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...
We know the formula for kinetic energy is
KE = (1/2)mv2.
If we know that c, the speed of light, is 3x108ms-1 (you will be given this value i...
