As part of your summer job asa design engineer-assistant at a NASA contractor, your team has been assigned to design a powersystem for orbiting satellites. Your team hasdevised an orbiting “drop cable” system that creates an induced EMF by moving a cable througha magnetic field. In a test, your team dropsa 30.0 km-long cable from the space shuttle,orbiting at a speed of 8.00 x 103 m/s. The magnitude of theearth’s magnetic field at the shuttle’s location isabout 6.50 x 10-5 T.a) Find the motional EMFinduced between the ends of the cable. Assume, and state, what the angle should be between the cableand the magnetic field to get the largestEMF. b) If you were to use this EMF (voltage)to operate electrical devices on the satellite, you would have to connect the far end of the wire to thesatellite. Can you think how to do this? Drawa diagram and show how current would flow.
A satellite is placed in orbit 7.2 x 105 mabove the surface of Jupiter. Jupiter has a mass of 1.90 1027 kgand a radius of 7.14 x 107 m. Find the orbital speed of the satellite
q1. if work function 1.85 ev wavelength 410 nm what is stopping potential and maximum speed of photoelectrons emitted
to move a large crate across a rough floor you push on it with a force f at an angle of 21deg below the horizontal.
Light of wavelength 650 nm is incident above at an angle of 90 upon a glass plate as shown below. The glass plate rests on top of a second plate so that they touch at one end and are seperated by .0325mm at the other end as shown in the figure.
A ray of sunshine is passing from diamond into crown glass; the angle of incidence is 35.00 degrees. Determine the angle between the refracted blue and red rays
Two 40.0 µF capacitors in parallel are connected across a sinusoidal ac generator operating at 60.0 Hz. how much current passes through each capacitor
A projectile is shot from the edge of a cliff h = 305 m above ground level with an initial speed of v0 = 155 m/s at an angle of 37.0° with the horizontal. Find the maximum height above the cliff top reached by the projectile
A 0.75m diameter solid sphere may be rotated about an axis through its center by a torque of 11.5m*N which accelerates it uniformly from rest through a total of 180 revolutions in 16.0 s.What is the mass of the sphere.
three uniform thin rods, each of length L = 39 cm, form an inverted U. The vertical rods each have a mass of 15 g; the horizontal rod has a mass of 32 g. Elucidate what are (a) the x coordinate and (b) the y coordinate of the system's center of ma..
