Answer:

The value is   q =  5.72 *10^7 \  C

Explanation:

From the question we are told that

  the mass is  m  =  1.53 \ kg

      The  atomic mass is  u  =  244 g/mol =  0.244 kg/mol

      The number of protons on each atom is N  =  94 \  protons

       The mass of one atomic mass unit is M  = 1.66 *10^{-27} \  kg

Generally the number of atoms present is  

       k  =  \frac{m *  N_a }{u}

Here  N_a is the Avogadro constant  with value N_a  =  6.023  *10^{23} \  atoms /mol

=>    k  =  \frac{1.53 * 6.023*10^{23}}{ 0.244}

=>   k  =  3.8 *10^{24} \  atoms

The coulombs of positive charge on the plutonium is mathematically represented as

     q =  k *  N  *  e

Here e is the charge on a proton with value e =  1.60 *10^{-19}\  C

    q = 3.8 *10^{24} *  94 *  1.60*10^{-19}

           q =  5.72 *10^7 \  C

What is the difference between free fall and weightlessness??
joja [24]
When you are in free fall, the force of gravity is stronger than your velocity perpendicular to where you're falling, and you move at a constant speed downwards.

Under feelings of weightlessness, you are still being pulled by gravity, but your perpendicular velocity and distance from the source can cancel each other out.

What type of material is good at transferring heat?
MatroZZZ [7]
The answer is A

Materials that are good conductors of thermal energy are called thermal conductors. Metals are very good thermal conductors. Materials that are poor conductors of thermal energy are called thermal insulators. Gases such as air and materials such as plastic and wood are thermal insulators

You connect five identical resistors in series to a battery whose EMF is 12.0 V and whose internal resistance is negligible. You
neonofarm [45]

Answer:

Explanation:

Total resistance in the circuit

= EMF / current in the circuit

= 12 / .969

= 12.383 ohm

This resistance consists of 5 identical resistances in series

resistance of each resistor

= 12.383 / 5

= 2.476 ohm .

potential difference on each

= current x resistance of each

= .969 x 2.476

= 2.399 V

= 2.4 V
