- Frequency ( f ) : The number of complete waves , set up in a medium in one second is called frequency of the wave. The SI unit of frequency is Hertz ( Hz ). For example : if a sound wave completes 15 compressions and 15 rarefactions in one second , it's frequency is 15 Hz.
- Wavelength ( λ ) : The distance between two consecutive troughs or crests in a transverse wave or the distance between two consecutive compressions or rarefactions in a longitudinal wave us called wavelength. It is the distance travelled by a wave in a time equal to it's time period. It's SI unit is metre ( m ).
- Wave velocity ( v ) : The velocity with which a wave propagates in a medium is called wave velocity. It's SI unit is m/s.

Explanation:
mars has a shorter year because when it revolves around the sun, it takes less time than, saturn who is millions of miles away from mars, longer. Also, mars is closer to the sun than saturn
Answer:
1.63 m/s
Explanation:
a = acceleration of the ball
d = stopping distance = 23.5 - 5.10 = 18.4 ft = 5.61 m
v₀ = initial velocity of the car = 1.45 m/s
v = final velocity of the car = 0 m/s
Using the equation
v² = v₀² + 2 a d
0² = 1.45² + 2 a (5.61)
a = - 0.187 m/s²
To win the tournament :
a = acceleration of the ball = - 0.187 m/s²
d = stopping distance = 23.5 ft = 7.1 m
v₀ = initial velocity of the car = ?
v = final velocity of the car = 0 m/s
Using the equation
v² = v₀² + 2 a d
0² = v₀² + 2 (- 0.187) (7.1)
v₀ = 1.63 m/s
