P₁V₁ / T₁ = P₂V₂ / T₂
1.6 × 168 /255 = 1.3 × V₂ / 285
V₂ = 1.6 × 168 × 285 / (1.3 × 255)
V₂ = 231.095
The final volume = 231 cm³
Answer:
C. 216.0 cm³
Explanation:
Volume = mass ÷ density
Volume = 583.3 g ÷ 2.7 g/cm
Volume = 216 cm³
Any point in the wire has 1.12 x
. electrons flow per second.
<h3>What causes a current in a wire?</h3>
- Electric current in a wire, where electrons serve as the charge carriers, is a measurement of the amount of charge that moves through any point of the wire in a given amount of time.
- A free electron is drawn to a proton to become neutral if an electron is added to the wire.
- Lack of electrons can result from pushing electrons out of their orbits.
- Electric current is the name given to the constantly moving electrons in wire.
The current is the quantity of charge Q flowing through a certain point of the wire in a time interval of
.
I =
.
by using this relationship
I=1.80 A, we can find the charge passing any point in the wire in 1 second:
Electric Charge, Q = 1.80 C.
To find how many electrons corresponds to this charge, we should divide this value by the charge of a single electron
charge of the electron = 1.6 x
C.
No. of Electrons = Q/q =
= 1.12 x

The plum pudding model suggested that the electrons were dispersed throughout the atom (like chocolate chips in a cookie) and the space was positively charged so that in the end the atom was neutral. Today, people know that the electrons are in a "cloud" around the atom and the protons (and neutrons) are in the nucleus, at the center of the atom.
Answer:
30 minutes
Explanation:
Use half life equation:
A = A₀ (½)^(t / T)
where A is the final amount, A₀ is the initial amount, t is time, and T is the half life.
A = A₀ (½)^(t / T)
62.5 = 500 (½)^(t / 10)
0.125 = ½^(t / 10)
t / 10 = 3
t = 30
It will take 30 minutes.
