A Transverse Periodic Wave Is Represented by the Equation Y(z

question 54

Multiple Choice

A transverse periodic wave is represented by the equation y(z, t) = −2.0 cm sin(1,200 rad/s t − 20.0 m⁻¹ x) . Another transverse wave is represented by the equation y(z, t) = +2.0 cm sin(1,200 rad/s t + 20.0 m⁻¹ z) . What is the equation that represents the superposition of the two waves?

• A) y(z, t) = 4.0 cm sin(1,200 rad/s t − 20.0 m⁻¹ z)
• B) y(x, t) = 4.0 cm sin(1,200 rad/s t) cos (20.0 m⁻¹ x)
• C) y(x, t) = 4.0 cm cos(1,200 rad/s t) sin (20.0 m⁻¹ x)
• D) y(x, t) = 4.0 cm cos(1,200 rad/s t + 20.0 m⁻¹ x)

Positive Correlation

Positive correlation exists when two variables move in the same direction, meaning that as one variable increases, the other variable also increases.

Negative Correlation

A relationship between two variables in which one variable increases as the other decreases, and vice versa.

Causal Relationship

A connection between two events where one directly results in the occurrence of the other, often determined through correlation and experimentation.
