A resistor of 10Ω10 \Omega10Ω and an inductor of 0.50.50.5 H are connected in series to a 20V20V20V DC source. Find the time constant of the circuit.

A simply supported beam of length 6 m carries a uniformly distributed load of 333 kN/m. Calculate the maximum bending moment in the beam.

Convert the decimal number 156156156 into its binary and hexadecimal equivalents.

A chemical reactor operates at a pressure of 5 atm and a temperature of 300 K. If the volume of the gas inside is 10 L, calculate the number of moles of gas present using the ideal gas law. (R=0.0821L⋅atmmol⋅K)\left( R = 0.0821 \frac{L \cdot atm}{mol \cdot K} \right)(R=0.0821mol⋅KL⋅atm).
