Frictional force always opposes applied force, so the net force on the cart would have to be 19N - 1.7N. The acceleration can then be solved by using the relation: F = ma. This is shown below:
Net force = 19 - 1.7 = 17.3 N
Acceleration = Force / mass
Acceleration = 17.3 / 2
Acceleration = 8.65 N/m

(I'm not 100% sure, let me know if I made a mistake :))
Answer:
All matter contained electrons
Explanation:
The discovery and characterization of cathode ray suggested that it was a subatomic particle and cathode ray ( electron) was the first discovered. It immensely became the strong explanatory tool for chemical bond. This can be attributed to the the ease with which electron move from one atom to the other.
Ceq in series is calculated by 1/C1 + 1/C2 + ....
While, in parallel, Ceq= C1 + C2 + ...
So the ratio is 1/Ceq = Ceq
