Answer: Option B.) they travel from south to north
Inside the magnet, the field lines travel from South to North.
Explanation:
A magnet has two poles: North and South. The magnetic field lines originate from North and end at south pole. Maximum field lines are at the poles. Inside the magnet, the field lines travel from South pole to North pole. Overall, the field lines form a loop.
Answer:
Explanation:
wavelength, λ = 2.5 m
speed, v = 13.8 m/s
Amplitude, A = 0.14 m
The general equation of the transverse harmonic wave which is travelling right is given by
where, Ф is phase
At t = 0, x = 0 , y = 0.14 m
0.14 = 0.14 Sin Ф
Ф = π/2
So, the equation is
The tension in the swing's chain at the bottom of the swing is 178.35 N.
The given parameters:
The tension in the swing's chain at the bottom of the swing is calculated as follows;
Thus, the tension in the swing's chain at the bottom of the swing is 178.35 N.
