B is the correct answer i guess
Answer:
45 N
Explanation:
F= ma (ie force is found by multiplying the mass of the object by its accerelation)
thus, F = 15 X 3 = 45 N
When any component is short-circuited, the component becomes irrelevant. Resistance between it’s terminals becomes zero irrespective of value of the component. In other words, capacitance ceased to exist.
For the circuit containing such capacitor, situation is somewhat like capacitor with infinite capacitance. However as the capacitor can not hold any charge, we can say that it is not not equivalent of infinite capacitance, because the capacitor can not hold any charge.
Hence we can say that the capacitance just vanishes, when the plates are joined together by a connecting wire.

Answer:
Momentum = 9kgm/s
Explanation:
Given the following data;
Mass = 18kg
Velocity = 0.5m/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Substituting into the equation, we have;
Momentum = 18 * 0.5
Momentum = 9kgm/s
Therefore, the momentum of the object is 9kgm/s.
