the numbers on the lines.
1. The sensory nerves send the impulse to the brain throu
spinal cord.
2. The receptors (eyes) receive information from the environ
3. The motor nerves carry the impulse the effectors.
4. The brain interprets the impulse.
5. The message goes back to the spinal cord to the motor

the maximum mass of nh3 is nh3 in grams

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
