Answer:
wavelength
Explanation:
the definition of wavelength is the distance between two consecutive waves. with that being said, the point from the crest of one wave to the crest of another would be wave length
Answer:
h = 15.34 m
Explanation:
given,
tuning fork vibration = 513 Hz
speed of sound = 343 m/s
frequency after deflection = 489 Hz
the source (the fork) moves away from the observer, its speed increases and hence the apparent frequency decreases
u = 16.92 m/s
height of the building
v² = u² + 2 g s
16.92² = 2 x 9.8 x h
h = 14.61 m
time taken by sound to reach observer
in this time tuning fork has fallen one more now,
h' = 0.7296 m = 0.73 m
total distance
h = 14.61 + 0.73
h = 15.34 m
The electric field strength of a uniform electric field is constant throughout the field. A perfectly uniform electric field has no variations in the entire field and is unattainable in the real world. However, two parallel plates can generate a field that resembles a perfectly uniform field with slight variations near the edge of the plates. <span>Electric fields are represented by drawing field lines that represent the direction of the field, as well as the strength of the field. More field lines represents a higher field strength. In a non-uniform electric field, the field lines tend to be curved and are more concentrated near the charges. In a uniform electric field, since the field strength does not vary, the field lines are parallel to each other and equally spaced. Uniform fields are created by setting up a potential difference between two conducting plates placed at a certain distance from one another. The field is considered to be uniform at the center of the plates, but varies close to the edge of the plates. The strength of the field depends on the potential difference applied to the plates and the distance by which they are separated. A higher potential difference or voltage results in a stronger electric field. The greater the distance between the plates, the weaker the field becomes. The electric field is therefore calculated as a ratio of the voltage between the plates to the distance they are separated by.</span>
