Hi!

Option A is correct.

In cooking, convection is the phenomena that causes molecules with a higher energy at the bottom of a container to travel upwards, and the molecules at the top with a lower energy to sink to the bottom and replace them.

Mechanical convection describes this phenomena as a result of the application of an external force.

This phenomena is restricted to substances that are in liquid, or gaseous state, as molecules of a substance in solid state have a very restricted movement.

Hence, options B, C and D are incorrect.

Hope this helps!

Wewaii [24]

Answer: Indeterminate; Increases

Explanation:

We know that sensors are used as an input in the production of digital cameras. So, if the price of sensors falls, as a result cost of production of digital cameras also falls. This will increase the supply of cameras and shift the supply curve rightwards.

At the same time successful ad campaign will make the digital cameras more fashionable and increases the demand for digital cameras. This will also shift the demand curve rightwards.

Hence, there is an increase in the equilibrium quantity but effect on equilibrium price is indeterminate because it will be depend upon the magnitude of the shift of demand and supply curve.
