AIEEE 2005 Physics Question Paper Mock Test

If a simple harmonic motion is represented by $\frac{d^{2}x}{d{t}^2}+\alpha x=0$, its time period is:

The bob of a simple pendulum is a spherical hollow ball filled with water. A plugged hole near the bottom of the oscillation bob gets suddenly unplugged. During observation, till water is coming out, the time period of oscillation would:

An observer moves towards a stationary source of sound, with a velocity one fifth of the velocity of sound. What is the percentage increase in the apparent frequency?

If $I_0$ is the intensity of the principal maximum in the single slit diffraction pattern, then what will be its intensity when the slit width is doubled?

Two concentric coils each of radius equal to $2\pi \text{ cm}$ are placed at right angles to each other. $3\text{ Ampere}$ and $4\text{ ampere}$ are the currents flowing in each coil respectively. The magnetic induction in Weber/m${}^2$ at the centre of the coils will be (${\mu }_0=4\pi \times 10^{-7}$ W/A-m):
