f = 40 Hertz
Explanation:
Velocity of a wave = frequency × wavelength
frequency = velocity/wavelength
20m/s = f × 0.50
20/0.50 = f
40 Hertz = f or f = 40 Hertz
The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. Thus, the amount of matter cannot change.
The answer could be a satellite
Temperature Decreases
Pressure Increases
Salinity Increases
A chemical reaction is a process that can lead to a change of state, the outcome of a chemical reaction can ultimately lead to the formation of a new substance.
