An electron ( -1.6*10e-19 c ) experience a force F of (3.2i -2.27j)10e-13N when passing through a magnetic field B of (o.72kT). What is the velocity of the electron?  note the k is a vector.

The world’s largest cut diamond is the First Star of Africa. Its volume is 30.2 cubic centimeters.What is its volume in cubic inches? In cubic feet?

What is magnetic flux density?

Using the minimum travel time and the straight-line distance, determine the magnitude (size) only of the average velocity for the trip. DO NOT worry about the direction.

Straight-line Distance: 378.43km

Time: 1 hour, 11 minutes, 50 seconds

Using the driving distance from your home to Point B, what would your average speed be if the trip takes you exactly 4.50h? 

Driving Distance: 489 km

In simple harmonic motion, when is the speed the greatest?
I. when the magnitude of the force is minimum
II. when the potential energy is maximum.
III. when the potential energy is zero.
IV. when the displacement is maximum.
