The diffraction pattern of a crystalline solid gave a peak at \( 2\theta = 60^\circ \). What is the distance (in cm) between the layers that gave this peak? \[ \text{(Given: Wavelength } \lambda = 1.544\text{ Å, } \sin 30^\circ = 0.5, \sin 60^\circ = 0.866, n=1) \]
A projectile is projected with velocity of \( 40 \) m/s at an angle \( \theta \) with the horizontal. If \( R \) is the horizontal range covered by the projectile and after \( t \) seconds its inclination with horizontal becomes zero, then the value of \( \cot \theta \) is:
[Take, \( g = 10 \) m/s\( ^2 \)]

A hydrocarbon containing C and H has 92.3% C. When 39 g of hydrocarbon was completely burnt in O2, x moles of water and y moles of CO2 were formed. x moles of water is sufficient to liberate 0.75 moles of H2 with Na metal. What is the weight (in g) of oxygen consumed?

RMS velocity of one mole of an ideal gas was measured at different temperatures. A graph of \( (u_{\text{rms}})^2 \) (on y-axis) and \( T/K \) (on x-axis) gave a straight line passing through the origin, and its slope is \( 249 \, \text{m}^2 \text{s}^{-2}\text{K}^{-1} \). What is the molar mass (in kg mol\(^{-1}\)) of the ideal gas? \(( R = 8.3 \, \text{J mol}^{-1} \text{K}^{-1} )\)
