The Moon has a lower gravitaional field strength than the Earth, and it does not have an atmosphere. The lower gravitational field strength means that there is lower acceleration, which results in an incr...

When ice (or ice cold water) is added to a drink, the two substances move towards thermal equilibrium (the point where there is no net energy transfer between the two substances, and they have the same te...

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...
