Answer:

THE COEFFICIENT OF LINEAR thermal expansion (CTE, a, or a1) is a material property that is indicative of the extent to which a material expands upon heating. Different substances expand by different amounts. Over small temperature ranges, the thermal expansion of uniform linear objects is proportional to temperature change. Thermal expansion finds useful application in bimetallic strips for the construction of thermometers but can generate detrimental internal stress when a structural part is heated and kept at constant length.

Answer:

A presentation is a form of oral communication in which a person shares factaul information with an audience that is generally.

Answer:

Stereotyping refers to an oversimplified idea of the typical characteristics of a person or thing. Generalization is making a general statement to encompass all individuals who belong to a particular category.

Answer:

A) Downwards.

B) Because BC is in the same direction as the direction of field line. Force is minimum when the direction of current in the conductor is the same as that of the magnetic field. BC will not contribute as the force on this part of the coil will be cancelled by the force on DA.

Explanation:

a) When battery is switched on, the current flows through the coil ab from a to b and magnetic field is north to south. So, by Fleming's left hand rule, downward force is applied on ab.

b) Because current in arm bc travels in the same direction as the magnetic field lines. When the direction of the magnetic field and current are parallel. The resultant force on the current carrying conducter will be zero. Hence, current in arm bc does not countribute to the movement of coil.
