At some instant an alpha atom (q=+2e) has the coordinates (3.0,0.0,0.0)(nm) and is moving along the positive x axis with 500 km/s while an electron at (0.0,4.0,0.0)(nm) is moving along the y axis with 1000 km/s.
a) Find the magnitude and direction of the total magnetic field at the origin.
b) Find the magnitude and direction of the magnetic force felt by the electron.
A cylindrical container with a cross-sectional area of 67.2 cm2 holds a fluid of density 756 kg/m3. Calculate what is the depth of the fluid
When a parachute opens, the air exerts a large drag force on it.This upward force is initially greater than the weight of the skydiver and, thus, slows him down. Suppose the weight of the skydiver is 902 N and the drag force has amagnitude of 1030..

A woman throws a ball at a vertical wall d = 3.0 m away. The ball is h = 1.5 m above ground when it leaves the woman's hand with an initial velocity of 12 m/s at 45°.
A concave mirror forms a real image twice as large as the object. The object is then moved such that the new real image produced is three times the size of the object. If the image was moved 62.5 cm from its initial position, how far was the objec..
