Answer:
Most electric charge is carried by the electrons and protons within an atom. Conversely, two protons repel each other, as do two electrons. Advertisement. Protons and electrons create electric fields, which exert a force called the Coulomb force, which radiates outward in all directions.

Explanation:
a) The maximum possible acceleration that the truck can give to the SUV is:
![a_{max} = \frac{18,000\,N}{2,400\,kg+2300\,kg}](https://tex.z-dn.net/?f=a_%7Bmax%7D%20%3D%20%5Cfrac%7B18%2C000%5C%2CN%7D%7B2%2C400%5C%2Ckg%2B2300%5C%2Ckg%7D)
![a_{max} = 3.8\,\frac{m}{s^{2}}](https://tex.z-dn.net/?f=a_%7Bmax%7D%20%3D%203.8%5C%2C%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D)
b) The equation of equilibrium for the truck is:
![18,000\,N - F = (2,300\,kg)\cdot (3.8\,\frac{m}{s^{2}})](https://tex.z-dn.net/?f=18%2C000%5C%2CN%20-%20F%20%3D%20%282%2C300%5C%2Ckg%29%5Ccdot%20%283.8%5C%2C%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%29)
The force of the SUV's bumper on the truck's bumper is:
![F = 9260\,N](https://tex.z-dn.net/?f=F%20%3D%209260%5C%2CN)
Answer: 4
Explanation: when you're solving velocity you should divide the two numbers so 16/4=4
