Answer:
Magnetic field must be in YZ plane except in negative and positive Z direction.
Explanation:
Here loop is in XY plane and current direction as defined then its magnetic moment is in negative Z direction.
- So to rotate loop about X axis force should be in plane YZ.
- Thus torque produced by this magnetic force is in direction of X axis.
Now we know torque on a loop is calculated by
Torque=magnetic moment × B (vector cross product)(Here B is magnetic field)
Thus magnetic field can be in the positive and negative Y direction and Z direction.

Components connected in series are connected along a single path, so the same current flows through all of the components. If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is across each bulb and they all glow.
Answer:
2.Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
Explanation:
1. I do not understand what is being asked.
If you could comment with more understandable question ill do my best to help. (:
I think it is the last choice because light can travel as waves but it can also travel through a vacuum in an airless space.
I think the answer is d. The circulatory system carries chemical signals from your endocrine system that control the speed of digestion.
