Answer:
d' = d /2
Explanation:
Given that
Distance = d
Voltage =V
We know that energy in capacitor given as
If energy become double U' = 2 U then d'
2 d ' = d
d' = d /2
So the distance between plates will be half on initial distance.
<h2>Positive Affects:</h2>
- Technology aids in the research of curing diseases or other environmental problems. Without technology, we would not have been able to eradicate diseases like polio.
- Technology allows us to communicate to people quicker, in spite of the distance and conditions.
<h2>Negative</h2>
- Over-dependence of technology makes humans lazy. We won't be paying much attention because everything is available on Google.
- There are health affects due to the radiation. Our vision gets weakened and the laziness can lead to physical problems like obesity and fatigue.
Explanation:
No matter where you are in the universe, your mass is always the same: mass is a measure of the amount of matter which makes up an object. Weight, however, changes because it is a measure of the force between an object and body on which an object resides (whether that body is the Earth, the Moon, Mars, et cetera).
Only Condition for Resonance is-
It occurs when the first object is vibrating at the natural frequency of the second object. It always result into a big vibration/loud sound.
Resonance is process by which a vibrating system or an external force drives another system to oscillate with greater frequencies at specific frequencies called resonant frequencies. At resonance frequencies, small periodic driving forces have capacity to produce large amplitude oscillation.
∴ In given scenarios, the case which accurately describes a condition in which resonance can occur is-
C. A pipe's length is equal to 1⁄2 of the wavelength of the sound waves produced by a tuning fork vibrating over one end of the pipe that's open to the air at both ends.
