Two vehicles collide and stick together. After the collision, their combined y-momentum is 2.40 × 104 kilogram meters/second, and their x-momentum is 7.00 × 104 kilogram meters/second. What is the angle of the motion of the two vehicles, with respect to the x-axis?

Explanation:

It is given that,

Momentum in y direction is

Momentum in x direction is

We need to find the angle of the motion of the two vehicles, with respect to the x-axis. The angle between two vectors is given by :

So, the angle of the motion of the two vehicles is 18.88 degrees.

empty space could also be a simple vacuum

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
