Ответ:
A horizontal line on a speed-time graph represents a constant speed.
Explanation:
Acceleration is defined by a sloping line on a speed-time graph. The sloping line shows the object's speed is increasing. The target either accelerates or slows down.
Velocity-time graphs are being used to illustrate the acceleration for moving objects in a horizontal path. You can use them to display momentum and to sort out movement.
Ответ:
Where f is the frequency in Hertz, wavelength is in meters.
Speed, v = 2*5 = 10
Speed = 10 m/s.
