The car's final velocity is 11.6 m/s in the opposite direction.
Answer:
Downwards into the plane
Explanation:
Solution:-
- This is a conceptual application of hand rule. We will place our palm fingers open vertical to a plane surface. Then curl our fingers in and naturally point the thumb.
- The direction of curl of fingers denotes the direction of of current flow in the coil. Which in our case is "clockwise direction". We will orient/invert our right hand palm in such a way that we curl our fingers in clockwise fashion. Then stick the thumb out to give us the direction of magnetic field or North pole end. In our case the the thumb points downwards into the plane denoting that the magnetic field within the loop is also acting downwards into the plane.
- The bar magnet would be placed in such a way that North pole is pointing downward into the plane in the direction of magnetic field and end up at south pole pointing up out of the plane.
Answer:
Option A
Air resistance
Explanation:
Despite the law of conservation of energy stating that energy can neither be created nor destroyed but can only be transformed from one state to the other, the process of transformation is not 100% efficient since some energy losses occur due to friction and air resistance. Therefore, when the final energy is slightly less than the original dor this case, it's due to energy loss due to air resistance.
We just keep meeting huh? I believe the wave to be longitudinal, because the energy is going left to right.
Answer:
7200N
Explanation:
Centripetal force is directly proportional to the product of the mass and the square of the velocity and inversely proportional to the radius given.
