In a garden, a boy is swinging in the standing position. How will the time period of the swing be affected if the boy sits down on the swing? Time period will depend on the weight of the boy Time period will increase Time period will not change Time period will decrease Question 1 of 12Question 2 of 12 2. A pendulum suspended from the ceiling of a train has a period T when the train is at rest. When the train is accelerating with a uniform acceleration, the period of oscillation will: Become infinite Increase Remain unaffected Decrease Question 2 of 12Question 3 of 12 3. The restoring force of SHM is maximum when particle: Displacement is maximum Half way between them At restCrossing mean position Question 3 of 12Question 4 of 12 4. Turning of a radio set is an example of Musical resonance Mechanical resonance Electrical resonance Free vibrations Question 4 of 12Question 5 of 12 5. To make the frequency double of a spring oscillation, we have to: Quadruple the mass Half the massReduce the mass to one fourth Double the mass Question 5 of 12Question 6 of 12 6. The time period of the same pendulum at Karachi and Murree are related as: Tk>TM Tk2TK=3TMTk = TM Question 6 of 12Question 7 of 12 7. Two springs of spring constants k₁ and k₂ are joined in series. The effective spring constant of the combination is given by (k₁ + k₂)/2 √k₁k₂k₁ + k₂ k₁k₂/(k₁ + k₂) Question 7 of 12Question 8 of 12 8.
