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.

Answer: b. The United States Constitution
Explanation:
Montesquieu argued that the best form of government, was one where the legislative arm, executive arm, and judicial powers were separate. and in doing so helped kept each other in check to prevent any branch from becoming too powerful. Montesquieu’s separation of powers was not accurate when compared the government of England, But this was later adopted by Americans as the foundation of the U.S. Constitution.
<u>Answer</u>
D. Base units
<u>Explanation</u>
Basic units are also called fundamental units. They are the standard units agreed internationally for measurements. Most of these measurements are taken from the ground and they are used to derive other units. They are seven in number. There are:
The metre (m)
The kilogram (kg)
The second (s)
The ampere (A)
The kelvin (K)
The candela (cd)
The mole (mol)
Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. ... As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
