Answer:
(a). (i). The reactants are .
(II). The inductance of the circuit is 0.1583 Henry.
(b). The resonant angular frequency is 229.4 rad/s.
Explanation:
Given that,
Capacitor = 120.0 μC
Frequency = 200.0 rad/s
Impedance = 100.0 -10j
(I). We need to calculate the
Put the value into the formula
(II). We know that,
Formula of impedance is
...(I)
Given equation of impedance is
...(II)
On Comparing of equation (I) and (II)
Now, put the value of
We need to calculate the inductance
Using formula of inductance
Put the value into the formula
(b). We need to calculate the resonant angular frequency
Using formula of the resonant angular frequency
Hence, (a). (i). The reactants are .
(II). The inductance of the circuit is 0.1583 Henry.
(b). The resonant angular frequency is 229.4 rad/s.
Answer:
Total mechanical energy is the sum of potential energy plus kinetic energy. The kinetic energy will be 250 [J] and the potential energy is zero, therefore Total mechanical energy will be 250 + 0 =250[J]
Explanation:
This is a problem that applies the principle of energy conservation, i.e. mechanical energy that will be transformed into kinetic energy. We need to identify what kind of energy we have depending on the position of the ball with respect to the reference axis we take.
The reference axis or reference point is the point at which the potential energy is equal to zero, for this case we will take the ground as our reference point.
We know that the potential energy is defined by:
We can clear the mass from this equation:
When this body falls its potential energy will decrease but its kinetic energy will increase and reach its maximum value when the ball reaches the ground.
In such a way that its potential energy would be transformed into kinetic energy.
Since the potential energy has been transformed all into kinetic energy the amount of energy is conserved, therefore the total mechanical energy will remain the same.
Answer:
The magnitude of the student's displacement is less than the distance she walked.
Walking: 11 Blocks
Displacement: 8.54 Blocks
Explanation:
See the attached diagram. The unit of length is blocks. We can add the actual blocks walked as shown. She walked a total of 11 blocks.
Her displacement is the distance measured directly from where she started (line A). Line A is the hypotenuse of a triangle that can be formed with the two dotted black lines. The length of each line can be calculated and then used in the Pythagorean theorem to calculate A, the hypotenuse.
That result is 8.54 Blocks, a shorter distance, once she earns her wings.
