It is a very reactive metal with 11 protons ,12 neutrons, 11 electrons, and 1 valence electron
Remember that the speed of a wave is the product of both the wavelength and the frequency of the wave.
First convert the units to m and then multiply the values to calculate its propagation or wave speed.
C = lambda • frequency.
Answer:
2 times
Explanation:
Given:
u = 10 m/s
v = 20 m/s
To Find:
Factor of change in Momentum = ?
Solution:
Final Momentum = mv
Final Momentum = m(20)
Final Momentum = 20m
Initial Momentum = mu
Initial Momentum = m(10)
Initial Momentum = 10m
Therefore, Factor of change in Momentum = 20m / 10m = 2 times
