A ball is projected with a velocity, of 10 ms^-1 , at an angle of 60° with the vertical direction. Its speed at the highest point of its trajectory will be? NEET 2022
Please note that the angle given in the question is with vertical while in general the formula is derived for angle with horizontal.
A big circular coil of 1000 turns and average radius 10 m is rotating about its horizontal diameter at 2 rad s^-1 .If the vertical component of earth's magnetic field at that place is 2 × 10^-5 T and electrical resistance of the coil is 12.56 then the maximum induced current in the coil will be ? NEET 2022
Two transparent media A and B are separated by a plane boundary. The speed of light in those media are 1.5 × 10^8 m/s and 2.0 × 10^8 m/s, respectively. The critical angle for a ray of light for these two media is? NEET 2022
The area of a rectangular field (in m^2 ) of length 55.3m and breadth 25 m after rounding off the value for correct significant digits is ? NEET 2022
From Ampere's circuital law for a long straight wire of circular cross-section carrying a steady current, Explain the variation of magnetic field in the inside and outside region of the wire.
A nucleus of mass number 189 splits into two nuclei having mass numbers 125 and 64. The ratio of the radius of two daughter nuclei respectively is? NEET 2022
The volume occupied by the molecules contained in 4.5 kg water at STP, if the molecular forces vanish away, is ? NEET 2022
Molecular forces vanishes away meaning concept of gases is to be utilized.
Draw the graph when a spherical ball is dropped in a long column of a highly viscous liquid, which represents the speed of the ball (v) as a function of time (t).
Due to gravity tendency of a falling ball is of increasing velocity but due to viscous force (dragging) and thrust it faces upward force, out of these two the drag increases as velocity increases so after some time gravity is countered by thrust and drag.(upward) so no further increment in velocity.
Two pendulums of length 121 cm and 100 cm start vibrating in phase. At some instant, the two are at their mean position in the same phase. The minimum number of vibrations of the shorter pendulum after which the two are again in phase at the mean position is ? NEET 2022
Shorter pendulum faster oscillations.
Draw the graph which shows the variation of de Broglie wavelength (λ) of a particle and its associated momentum (p).
