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
The final speed of the cart and the bag is 2.2 m/s
Explanation:
We can solve this problem by using the law of conservation of momentum: in fact, in absence of external forces, the total momentum of the bag and the cart must be conserved before and after the collision.
Mathematically:
where:
is the mass of the bag of rice
is the initial velocity of the bag
is the mass of the cart
is the initial velocity of the cart (at rest)
is the final combined velocity of the bag and the cart
Re-arranging the equation and solving for v, we find:

Answer:
6.96 s
Explanation:
The period of a simple pendulum is given by:

where
L is the length of the pendulum and g the acceleration due to gravity.
In this problem, we have a pendulum with length L = 2.00 m, while the acceleration due to gravity is 1/6 that of the earth:

So, the period of the pendulum on the moon is

Bulbs c and b would still be screwed in if they were in to begin with and bulbs A, D, and E. would be unscrewed
