<span>-- the product of the net charges on the objects;. -- the distance between the centers of their net charges. (Pretty much identical to the formula for gravitational force)</span>
Wait what? I can’t understand. But here is what I understood. About how long does it take the Earth to make 1 revolution around the sun? Answer: 365 days
We know from the physics class that the time is simply the
distance divided by velocity:
time = distance / velocity
Substituting the given values and calculating for time:
time = 360 km / (72 km / hour)
time = 5 hours
<span>Therefore it takes the train 5 hours to arrive.</span>
<span> the answer is a Radiosonde</span>
