Answer:
6g/cm³
Explanation:
Density is the mass per unit volume of any substance. To solve this problem:
Density =
Since mass = 600g
Let us find the volume;
Volume = length x width x height
Volume = 25cm x 2cm x 2cm = 100cm³
Therefore;
Density = = 6g/cm³
Frequency (f) = 500 hz (SI)
Velocity (V) = 1250 m/s (SI)
Wavelength (Lambda) = ? meters
Velocity (V) = 1250 m/s (SI)
Wavelength (Lambda) = ? meters
