Is it a must that a nucleus must have opposite nature with the electron

Generally, the nucleus of an atom has a positive CHARGE because of the protons (not sure what you mean by nature) which helps attract the electrons the nucleus but it stays within it's electron cloud. 

It cannot have the same charges as electrons (being negative) as the electrons would be repelled and the atom would lose it's structure.

I hope this answers the question.

When the hydraulic conductivity Ks = 10 mm/hr; effective matrix potential Ns = 20 mm, and rainfall intensity I = 30 mm/hr , dete
Maslowich

Answer:

t =  0.75 \ hr  =  0.75 *60  =  45 \ minutes

Explanation:

From the question we are told that

   The  hydraulic conductivity is  Ks =  10\ mm/hr

    The  effective matrix potential Ns  =  20 \ mm

    The  intensity of  rainfall is  I  =  30 \ mm/hr

    The runoff rate R =  15 \  mm/hr

Generally the run off rate is mathematically represented as  

      R = (I - Ks) t

Here t is the amount of runoff generated

=>   15 = (30 - 10) t

=>  t  =  0.75 \ hr

converting to minutes

    t =  0.75 \ hr  =  0.75 *60  =  45 \ minutes

A simple pendulum consists of a small object of mass 1.70 kg hanging at the end of a 2.50 m long light string that is connected
kompoz [17]

Answer:  3.63 Nm

Explanation:

from the question we were given the following

mass = 1.7 kg

length of the string (r) = 2.5 ,m

angle θ = 5 degrees

acceleration due to gravity (g) = 9.8 m/s

we can calculate the torque using the formula Torques = m x g x r x sin θ

torque = 1.7 x 9.8 x 2.5 x sin 5

torque = 3.63 Nm
