The permeability of free space is 1.25664 x 10^-6 T m/a. Compute the magnetic field strength that this motion produces at the location of the proton.
The transmission line resistance is 0.30Ω/cable and the power of the generator is 250kW. If Vt = 80kV, what are the (a) voltage decrease ?V along the transmission line.
In an 8.00 km race, one runner runs at a steady 11.0 km/h and another runs at 14.3km/hr. How far from the finish line is the slower runner when the faster runner finishes the race?
A 35.0-g bullet moving at 475 m/s strikes a 3.2-kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 225 m/s. How fast is the bag moving when the bullet exits?
Black Holes are suspected when a visible star is being noticeably pulled by an invisible partner that is more than 3 times as massive as the Sun. A red giant star is accelerated in a linear direction by gravity at 0.075 m/s2 towards an object that
