Answer:
a) T = 2.997 s
b) K = 14.3 J
c) φ = 0.444 rad
Explanation:
a) Determine its period
The pendulum simple’s period is:
T = 2π
Where l: Pendulum’s length
g = 9.8 m/s2
T = 2π
T = 2.997 s
b) Total energy
Initially his total energy is kinetic
K = 
K = 
K = 14.3 J
c) Maximum angular displacement
φ = 
φ = 
φ = 0.444 rad
The average current density in the wire is given by:
where I is the current intensity and A is the cross-sectional area of the wire.
The cross-sectional area of the wire is given by:
where r is the radius of the wire. In this problem, 
, so the cross-sectional area is
and the average current density is
Explanation:
I = 120/30=2A
Voltage across R3= current × resistance
= 2A × 15 ohm = 30 volt
