Answer:
400 kg.m/s
Explanation:
In a closed system, the principle of conservation of momentum applies. It means. the total momentum before collision equals to the total momentum after collision hence since the initial momentum is given as 400 kg.m/s, the final sum will be the same.
Correct Answers:
- The waves have a trough
- the waves have a crest
- the energy that is transferred move in a perpendicular direction
- particles move in an up and down motion
C. Series
Consider resistors in a circuit - if all the resistors in the circuit are in series and one of the resistors fails then no current can flow thru the circuit,
If the resistors are in parallel then then each resistor experiences the same voltage drop regardless of whether or not any resistor in particular is carrying current.
