A generator is made from a set of 7000 loops of area 5.00 cm2rotating at an angular frequency of 600 radians per second. The magnetic field is created by a solenoid, completely surrounding the generator coil, and carrying a current of0.500 A. How many turns per unit length must the solenoid have in order for the generator to generate a peak emf of 1000 V?
The left end of a long glass rod 15.0 cm in diameter has a convex hemispherical surface 7.50 cm in radius, Determine the position of the image if an object is placed in air on the axis of the rod
A spherical conducting shell has 12 microcoulombs of positivecharge inside on it. The radii of the shell are r(inner)=12 cm and r (outer)=2r(inner). A particle of -4 microcoulombs is placed at the center of the shell.
Carry out the following arithmetic operations: (a) sum of the measured values 756, 37.2, 0.83 and 2.5. The answer must be in significant digits. Since 2.5 and 0.83 have two significant digits, shouldn't the answer be 800 instead of 797.
