At resonance, the reactances of the inductor and the capacitor cancel each other so that the impedance (z) is equal to just the resistance (r). calculate the resistance of the circuit by using the amplitude of the current at resonance in the equation r=v/i (where v is the amplitude of the applied voltage). is this resistance equal to 10 ohms? why not?

Two polarizers are oriented at 40∘ to each other and plane-polarized light is incident on them. if only 16 percent of the light gets through both of them, what was the initial polarization direction of the incident light?

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the
