Answer:
(A) A pitch that is higher than the pitch actually produced
Explanation:
Doppler effect
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 .

A. What can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>
<h3>
What is the principle of conservation of energy?</h3>
The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
The energy of a system can be converted from one form to another.
Thus, what can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>

Answer:
False
Explanation:
The force of an object does not depend on the dimensions of the said object. The formula for force is
F = Ma, where
m = mass and a = acceleration
The force is dependent on the size of the object and its acceleration. An object 2m by 5m running at a acceleration of x m/s² and weighing y kg will have the same force as another object 15m by 25m running at the same acceleration x m/s² and weighing y kg
Answer:
true
Explanation:
it all depends on the elements that are burning for the different types of colors.
