Answer:
Explanation:
The capacitance of a parallel-plate capacitor is given by the formula:
where k is the dielectric constant of the material between them, A the area of the plates, d the distance between them and the permittivity, an universal constant.
Since the area of the plates is the product of their sides a=4.3cm=0.043m and b=4.2cm=0.042m, in S.I. we have:
The electrons in a piece of metal will leave when the polarized magnesis effect is reppeled and heated up to a certain tempeture.
Answer:
Option (a)
Explanation:
Given that,
Mass of a car, m = 1200 kg
Force exerted by the engine, F = 600 N
Noe force,F = ma
a is the acceleration of the engine
So, the acceleration of the car is 0.5 m/s².
