The key equation is that of the energy of a photon.
E = hc/λ
Using λ = 550nm gives E = 3.61x10^-19...
To solve this problem, we must apply conservation of momentum. Even though there is kinetic energy being added to the probe-capsule system by the explosion, momentum will always be conserved if there a...
Let us consider a simple dc circuit consisting of a battery and a resistor connected by ideal wires. As we know, current starts to flow thorugh the resistor and heat is generated as a result of this cu...
No; this is a common misconception! Batteries store energy, which is used to push electrons (charges) around a circuit. The flow of electrons is called current. As the electrons flow through the circui...
