A circular coil of wire 8.40cm in diameter has 16.0 turns and carries a current of 2.60A . The coil is in a region where the magnetic field is 0.580 T
Part A What orientation of the coil gives the maximum torque on the coil ?
Part B What is this maximum torque in part (A)?
Part C For what orientation of the coil is the magnitude of the torque 71.0% of the maximum found in part (B)?
A total of 34 bright and 34 dark Newton's rings (not counting the dark spot at the center) are observed as 550 -nm light falls normally on a planoconvex lens resting on a flat glass surface. How much broad is the center than the edges.
A sound wave travels in air toward the surface of a freshwater lake and enters into the water. The frequency of the sound does npt change when the sound enters the water. The wavelength of the sound is 2.49 m in the air, and the temperature of bot..
You're driving down the highway late one night at 20 m/s while a deer steps onto the road 44m in front of you. Your reaction time before stepping on the brakes is 0.50 s, and the maximum deceleration of your car is 11m/s^2 .How much distance is be..
A. The rate of hydrogen fusion (proton-proton chain) near 10^7 K increases with temperature as T^5. If you raise the temperature of the hydrogen-burning core by 10 percent, how much does the hydrogen fusion energy increase?
Calculate the period of a ball tied to a string of length 0.3 m making 6.9 revolutions every second. Answer in units of s, Calculate the speed of the ball
The equation of a transverse wave traveling on a string is given by y = A sin(kx - ?t) . Data: A=11 mm, k=73 rad/m, ?= 280 rad/s. What is the amplitude? What is the frequency? What is the wave velocity? What is the wavelength? For the same wave, f..
