The speed versus time graph for a particle is shown in the figure. The distance travelled (in m) by the particle during the time interval t = 0 to t = 5 s will be __________

The change in the magnitude of the volume of an ideal gas when a small additional pressure $$\Delta P$$ is applied at a constant temperature, is the same as the change when the temperature is reduced by a small quantity $$\Delta T$$ at constant pressure. The initial temperature and pressure of the gas were 300 K and 2 atm respectively. If $$|\Delta T| = C|\Delta P|$$ then value of C in (K/atm) is __________

Four resistances 40 $$\Omega$$, 60 $$\Omega$$, 90 $$\Omega$$, 110 $$\Omega$$ and make the arms of a quadrilateral ABCD. Across AC is a battery of emf 40 V and internal resistance negligible. The potential difference across BD in V is __________

The distance between an object and a screen is 100 cm. A lens can produce real image of the object on the screen for two different positions between the screen and the object. The distance between these two positions is 40 cm. If the power of the lens is close to $$\left(\frac{N}{100}\right)$$D where N is an integer, the value of N is __________
