Answer:
The radius of the circular plate is 0.774 m
Explanation:
Given;
distance between the parallel plates, d = 1.53 cm = 0.0153 m
electric field energy density between plates,
= 4.41 J/m³
Potential energy of the capacitor,
= 0.127 J
Energy density is given as;
![U_E = \frac{U_c}{V}](https://tex.z-dn.net/?f=U_E%20%3D%20%5Cfrac%7BU_c%7D%7BV%7D)
where;
V is volume
![V = \frac{U_c}{U_E} = \frac{0.127}{4.41} = 0.0288 \ m^3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7BU_c%7D%7BU_E%7D%20%3D%20%5Cfrac%7B0.127%7D%7B4.41%7D%20%3D%200.0288%20%5C%20m%5E3)
Volume is given as;
V = Ad
where;
A is area
A = V / d
A = (0.0288) / (0.0153)
A = 1.882 m²
Area of circular plate is given as;
A = πr²
where;
r is the radius of the circular plate
![r = \sqrt{\frac{A}{\pi} } \\\\r = \sqrt{\frac{1.882}{\pi}}\\\\r = 0.774 \ m](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%5Cfrac%7BA%7D%7B%5Cpi%7D%20%7D%20%5C%5C%5C%5Cr%20%3D%20%5Csqrt%7B%5Cfrac%7B1.882%7D%7B%5Cpi%7D%7D%5C%5C%5C%5Cr%20%3D%200.774%20%5C%20m)
Therefore, the radius of the circular plate is 0.774 m
Answer:
Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving
Answer:
The difference between the lower mantle and the oceanic crust is first their respective locations, pressure and temperature-- the pressure and temperature increases with depth in the earth this the mantle is more hot and under great pressure than the crust.
Explanation:
Answer:
The number of turns present in the loop are 625 turns.
Explanation:
Given;
current on the rectangular loop, I = 6A
Dimension of the rectangular loop, L x B = 0.04 m × 0.08 m
Magnetic moment of the loop, Pm = 12 Am²
Area of the rectangular loop, A = L x B = 0.04 m × 0.08 m = 0.0032 m²
The magnetic moment of plane carrying coil/loop is given as;
Pm = NIA
Where;
N is the number of turns
A is the area of the loop
I is the current on the loop
![N = \frac{P_m}{IA} \\\\N = \frac{12}{6*0.0032}\\\\N = 625 \ turns](https://tex.z-dn.net/?f=N%20%3D%20%5Cfrac%7BP_m%7D%7BIA%7D%20%5C%5C%5C%5CN%20%20%3D%20%5Cfrac%7B12%7D%7B6%2A0.0032%7D%5C%5C%5C%5CN%20%3D%20625%20%5C%20turns)
Therefore, the number of turns present in the loop are 625 turns.
