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 meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 65.5-gram mass is attached at the 21.0-cm
Gnesinka [82]

Answer:

113.53 g

Explanation:

Please see attached photo for explanation.

In the attached photo, M is the mass of the meter stick.

The value of M can be obtained as shown below:

Clockwise moment = M × 10.5

Anticlockwise moment = 65.5 × 18.2

Anticlockwise moment = Clockwise moment

65.5 × 18.2 = M × 10.5

1192.1 = M × 10.5

Divide both side by 10.5

M = 1192.1 / 10.5

M = 113.53 g

Thus, the mass of the meter stick is 113.53 g

Tanzania [10]

Answer:

60

Explanation:

Translation -

A book weighing 12 N is balanced on a table. Knowing that the static friction coefficient is 0.5, how much is the friction force worth?

Friction force is

f = u * n

f = 0.5 * 12N

f = 60
