Answer:-1000
Explanation:
Since the speeds are the same and only the weight is different. You have to subtract 2000 from 1000 because mm is hitting 1000 which this means that 1000 - 2000 because they're crashing into each other it equals negative 1000
Answer:
The awnser for "Electricity that flows in a closed path is called a" circuit.
Potential difference= current x resistance
so current = potential difference÷resistance
current =3÷120 (two bulbs 60+60)
current =0.025A
