Two alpha particles (helium nuclei), each consisting of two protons and two neutrons, What is the distance between these particles at this time
An emf is induced in a conductin loop of wire 1.03 m long as its shape is changed from square to circular. Find the average magnitude of the induced emf if change in shape occurs in 4.15s and the local 0.131-T magnetic field is vertical to the pla..

A motorboat heads due east at 11.00 m/s across a river that flows toward the south at a speed of 3.40 m/s. What is the resultant velocity relative to an observer on the shore? If the river is 1360m wide, how long does take the boat to cross.
After being accelerated to a speed of 1.26×105 m/s, the particle enters a uniform magnetic field of strength 2.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen). The results of this experiment allow one..
