Answer:
Explanation:
Capacitance of the capacitor
C = ε₀ A / d
(8.85 x 10⁻¹² x .25² x 10⁻⁴) / 1 x 10⁻³
C = .553125 x 10⁻¹³ F
Charge = capacitance x volt
= .553125 x 10⁻¹³ x 1.5
= .8296875 x 10⁻¹³ C
no of electrons
= charge / charge on one electron
= .8296875 10⁻¹³/ 1.6 x 10⁻¹⁹
= 5.2 x 10^5
Answer:
Torque = -1799.52 Nm or 1799.52 Nm (clockwise direction)
Explanation:
Torque = Force x Perpendicular distance
Here force is given as 18.4 N and Perpendicular distance = 97.8 m
Substituting
Torque = Force x Perpendicular distance = 18.4 x 97.8 = 1799.52 Nm
Torque = 1799.52 Nm (clockwise direction)
Usually anticlockwise is positive
So torque = -1799.52 Nm
Answer: 60 times brighter
Answer:
6 amps
Explanation:by Kirchhoff's loop rule the current at any point in the loop must be equal or charge would be building up. The current at the ammeter is equally to the total current through the sun of the paths in parallel which it is in series with
