Answer:
D. They don't require a medium to travel through.
Explanation:
Electromagnetic waves and mechanical waves are both types of waves. Electromagnetic waves are waves that arise from the combination of electric and magnetic fields while mechanical waves are waves that arise as a result of transfer of energy via matter.
One major difference between these two types of waves is that electromagnetic waves such as light waves, radiowaves etc. do not need a medium to travel i.e. they can travel through a vacuum, while on the other hand, mechanical waves such as sound waves need a medium to travel.
9*9=81 ,a good way to remember is 9 times 2 is 18 so u just flip it
I think the answer its false i dont know how to explain that but it is false that what my teacher told me
Answer:
The person will travel 24 meters.
Explanation:
Distance = Rate * TIme
Distance = d = ?
Rate = r = 6 m/s
Time = t = 4 seconds
d = r*t = (6 m/s)*(4 seconds)
d = 24 m
**Note that the units (m/s) and (s/1) cancel to leave the answer in meters, the desired unit**
