Answer:
Zero
Explanation:
here, the inductive reactance and the capacitive reactance is same, so this is the condition for resonance.
In the condition for resonance,
the circuit and the voltage in the circuit is in the same phase and the impedance of the circuit is minimum which is equal to the resistance of the circuit.
The phase angle is given by
Ф = 0
Answer:
t=L/
Explanation:
<u>solution:</u>
Let E be an observer, and B a second observer traveling with velocity as measured by E. If E measures the velocity of an object A as
then B will measure A velocity as
=
-
Applied here,
the walkway (W) and the man (M) are moving relative to Earth (E}, the velocity of the man relative to the moving walkway is
=
-

The time required for the woman, traveling at constant speed relative to the ground, to travel distance L relative to the ground is
:
t=L/
Answer:
The magnitude of the torque due to gravity if it is supported at the 28-cm mark is 0.5 N-m.
Explanation:
Given that,
Mass of the meter stick, m = 0.3 kg
Center of mass is located at its 45 cm mark.
We need to find the magnitude of the torque due to gravity if it is supported at the 28-cm mark. Torque acting on the object is given by :
or
So, the magnitude of the torque due to gravity if it is supported at the 28-cm mark is 0.5 N-m.
