Parallel rays of light of intensity \(I\) = 912 Wm–2 are incident on a spherical black body kept in surroundings
of temperature 300 K. Take Stefan-Boltzmann constant \(\sigma\) = 5.7 \(\times\) 10–8 Wm–2K–4 and assume that the energy
exc...

A wire, which passes through the hole in a small bead, is bent in the form of quarter of a circle. The wire is fixed vertically on ground as shown in the below figure. The bead is released from near the top of the wire and it slides along t...

A block of mass m1 = 1 kg another mass m2 = 2 kg, are placed together (see figure) on an inclined plane with angle of inclination \(\theta\). Various values of \(\theta\) are given in List I. The coefficient of friction between the block m1...

When d \(\approx\) a but wires are not touching the loop, it is found that the net magnetic field on the axis of the loop is zero at a height h above the loop. In that case

Consider d >> a, and the loop is rotated about its diameter parallel to the wires by 30\(^\circ\) from the position shown in the below figure. If the currents in the wires are in the opposite directions, the torque on the loop at its new po...

A glass capillary tube is of the shape of truncated cone with an apex angle \(\alpha\) so that its two ends have cross sections of different radii. When dipped in water vertically, water rises in it to a height h, where the radius of its cr...

If the piston is pushed at a speed of 5 mm s\(-\)1, the air comes out of the nozzle with a speed of

If the density of air is \(\rho\)a and that of the liquid \(\rho\)l, then for a given piston speed the rate (volume per unit time) at which the liquid is sprayed will be proportional to

A person in a lift is holding a water jar, which has a small hole at the lower end of its side. When the lift is
at rest, the water jet coming out of the hole hits the floor of the lift at a distance d of 1.2 m from the person.
In the follo...

A tennis ball is dropped on a horizontal smooth surface. It bounces back to its original position after hitting the surface. The force on the ball during the collision is proportional to the length of compression of the ball. Which one of t...
