An inductor is connected in series to a fully charged capacitor. which of the following statements are true?

Physics

enot [183]4 years ago

The true statements would be ; the stored field energy can be greater than the stored magnetic field energy, the stored electric field energy can be equal to the stored magnetic field energy, As the capacitor is discharging, the current is increasing and the stored electric field energy can be less than the stored magnetic field energy. A capacitor in a series circuit with a resistor charges by passing charges through the resistor. As charging proceeds, the p.d across the capacitor increases until it reaches the value of the supply voltage. When a capacitor is charged it stores energy, which it can supply to other components when it discharges.

The maximum tension that a 0.80 m string can tolerate is 15 N. A 0.35-kg ball attached to this string is being whirled in a vert
zimovet [89]

Answer:

v=5.86 m/s

Explanation:

Given that,

Length of the string, l = 0.8 m

Maximum tension tolerated by the string, F = 15 N

Mass of the ball, m = 0.35 kg

We need to find the maximum speed the ball can have at the top of the circle. The ball is moving under the action of the centripetal force. The length of the string will be the radius of the circular path. The centripetal force is given by the relation as follows :

F=\dfrac{mv^2}{r}

v is the maximum speed

v=\sqrt{\dfrac{Fr}{m}} \\\\v=\sqrt{\dfrac{15\times 0.8}{0.35}} \\\\v=5.86\ m/s

Hence, the maximum speed of the ball is 5.86 m/s.

The element in a fluorescent lightbulb that absorbs UV light and releases visible light energy is ____?
Mnenie [13.5K]
So in a fluorescent light bulb the mercury atoms release the UV light. This UV light is absorbed by the phosphorous powder coating inside and this releases the visible light.
So your answer is phosphorous powder.
