Answer:
02.5 N
Explanation:
02.5 N is a derived unit of measurement.
A derived unit is one that is obtained by combining two or more fundamental units.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
Combining the two; kg x m/s² = kgms²
1N = 1 kgms²
kg, m, k and N are fundamental particles
