Solve the following problem:
Problem: What accelerating voltage would be required for the electrons of an electron microscope if the microscope is to have the same resolving power as could be obtained using 121 keV gamma rays?
I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
A scalloped hammerhead shark swims at a steady speed of 1.8 m/s with its 80 cm wide head perpendicular to the earth's 56 µT magnetic field. Obtain the magnitude of the emf induced between the two sides
The speed of sound in air is 332 m/s at 0°C. It increased 0.60 m/s for each degree above zero. compute the speed of sound at the temperature of the room.
