The orbit of a particle moving under the influence of a central force is r0 c. the quantity c is a constant (a) determine the potential energy as a function of r. (b) calculate the angular momentum in terms of c and the total energy e.

In an experiment, how can i change human errors? be specific.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
