• Bulb power = 6.0W - Energy provided = 480J - Use equation P = E / t (Power = energy/time) where power is in watts, energy is in joules, and time is in seconds - Rearrange the equation to give t = E ...

Well we know that the power of the bulb is given by P = IV. Therefore the power = (20 x 10^-3 Coulomb per second) * (5 Joules per Coulomb) = 100 x 10^-3 Joules per second = 0.1 W.

Find the verticle velocity by resolving the velocity vector:

Trigonometry: 50sin30 = 25m/s in upwards direction

Using SUVAT for the vertical direction: S=-10, U=25, A=-9.81, V=N/A, T=?:

The key to solving this is remembering that momentum is conserved. The large, initial particle has no speed so its momentum is zero. Therefore, if we add together the momenta of the final particles we als...

Newton's Third Law looks at what happens when two objects interact with each other. The definition of Newton's Third Law is, "When one body exerts a force on a second body, the second body simultaneo...
