The space between them is shrinking at (60+40)= 100 mph. It started out being 120 miles. To shrink to zero will take
(120 miles) / (100 mph) = 1.2 hours
That's 1 hour and 12 minutes.
Answer:
0.015m^3
Explanation:
1 m^3 = 1000 liters
x m^3 = 15 liters
Cross multiply
xm^3 x 1000 l = 15 l
Divide both sides by 1000
xm^3 x1000/1000 = 15/1000
xm^3 = 0.015m^3
Therefore 15 liter = 0.015m^3
The answer to your question is A.
-identifies an electric charge
-it can identify its polarity (positive or negative) if you compare it to a charge that you already know
