Explanation:
Let us assume that the separation of plate be equal to d and the area of plates is
. As the capacitance of capacitor is given as follows.
C = 
It is known that the dielectric strength of air is as follows.
E = 
Expression for maximum potential difference is that the capacitor can with stand is as follows.
dV = E × d
And, maximum charge that can be placed on the capacitor is as follows.
Q = CV
= 
= 
= 
= 
or, = 10.62 nC
Thus, we can conclude that charge on capacitor is 10.62 nC.
Answer:250.03m
Explanation:
Initial velocity =u=51mph
Angle=β=37
Acceleration due to gravity=g=10
The distance covered by the football is the range
Range=(u^2xsin2β)/g
Range=(51^2xsin(2x37))/10
Range=(51x51xsin74)/10
Range=(2601xsin74)/10
Range=(2601x0.9613)/10
Range=(2500.3)/10
Range=250.03m
Answer:
Both wires have the same resistivity.
Explanation:
The resistivity of a material depends on the following factors:
- The nature of the material, i.e., the number density of free electrons of the material.
- The temperature of the material.
The resistance R of a wire of resistivity
, length l and cross-sectional area A is given by

On varying the length and cross-sectional area of the wire, the resistance of the wire is changed but resistivity does not change as it is an intrinsic property of the material of the wire.
For the two given wires, the length and the cross-sectional area are different, but both the wires are of copper which means the number density of free electrons on both the wires is same and both the wires are placed in same environmental condition, which means the temperature would also be same.
Thus, the resistivities of both the wire are same.
