Answer:
Direction
Explanation:
There are two types of electric current:
- DC (Direct current): in a direct current, the direction of the flow of the current is constant; this means that it does not change. This means that the potential difference supplied has always the same direction, so that the electrons travel always in the same direction through the circuit
- AC (Alternating current): in an alternating current, the direction of the flow of the current is constantly reverses. This means that the direction of the potential difference supplied constantly changes, therefore the electrons travel half the time in one direction and half the time in the opposite direction.
Answer:
When the electrical current passes through the conductors, the polarity is changed, and the diaphragm interacts with the permanent magnets, vibrating and creating sound.

Answer:
I only know that acid rain is one of them!! It can erode rocks and weather down
Explanation:
the amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. In Figure 10.2 sound C is louder than sound B. hope i helped!
(sorry if wrong)
Answer:
Maximum height attained by the ball will be h = 28.416 m
Explanation:
We have given initial speed of the ball u = 23.6 m /sec
At maximum height velocity will be zero so final velocity v = 0 m/sec
Acceleration due to gravity 
From law of motion we know that 
h = 28.416 m
So maximum height attained by the ball will be h = 28.416 m
