Dual Nature of Radiation and Matter — Physics STD 12 Science — Question

A nut becomes loose and gets detached from a satellite revolving around the earth. Will it land on the earth? If yes, where will it land? If no, how can an astronaut make it land on the earth?

A 100pF capacitor is charged to a potential difference of 24V. It is connected to an uncharged capacitor of capacitance 20pF. What will be the new potential difference across the 100pF capacitor?

Define the SI unit of the magnetic field.

Find the loss in the mass of 1 mole of an ideal monatomic gas kept in a rigid container as it cools down by 10^°C. The gas constant R = 8.3 J/mol-K.

Consider a circuit containing an ideal battery connected to a resistor. Do "work done by the battery" and "the thermal energy developed" represent two names of the same physical quantity?

The total energy of electron is negative. What do you mean by this fact? It is positive then what is the indication?

The electric field intensity and electric potential at a point due to a point charge are 30 Newton/ Coulomb and 15 Joule/Coulomb respectively. Find (i) the distance of the charge from the observation point and (ii) the magnitude of the charge.

Which rules are followed in nuclear reactions?

In a Van de Graaff type generator a spherical metal shell is to be a 15 × 10⁶V electrode. The dielectric strength of the gas surrounding the electrode is 5 × 10⁷Vm^–1. What is the minimum radius of the spherical shell required? (You will learn from this exercise why one cannot build an electrostatic generator using a very small shell which requires a small charge to acquire a high potential.)
