Answer:
Explanation:
1 . The two busses continue together at the same speed.
FALSE STATEMENT .
The small bus will have twice the velocity of bigger bus velocity in the same direction . The bigger bus will continue with the same velocity .

TRUE STATEMENT.
3 The small bus exerts the same amount of force on the big bus as vice versa.
TRUE STATEMENT.
4.Momentum is conserved
TRUE STATEMENT.
5.The small bus will go backwards
FALSE STATEMENT .
The small bus will have twice the velocity of bigger bus velocity in the same direction .

Explanation:
distorts or shears rock as it travels through it
Answer: a = 1.32 * 10^18m/s² due north
Explanation: The magnitude of the force required to move the electron is given as
F = ma
The force exerted on the charge by the electric field of intensity (E) is given by
F = Eq
Thus
Eq = ma
a = E * q/ m
Where a = acceleration of charge
E = strength of electric field = 7400N/c
q = magnitude of electronic charge = 1.609 * 10^-6c
m = mass of an electronic charge = 9.109 * 10^-31kg
a = 7400 * 1.609 * 10^-16/ 9.109 * 10^-31
a = 11906.6 * 10^-16 / 9.019 * 10^-31
a = 1.19 * 10^-12 / 9.019 * 10^-31
a = 0.132 * 10^19
a = 1.32 * 10^18m/s²
As stated in the question, the direction of the electric field is due north hence, the direction of it force will also be north thus making the electron experience a force due north ( according to Newton second law of motion)
