Answer:
a. What is the wavelength?
The wavelength is 5 meters.
b. What is the frequency?
The frequency is 0.05Hz
c. What is the wave velocity?
The wave velocity is 0.25 meters per second
Explanation:
the wavelength is the distance between two troughs or two crests, which in this case is 5 meters.
the frequency=cycles/time. For this equation the equation would be 1/20, which is 0.05
the wave velocity=wavelength x frequency. Plug in the numbers, 5 x 0.05, and you will get 0.25.
Answer:
Thanks! :) Have a great day!
Explanation:
Answer:
An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.
Answer:
Covalent bonds.
Explanation:
Covalent binds where electrons are shared between the H and O atoms.
