Answer:
Velocity of wave = 2322 m /sec
Explanation:
We know that, Velocity of wave v = n λ
Given, n
= 540 Hz, λ=4.3 m
, v = ?
Putting the value of n and λ
Velocity of wave = 540 x 4.3 = 2322 m /sec
Answer:
As the masses get larger the force gets larger
Explanation:
Answer:
Se llama ángulo de incidencia -i- el formado por el rayo incidente y la normal. La normal es una recta imaginaria perpendicular a la superficie de separación de los dos medios en el punto de contacto del rayo. El ángulo de reflexión -r- es el formado por el rayo reflejado y la normal.

Answer:
The pulling force F is 200 N
Explanation:
We note that the tension in a rope between two or three blocks is given by the relation;
Where we have;
m₁ → T₁ → m₂ → T₂ → m₃ → F
m₁ = 2 kg
m₂ = 4 kg
m₃ = 4 kg
T₂ = 120 N
Therefore, by substitution, gives;
2 kg → T₁ → 4 kg → 120 N → 4 kg → F
F = 120 N × (10 kg)/(6 kg) = 200 N
The pulling force F = 200 N.
