A surface wave is a wave in which particles of the medium undergo a circular motion.
Answer:
The answer is a, the dirty cloths, water and detergent.
Explanation:
The answer is the above selected because the inputs basically represent the data that are passed through the system to generate the output.
In this case, the inputs are the aforementioned in the answer while the possible output would literally be the clean cloths.
First electromagnet
Explanation:
The first electromagnet is the strongest and it is stronger than the given electromagnet above.
An electromagnet is a temporary magnet made by passing current through a wire wounded round an iron core or metallic core.
- When current is passed through, the metal becomes magnetic.
- The strength of the electromagnet depends on the number of coil round the metal core and also the intensity of current passed through it.
- The higher the number of coils wounded round the metal core, the stronger the electromagnet that will be produced.
- Also, the higher the intensity of electricity passed through the wire, the stronger it is.

hey guy
the vibration per second is frequency
then for 20 vibration time taken is 100 second
in 1 second 20/100 vibration took place
it means 0.2 is frequency
for time period , we have
t=1/f
=1/0.2
=5
