کسی چیز کی تیزی سے آگے پیچھے حرکت کو کیا کہا جاتا ہے؟
A. Translation
B. Rotation
C. Revolution
D. Vibration
Explanation
Vibration refers to the rapid back and forth movement of an object, often in a repeating pattern. This can include motions like oscillations, shakes, or tremors.
Show/Hide Explanation
A. T=2π√k1+k2/m
B. T=2π√m/k1
C. T=2π√m/k1+k2
D. None of these
Explanation
When two springs are connected in parallel: Effective spring constant (k) = k1 + k2
Time period (T) = 2π√(m / k)
= 2π√(m / (k1 + k2))
Show/Hide Explanation
A. U
B. U/2
C. U/√2
D. U/(2π)
Explanation
In an oscillating LC circuit, the maximum energy stored in the capacitor during one cycle is equal to the total stored energy (U) in the circuit.
This is because the total energy oscillates between the capacitor and the inductor, with the total energy remaining constant in an ideal, lossless LC circuit.

دولن کی کل توانائی ______ پر منحصر ہے؟
A. Frequency
B. None of these
C. Amplitude
D. Square of the amplitude
Explanation
In simple harmonic motion , the total energy (E E A 2 A^2 Total energy is given by E = 1 2 k A 2 E = frac{1}{2} k A^2 , where k k is the spring constant.

سادہ ہارمونک حرکت میں، سرعت زیادہ سے زیادہ ہوتی ہے جب ______؟
A. None of these
B. Velocity is maximum
C. Displacement is zero
D. Displacement is maximum
Explanation
In SHM , acceleration is directly proportional to displacement and is maximum at the extreme positions. At maximum displacement , restoring force is also maximum, leading to maximum acceleration. Show/Hide Explanation
