<h3><u>Answer;</u></h3>
<em>B. The wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.</em>
<h3><u>Explanation;</u></h3>
- <em><u>Longitudinal waves are waves in which the vibration of particles is parallel to the direction of the wave motion.</u></em> The vibration of particles generates regions known as compressions and rarefactions. Therefore<em> </em><u><em>the wavelength is the distance between two successive rarefactions or compressions.</em></u>
- <u><em>Transverse waves on the other hand are those waves in which the vibration of particles is perpendicular to the direction of the wave motion. </em></u>The vibration of particles generates regions of maximum displacement called crests and regions of minimum displacement called troughs. Thus, <em><u>the wavelength is the distance between two successive crests or troughs.</u></em>
Answer:
12.5 m.
Explanation:
Speed: This can be defined as the rate of change of distance. The S.I unit of speed is m/s. Mathematically it can be expressed as,
Speed = distance/time
S = d/t......................... Equation 1
d = S×t ...................... Equation 2.
Where S = speed of the car, d = distance, t = time taken to shut the eye during sneezing
Given: S = 90 km/h, t = 0.50 s.
Conversion: 90 km/h ⇒ m/s = 90(1000/3600) = 25 m/s.
S = 25 m/s.
Substitute into equation 2.
d = 25×0.50
d = 12.5 m.
Hence the car will move 12.5 m during that time
