The wavelength of a water wave is 6 cm when the frequency is 10 hertz .
dedylja [7]

  1. The distance between successive crests (or successive troughs) is defined as the wavelength. The time elapsed between the crossings of two successive crests through a given point is the period of the wave.
  2. The Velocity of propagation (Vp) of a cable is the speed at which an electrical signal can propagate through the cable in comparison to the speed of light. For example, in a vacuum, the velocity of propagation would be 100% or 1 (depending on how it is represented).
  3. The wave period is the time it takes to complete one cycle. The standard unit of a wave period is in seconds, and it is inversely proportional to the frequency of a wave, which is the number of cycles of waves that occur in one second.

A golf ball is struck at 75 m/s at an angle of 60 degrees. What is the
Gnesinka [82]

Answer:

v_x=37.50

Explanation:

The rectangular components of a vector \vec v having a magnitude v and angle θ are:

v_x=v\cos\theta

v_y=v\sin\theta

The golf ball has an initial speed of 75 m/s at an angle of 60 degrees.

The variables of the equations have the values:

v = 75 m/s

θ = 60°

Substituting into the formula:

v_x=75\cos 60^\circ

v_x=75\cdot 0.5

v_x=37.5~m/s

Without specifying units and with precision to the hundredths place:

\mathbf{v_x=37.50}
