Answer:
True
Explanation:
As frequency increases, the length of the wave (period) decreases.
As frequency decresaes, the length of the wave (period) increases.

Answer:
speed
Explanation:
its the speed
because the formula for deriving speed is distance/time
the unit for distance is metre
the unit for time is seconds
so speed is metre/seconds
so speed us m/s.
Answer:
18.14m
Explanation:
Given parameters:
Frequency = cycles/s
Speed of wave = 57m/s
Unknown:
Wavelength = ?
Solution:
The speed of a wave is related to frequency and wavelength using the expression below;
V = f x λ
V is the speed of the wave
f is the frequency
λ is the wavelength
Insert the parameters and find λ;
57 = x λ
λ = 57 x = 18.14m
Answer:
25000J
Explanation:
Formula : Q = m×c×Δt
Q=Heat energy
m= mass
c=specific heat capacity
ΔT = change in temperature.
Q=M x C for this question.
Specific heat capacity = 2500 J/Kg
Mass = 10kg
2500 x 10 = 25000 J
If stretching is done during the cool-down it should help the muscles with increased flexibility.
