Hi there!
There are 5,280 ft in a mile so multiply that by 60
5,280 × 60 = 316,800 ft
There are 60 min in an hour and 60 sec in a minute so multiply 60 sec by 60 sec
60 sec × 60 min = 3600 sec
Now divide 316,800 ft by 3600 sec to get:
316,800 ft ÷ 3600 sec ≈ 88 (ft/s)
Answer:
C. tiny particles called charges flowing through the wires.
Explanation:
<h3> Hello!</h3>
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.
Hope it helps!

In SI units with dry air at 20*C (68*F), the speed of sound c is 343 meters per second (m/s).
The answers is 343 meters per second:
Answer: 10.2 kg if g = 9.8, 10 if g = 10.
Explanation:
Weight or the "force of gravity" on a person is simply defined by the equation: F = ma. In this case, the acceleration is g, which is 9.8 but can be rounded up to 10. Based on this, we have:
F = mg
100 = m*9.8
m = 10.2(or 10 if we set g to 10).
