10th Class Physics MCQS
The time period of simple pendulum can be calculated by:
T = 2 ? ?g/L
T = 2??L/g
T = 2 ? ?m/k
T = 2 ? ?K/m
The distance between two consecutive troughs or crests is called:
Frequency
wavelength
None of these
Time period
In there is no extension in the spring then this positon is called
Nautral equilibrium
Stable equilibrium
Equilibrium position
Unequilibrium
A large ripple tank with a vibrator working at a frequency of 30 Hz produces 25 complete waves in a distance of 50 cm.The velocity of the wave is:
60 cms-1
53 cms 1
1500cms 1
750 cms 1

If the mass of the bob of a pendulum is increased by a factor of 3. The period of the pendulum’s motion will:
Be increased by a factor 2
Be decresaed by a facro of 4
Be decreased by a factor of 2
Remain the same
The wave properties
All of these
Diffraction
Reflection
Refraction
Which of the following characteristics of a wave is independent of the others:
speed
wavelength
frequency
amplitude
Typographical errors in BASIC statements are:
Execution errros
Syntax errors
Logical Errors
Runtime errors
If the mass of a spring mass system is doubled, its time period becomes:
