [679]

Answer:

<em>The correct option is D) fruit</em>

Explanation:

Both the gymnosperm and the angiosperms plants produce seed. Seeds are an essential part of reproduction in plants.

After fertilization has occurred, the ripened ovule is the part which turns into a seed. The size of the seeds depends on the type if plant.

After fertilization, the ovary forms the fruit. As the ovule is present in the ovule hence after fertilization, the seed which was made from the ovule gets enclosed in the fruit which was made from the ovary.
