When an ebonite is rubbed with animal fur, the rod becomes negatively charged. Why? A) positively charges are tranferrer from tje fur to the rod

B) negative charges are created on the surface of the rod

C) negative charges are tranferred from the rod to the fur

D) negative charges are transfrerred from the fur to the rod

E) Positive charges are transferred from the rod to the fur

Please help.

is there any options? maybe im just not seeing them but i need the options to

(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
