Answer:
v = 450 m/s
Explanation:
Given data:
Frequency = 75 Hz
Wavelength = 6 m
Velocity = ?
Solution:
Velocity is the product of frequency and wavelength.
v = f × λ
v = 75 Hz × 6 m
Hz = s⁻¹
v = 75 s⁻¹ × 6 m
v = 450 m/s

Answer:
v = 23.96 cm³
Explanation:
Given data:
Mass = 15.0 g
Density = 0.626 g/cm³
Volume = ?
Solution:
Formula:
D=m/v
D= density
m=mass
V=volume
Now we will put the values in formula:
d = m/v
v = m/d
v = 15 g / 0.626 g/cm³
v = 23.96 cm³
