A potential difference of 18 V is applied to a resistor whose resistance is 240 Ω . What is the current that flows through the resistor?

Which form of pure carbon is so hard that it can be used in cutting tools?

Why does it dangerous to jump from a moving vehicle?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 50 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/k.
