Answer:
D. 9 N
Explanation:
The tension on the string is equivalent to the centripetal force.
Centripetal force is the force exerted by an object in circular motion or path towards the center of the circular path.
Centripetal force = mv²/r
where m is the mass of the object, v is the velocity and r is the radius of the circular path.
Centripetal force = (0.25 kg × 6²)/ 1
= 9 N
Thus, the tension on the string is 9 N
Answer:
microwave, visible light, and radio waves.
Explanation:
Answer:
toward the ceiling
Explanation:
In order to determine the direction of the magnetic force on the charge, we should use the right-hand rule. Putting the thumb, the index finger and the middle finger of the right hand perpendicular to each other, we have: (for a positive charge)
- The index finger corresponds to the direction of motion of the charge (in this case, toward north)
- The middle finger corresponds to the direction of the magnetic field (in this case, towards west)
- The thumb will give us the direction of the magnetic force --> in this case, the thumb points towards the ceiling, so the direction of the magnetic force is towards the ceiling.
