Sound is a longitudinal wave that carries energy. Sound needs a medium to propagate through (this means that sound cannot propagate in vacuum).
The medium usually determines the speed of the wave travelling through it.
As the sound waves travel in a medium, this medium begins to decrease, therefore, the energy of the sound also decreases.
Answer:9m
Explanation:
Ball starts from rest . Time taken = 6 seconds. Distance travelled by ball. ∴Distance travelled = 9 m
Hope it helps you
Good luck
Answer:
300 m
Explanation:
The ball moves with constant velocity, so the distance it covers is given by:
where
v=6 m/s is the ball's velocity
t=50 s is the time
Substituting these numbers into the equation, we find
Answer:
I think its tennis but im not sure
Explanation:
The current flowing through the circuit A is . I = e/r1 + r2.
<h3>What is circuit diagram?</h3>
An electrical circuit is depicted graphically in a circuit diagram. Simple pictures of the circuit's parts are used in pictorial circuit diagrams, where as standardised symbolic representations are used in schematic diagrams to depict the circuit's parts and connections.
"Your question is not complete, it seems to be missing the following information",
find the the current flowing through the resistors in circuit A;
The given parameters;
emf of each battery = e
internal resistance of circuit A = r₁
resistance of circuit = r₂
The equivalent resistance of the circuit A in series is calculated as follows;
Re = r1 + r2
emf = e
The current flowing through the circuit A is calculated as follows;
V = IR
I =V/R
I = e/r1 + r2
Thus, the current flowing through the circuit A is . I = e/r1 + r2
