Answer:
Explanation:
The capacitor of a parallel-plate capacitor is given by:
where
A is the area of each plate
d is the separation between the plates
is the vacuum permittivity
The energy stored in a capacitor instead is given by
where
Q is the charge stored in each plate
Substituting the expression we found for C inside the last formula,
And re-arranging it
Now if we substitute
We find the charge stored on the capacitor:
F = m × g
Now when, a force acts on the object at an angle and in downwards, thus formula becomes:
= N = mg + F sin(x)
Here,
See, as we habe to calculate the weight, which is m × g, thus we will recreate thus formula like thus:
= N = w + F sin(x) --------- [Weight = w]
Now, the solutions becomes easy from here, just put the values:
= N = w + F sin(x)
= 200 = w + 90 × sin(32)
= 200 = w + 90 × 0.55
= 200 = w + 49.5
= 200 - 49.5 = w
= 150.5 = w
I have got my answer but in approx, hope you will not mind. ^^"

T = Normal temperature =
l = Width to be left for expansion
= Coefficient of linear expansion of the material =
= Maximum temperature =
= Change in temperature =
The expression of linear expansion is given by
The expression for the minimum gap distance l the engineers must leave for a track rated at temperature is
Answer:
Force of Kgm/s^2 must be applied to the piston to raise oil to a height of 6.0 m
Explanation:
As we know,
Pressure is the force per unit area
Or
Force
Pressure is the product of density, gravitational constant and height
Force
Kgm/s^2
