For a uniform cube, find I about one edge.

Vector A = (8, 4, -5) and Vector B = (-2, 3, 0). Find the angle between these two vectors.

If possible give the final answer with 4 decimal places

Please solve 34 and 35.

The vector product of vectors A and B has magnitude 20.0 m² and is in the+z-direction. Vector A has magnitude 8.0 m and is in the -z-direction. Vector B has no z-component What is the direction angle 0 of vector B measured from the +y-direction to the +z-direction?

The x and y coordinates of point P are (-8.50 m, -7.00 m). What is the polar angle of point P?

Two blocks are released from rest on either side of a frictionless half-pipe (see the Figure below). Block B is less massive than block A. The height HB from which block B is released is less than HA, the height from which block A is released. The blocks collide elastically on the flat section. HA B HB 1) After the collision, which is correct? Block A rises to a height greater than HA and block B rises to a height less than HB. Block A rises to a height less than HA and block B rises to a height greater than HB. Block A rises to height HA and block B rises to height HB. Block A rises to height HB and block B rises to height HA. The heights to which the blocks rise depends on where along the flat section they collide. Submit

Scalars and vectors:  Vector A has a magnitude of 9.0 and Vector B has a magnitude of 3.0. If the vectors are at an angle of 30.0º, what is the magnitude of the cross product A x B?                                                      Here are the choices:     13.5   16.2   23.4   27.0

The vector -5.2 A→ has a magnitude of 37 mm and points in the positive x direction. Find the x component of the vector A→?

Vector A has a magnitude of 4 m and lies in the xy plane directed at 45 degrees counterclockwise from the positive x axis, whereas the vector B has a magnitude of 3m and lies in the yz plane directed at 30 degrees from the positive z axic. Find the cross product A x B and the angle between the vectors.
