Air gap means that the dielectric is air.
So <span>ε0 = </span><span>8.85 x 10^-12 [F/m].......................permitivity of free space
Lets use the equation
</span>C= ( ε0x A) / d
Where A is the area of the plate
And d the distance between the plates
d = <span>3.2-mm = 3.2 E-3 m
so ............> A = C *d /</span>ε0 = 0.20 F * 3.2 E-3 m / 8.85 x 10^-12 [F/m]
A = 7.23 E 7 [m2]
Newton's first law actually states that a force isn't needed to keep an object moving, so no.
Answer:
here is explanation
Explanation:
Proxima Centauri The closest star to our own Is still 40,208,000,000,000 km away.
(OR ABOUT 268,770 AU)
A sloping line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object. The steeper the line (and the greater the gradient) the faster the object is moving.
