Q1. What is the minimum distance between two point that will permit them to be resolved at 1,00km using a terrestrial telescope with a 6.5cm diameter objective? Take λ=550nm.
Q2. A cube of ice is taken from the freezer at -8.0°C and placed in a 97 g aluminium calorimeter filled with 286 g of water at room temperature of 20°C. The final situation is observed to be all water at 19°C. What was the mass of the ice cube?
Q3. A vertical, infinite, non conducting plane has uniform positive charge. A weightless thread is attached to the plane, and at the end of thread there is a small spherical ball with a charge of +78.6 μC, and a mass of 0.954 kg. The angle that the thread makes with a plane is 37.3°. What is the charge density σ of the plane?
