A radioactive element $^{242}_{92}X$ emits two $\alpha$ particles, one electron and two positrons. The product nucleus is represented by $^{234}_P Y$. The value of P is
The fundamental frequency of sonometer wire is 'n'. If the tension and length are increased 3 times and diameter is increased twice, the new frequency will be
A body when projected at an angle \( \theta \) with the horizontal reaches a maximum height \( H \). The time of flight of the body will be ( \( g \) = acceleration due to gravity)
The fundamental frequency of a closed pipe of length \(L\) is equal to the second overtone of a pipe open at both the ends of length (XL). The value of X is (Neglect end correction)
The instantaneous value of current in an a.c. circuit is \(I = 3 \sin (50\pi t + \frac{\pi}{4})\text{A}\). The current will be maximum for the first time at
When source of sound moves towards a stationary observer, the apparent frequency heard by him
Two polaroids are placed in the path of unpolarised beam of intensity ' $\text{I}_0$ ' such that no light is emitted from the second polaroid. If a third polaroid whose polarisation axis makes an angle ' $\theta$ ' with the polarisation axis of first polaroid is placed between these polaroids then the intensity of light emerging from the last polaroid will be}
Two bodies A and B at temperatures ' $\text{T}_1$ ' $\text{K}$ and ' $\text{T}_2$ ' $\text{K}$ respectively have the same dimensions. Their emissivities are in the ratio $16 : 1$. At $\text{T}_1 = x\text{T}_2$, they radiate the same amount of heat per unit area per unit time. The value of $x$ is
At any time \( t \), the co-ordinates of moving particle are \( x = at^2 \) and \( y = bt^2 \). The speed of the particle is
What is the frequency of a wave with a wavelength of \( 2 \, \text{m} \) and a velocity of \( 4 \, \text{m/s} \)?
In a Young's double-slit experiment, the distance between the slits is \( 0.2 \, \text{mm} \) and the distance between the screen and the slits is \( 2 \, \text{m} \). If the wavelength of the light used is \( 600 \, \text{nm} \), calculate the distance between the two adjacent bright fringes.
A light ray passes from air (refractive index \( n_1 = 1 \)) into water (refractive index \( n_2 = 1.33 \)). If the angle of incidence is \( 30^\circ \), what is the angle of refraction in the water?
In biprism experiment the maximum intensity is ' \(I_0\) '. If the path difference between the two interfering waves is ' \(\lambda/4\) ' then intensity at the point on the screen is \(\left[ \sin 45^\circ = \cos 45^\circ = \frac{1}{\sqrt{2}} \right]\)
