Answer:
Mass of car = 1098 kg
Explanation:
Here law of conservation of momentum is applied.
Let mass of car be m.
Initial momentum = Final momentum.
Initial momentum = 4350 x 7.39 + m x 0 = 32416.5 kgm/s
Final momentum = 4350 x 4.55 + m x 11.5 = 19792.5+11.5m
We have
19792.5+11.5m = 32416.5
m = 1097.97 kg
the eletrical forces are created when an object is both moving charges and stationary charges.
the magnetic forces are created when an act on only moving charges.
Black. or a dark brown.
This could be wrong but I am giving a decent suggestion: All ions are atoms with a negative charge.
