1. Two very large (50m x 50m) and 10mm thick plastic discs have the volume charge density ρ1 = +5μC/m3 for the left disc and ρ2 = +3μC/m3 for the right disc in the figure. The discs are placed in parallel. The adjacent surfaces of the discs are 5mm apart. Use Gauss law and superposition to determine the size and direction of the electric field at the following points, far from the outer edges of these discs.

a) Dot A, 5mm from the left side of the left disc
b) Dot B, 2mm from the left side of the right disc
c) Point C, in the middle of the right disc.

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?

Aplanet of mass m 6.75 x 1024 kg is orbiting in a circular path a star of mass m 2.75 x 1029 kg. the radius of the orbit is r 8.05 x107 km. what is the orbital period (in earth days) of the planet tplanet?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
