First, we need to find the number of protons, which is the total mass divided by the mass of one proton:
N= \frac{m}{m_p}= \frac{1.0 kg}{1.67 \cdot 10^{-27} kg}=6.0 \cdot 10^{26} protons

Then, the total charge is the number of protons times the charge of a  single proton:
Q=Ne = 6.0 \cdot 10^{26}\cdot 1.60 \cdot 10^{-19} C=9.6 \cdot 10^7 C

9.6 x 10⁷ C.

<h3>Further explanation</h3>

<u>Given:</u>

  • The total mass of protons = 1.0 kg
  • The mass of one proton = 1.67 \times 10^{-27} \ kg
  • The elementary charge of proton = 1.602 \times 10^{-19} \ C

<u>Question:</u>

What is the charge on 1.0 kg of protons?

<u>The Process:</u>

Atoms consist of smaller or subatomic particles, namely protons (p), electrons (e), and neutrons (n).

  • Protons are positively charged subatomic particles.
  • Electrons are negatively charged subatomic particles.
  • Neutrons are subatomic particles with no charge.

<u>Step-1: find the number of protons</u>

\boxed{ \ N = \frac{total \ mass}{mass \ of \ one \ proton} \ }

\boxed{ \ N = \frac{1.0 \ kg}{1.67 \times 10^{-27} \ kg} \ }

Hence, \boxed{ \ N = 5.99 \times 10^{26} \ protons} \ }

<u>Step-2: find the charge</u>

By using this formula,

\boxed{ \ Q = Ne \ }

we calculate the total charge of the protons.

Recall e = 1.602 \times 10^{-19} \ C

\boxed{ \ Q = (5.99 \times 10^{26})(1.602 \times 10^{-19}) \ }

Thus, the charge on 1.0 kg of protons is \boxed{\boxed{ \ 9.6 \times 10^7 \ C \ }}

<u>Quick Steps</u>

\boxed{ \ Q = 1.0 \ kg \times \frac{1 \ proton}{1.67 \times 10^{-27} \ kg} \times \frac{1.60 \times 10^{-19} \ C}{1 \ proton} \ } \rightarrow \boxed{ \ Q = 9.6 \times 10^7 \ C \ }

A concave mirror has a focal length of 13.5 cm. This mirror forms an image located 37.5 cm in front of the mirror. Find the magn
77julia77 [94]

Explanation:

It is given that,

Focal length of the concave mirror, f = -13.5 cm

Image distance, v = -37.5 cm (in front of mirror)

Let u is the object distance. It can be calculated using the mirror's formula as :

\dfrac{1}{v}+\dfrac{1}{u}=\dfrac{1}{f}

\dfrac{1}{u}=\dfrac{1}{f}-\dfrac{1}{v}

\dfrac{1}{u}=\dfrac{1}{(-13.5)}-\dfrac{1}{(-37.5)}

u = -21.09 cm

The magnification of the mirror is given by :

m=\dfrac{-v}{u}

m=\dfrac{-(-37.5)}{(-21.09)}

m = -1.77

So, the magnification produced by the mirror is (-1.77). Hence, this is the required solution.

Answer:

serie Ceq=0.678 10⁻⁶ F  and the charge Q = 9.49 10⁻⁶ C

Explanation:

Let's calculate all capacity values

a) The equivalent capacitance of series capacitors

    1 / Ceq = 1 / C1 + 1 / C2 + 1 / C3 + 1 / C4 + 1 / C5

    1 / Ceq = 1 / 1.5 + 1 / 3.3 + 1 / 5.5 + 1 / 6.2 + 1 / 6.2

    1 / Ceq = 1 / 1.5 + 1 / 3.3 + 1 / 5.5 + 2 / 6.2

    1 / Ceq = 0.666 + 0.3030 +0.1818 +0.3225

    1 / Ceq = 1,147

    Ceq = 0.678 10⁻⁶ F

b) Let's calculate the total system load

   Dv = Q / Ceq

   Q = DV Ceq

   Q = 14 0.678 10⁻⁶

   Q = 9.49 10⁻⁶ C

In a series system the load is constant in all capacitors, therefore, the load in capacitor 5.5 is Q = 9.49 10⁻⁶ C

c) The potential difference

   ΔV = Q / C5

   ΔV = 9.49 10⁻⁶ / 5.5 10⁻⁶

   ΔV = 1,725 ​​V

d) The energy stores is

    U = ½ C V²

    U = ½ 0.678 10-6 14²

    U = 66.4 10⁻⁶ J

e) Parallel system

   Ceq = C1 + C2 + C3 + C4 + C5

   Ceq = (1.5 +3.3 +5.5 +6.2 +6.2) 10⁻⁶

   Ceq = 22.7 10⁻⁶ F

f) In the parallel system the voltage is maintained

   Q5 = C5 V

   Q5 = 5.5 10⁻⁶ 14

   Q5 = 77 10⁻⁶ C

g) The voltage is constant V5 = 14 V

h) Energy stores

   U = ½ C V²

   U = ½ 22.7 10-6 14²

   U = 2.2 10⁻³ J
