There is no radioactive source in or near the chamber, and the room where this video was taken has very low radon levels and very low levels of radioactive materials in the building -- most of the tracks seen are from cosmic rays. This video was recorded in Colorado; how would the video differ if it had been recorded in Boston or another sea level location

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?

An uplifted block of rock between two normal faults
