Answer:
Distance / Time = Speed
Explanation:
This is because you want to see how much distance you cover within a time interval.
For example, MPH, is a unit for speed, which is miles (distance) per hour (time)
The resultant force is 4 N to the right.
A) Metal expand upon heating. B) Alloys expand less upon heating than elemental metals. C) Alloys expand more upon heating than elementals metals. D) The rate of the expansion of metals is directly proportion to the temperature to which it is heated
Answer:
Wavelength
Explanation:
The distance between corresponding points of adjacent waves is known as the wavelength.
In a wave motion, the point at which displacement is at maximum is known as the crest of the wave while the point where the displacement is at minimum is known as the trough of the the wave.
The distance between these two successive crest and trough of he wave as known as its wavelength.
Wavelength can be expressed as a function of frequency and velocity of a wave.
