Are sound waves transverse waves or longitudinal waves? Why?
aleksandrvk [35]

Answer: Longitudinal Waves

Explanation: The particles of the medium pass parallel to the course that the heart beat moves. This sort of wave is a longitudinal wave. Longitudinal waves are usually characterised through particle motion being parallel to wave movement. A valid wave traveling thru air is a classic example of a longitudinal wave.

Một sóng cơ học có tần số 50hz lan truyền dọc theo một sợi dây rất dài biết rằng sau 5 giây sóng truyền được 1 đoạn 25m dọc theo
Oliga [24]

Answer:

10 cm

Explanation:

Được

Tần số = 50 hertz

Khoảng cách đã đi = 25 m

Thời gian đi quãng đường 25 m = 5 giây

Tốc độ của sóng = 25/5 = 5 mét trên giây

Như chúng ta biết

Bước sóng = Vận tốc / tần số

Bước sóng = 5 mét trên giây / 50 trên giây

Bước sóng = 0,1 m = 10 cm

A capacitor is connected to an ac generator. As the generator’s frequency is increased, what happens to the capacitor connected
Bad White [126]

Answer:

Current in the capacitor increases as the frequency of the generator increases

Explanation:

Xc = 1/2πfC = 1/ wC

Since frequency is inversely proportional to reactance of a capacitor,

as the frequency increases, the capacitance decreases and tend towards behaving like a wire with zero resistance as such the generator send high current to the capacitor, the current in the capacitor increases.
