The speed of a wave is calculated by multiplying the frequency by the wavelength. For a wave with a frequency of 2Hz and a wavelength of 4m, the speed is 8m/s.
The subject of your question is Physics, specifically the behavior of waves. The speed of a wave can be calculated using the equation speed = frequency ×wavelength. Given that the frequency of your wave is 2Hz (hertz) and the wavelength is 4m (meters), we substitute these values into our equation.
Thus, the speed of the wave is 2Hz × 4m = 8 m/s. Therefore, the wave is moving at a speed of 8 meters per second.

if you increase either mass or velocity the momentum of an object increases proportionally if you double the mass or velocity you double the momentum.
Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
The momentum is given by:
P=mv
Where P is momentum.
m is mass and v is velocity.
Therefore, the momentum is increased either by increasing mass or velocity.

Answer:
True........................
Yes, it has a speed and a direction, and that makes a velocity. So it's True.
