Answer:
mj = 53.3kg
Explanation:
Since both gravitational energies are the same:
Eb = Ej => mb*g*hb = mj*g*hj
Solving for mj:
mj = mb*hb/hj = 80*2.4/3.6
mj = 53.3kg
1. Find the spring constant k:
F = mg = kx
68 * g = k * 0.0055m
k = 121287.273
2.Find the frequency f:
ω = 2πf = √k/m
f = √(k / m)/ 2π = 1.7
According to the right hand grip rule; if you point your right thumb in the direction of the current flow and curl your fingers around the current carrying conductor, the fingers will point in the direction of the circular magnetic field around the conductor. Therefore,if the the current carrying carrying conductor is held with the current flowing towards you, using right hand grip rule the lines of magnetic field will act towards a counterclockwise direction or anticlockwise direction.
Making a wire thicker has the same effect as making a road wider. It makes it easier for the electron traffic to flow. The resistance decreases, and the current (traffic) increases.
Answer:
Capacitive Reactance is 4 times of resistance
Solution:
As per the question:
R = 
where
R = resistance

f = fixed frequency
Now,
For a parallel plate capacitor, capacitance, C:

where
x = separation between the parallel plates
Thus
C ∝ 
Now, if the distance reduces to one-third:
Capacitance becomes 3 times of the initial capacitace, i.e., x' = 3x, then C' = 3C and hence Current, I becomes 3I.
Also,

Also,
Z ∝ I
Therefore,




Solving the above eqn:
