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 .

Answer:
a)
85.05 N/m
b)
179.81 rad/s
Explanation:
a)
k = spring constant of the spring
m = mass of the block = 0.473 kg
x = stretch caused in the spring = 0.109 m
h = height dropped by the block = 0.109 m
Using conservation of energy
Spring potential energy gained by the spring = Potential energy lost by the block
(0.5) k x² = mgh
(0.5) k x² = mgx
(0.5) k x = mg
(0.5) k (0.109) = (0.473) (9.8)
k = 85.05 N/m
b)
angular frequency is given as
= 179.81 rad/s
Because of a difference in temperature.
The answer is periosteum. Hope this helps!
