Q:

Which of the following is not an intensive property?

A) Weight B) Density
C) Refractive index D) Melting point
 
Answer & Explanation Answer: A) Weight

Explanation:

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system, if the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged. Additionally, the boiling point of a substance is another example of an intensive property. For example, the boiling point for water is 100 °C at a pressure of one atmosphere, a fact which remains true regardless of quantity.

A) light rain over a large area B) a decrease in stream discharge
C) rapid spring snowmelt D) increased capacity of stream channels
 
Answer & Explanation Answer: C) rapid spring snowmelt

Explanation:

There are lots of reasons behind the flood in any area but the main reason is a heavy downpour or rapid snowmelt can flood canyons with a mixture of soil, rock, and water is a major cause of floods.

 

When the spring times come, sometimes there's a lot of warmth that suddenly comes, especially nowadays when there are things such as global warming. So the snow melts and large amounts of water can flood the fields that are often found at the foot of a mountain or similar things.

 

But they may also be caused by deforestation, drainage channel modification from a landslide, earthquake or volcanic eruption. Examples include outburst floods and lahars.

Q:

Managing direct and online marketing :

What is direct marketing? Give some examples.

Answer

In direct marketing, there is a direct interaction of the customers with the seller without any intermediaries. Here, the role of the intermediaries is nil. The medium used is more direct using telephone, mail, internet where the seller can directly reach out to the consumer. Examples of such marketing include telemarketing, email, voicemail marketing, door-to-door selling etc. This kind of marketing is more time saving as the problem of distance which may otherwise exist between the buyer and seller is eliminated and is also cost effective as it minimizes commuting costs.
