(a) The amplitude of the wave is 3 cm.
(b) The speed of the wave is 19.6 m/s
(c) The angular frequency is 653.72 rad/s.
(d) The period of the wave is 0.0096 s.
(e) The wavelength of the wave is 0.392 m.
<h3>
Speed of the wave</h3>
The speed of the wave is calculated as follows;
where;
- μ is mass per unit length = (0.26 kg)/(2 m) = 0.13 kg/m
- T is tension
<h3>Angular frequency</h3>
ω = v/r
ω = v/A
ω = 19.6/0.03
ω = 653.72 rad/s
<h3>Period of the wave</h3>
<h3>Wavelength</h3>
v = fλ
λ = v/f
λ = 19.6/50
λ = 0.392 m

Hello, for this applicate formula:
Vf² = Vo² + 2gh
Data:
Vf = Final Velocity = ¿?
Vo = Initial veloctiy = 0 m/s
g = Gravity = 9,81 m/s²
h = Height = 5 m
Replacing according our data:
Vf² = 0 m/s² + 2(9,81 m/s²)(5 m)
Vf² = 98,1 m²/s²
Vf = √98,1 m²/s²
Vf = 9,9 m/s
The final velocity will be <u>9,9 meters per second.</u>
Answer:
Angle of incidence
Explanation:
When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.
Answer:
For example, a solid may become a liquid. This phase change is called melting. When a solid changes into a gas, it is called sublimation. When a gas changes into a liquid, it is called condensation. ... That allows the solid substance to have a definite volume and shape.

Answer:
0.2 Hz
Explanation:
Frequency: This can be defined as the number of circles completed by a wave in one seconds. The s.i unit is hertz.
From the question,
If 4 Waves arrives on the shore every 20 seconds,
Then,
x waves will arrives on the shore in one seconds
Solving for x
x = (4×1)/20
x = 0.2 Hz
Hence the frequency of the wave is 0.2 Hz
