Answer:
Friction works against the motion and acts in the opposite direction. When one object is sliding on another it starts to slow down due to friction. ... By rubbing them together we generate friction and, therefore, heat. The force F of friction pushes back on the block
Explanation:
Answer: The force is directed upward
Explanation: Considering the Lorentz force, given by:
F= qv×B
using the right hand rule and considering the direction of electron velocity and the magnetic field from the figure, the vectorial product gives a force vector upwards .
Answer:
Option B is the right answer.
Crafting, reusing
Good luck!
