Astar of mass 3 × 1030 kg is located at < 6 × 1012, 2 × 1012, 0> m. a planet of mass 6 × 1024 kg is located at < 4 × 1012, 4 × 1012, 0> m and is moving with a velocity of < 0.6 × 104, 1.1 × 104, 0> m/s. (a) during a time interval of 1 × 106 seconds, what is the change in the planet's velocity?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

1. how to locate the image in converging(concave) mirror and diverging (convex) mirror with salt. 2. how to locate the image in a converging (convex) lens and diverging (concave) lens with salt.

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
