3. Stored value card based payment systems (pay before)

In February 1950, Frank McNamara and Ralph Schneider created The Diners Club card which was made of paper-cardboard. Initially The card was accepted in only 27 restaurants From 1955, the card was made of plastic. The Diners Club still exists today under the name Diners Club International.

(d) Multiple bank accounts cannot have single VPA

Many cryptocurrencies operate on the basis of the same source code, in which the authors make only a few minor changes in parameters like time, date, distribution of blocks, number of coins, etc. These currencies are called as fork. In fork, both cryptocurrencies can share a common transaction history in block chain until the split.

Advantages of credit card:

1. Most credit cards are accepted worldwide.

2. It is not necessary to pay physical money at the time of purchase. The customer gets an extra period to pay the purchase.

3. Depending on the card, there is no need to pay annuity.

Copper plate(+), Iron spoon(-), Copper sulphate electrolyte is the correct setup combination for electroplating. Because the anode is made the metal to be deposited and cathode to the one on which it is electroplated.

The word insolation means ‘sol’, i.e. Sun and ‘in – ation’, which means coming in. On this basis, solar radiation received from the Sun by the Earth is called insolation. So solar radiation coming on the surface of earth is called insolation. The entire insolation does not reach the Earth’s surface, and only a fraction of it (two billionth part) reaches the earth.

The amount of insolation in a certain area varies according to weather and atmospheric conditions. 

The amount of temperature obtained from the Sun on the surface is influenced by the following factors:

1. Distance from the equator: Sun rays are usually incident vertical at the equator, whereas, when we proceed towards the north and south direction, away from the equator, the rays are incident at a slanting angle, which has an effect on the insolation. 

2. Height above sea level: As the height increases, the temperature decreases. 

3. Distance from the sea level: In the regions near the ocean, the temperature is less, whereas in the inland parts, the temperature increases. 

4. Sea currents: According to the cold and hot water currents of the oceans, the temperature continues to be low or high. 

5. Prevailing winds: Winds increase or decrease the temperature according to their cold and warm nature. 

6. Slope of land: According to the front and opposite slope of land form facing towards or away from the sun there is variation in temperature. 

7. Nature of the Surface: Whether a region is forested or not or is glaciated or not has an impact on temperature. 

8. Clouds and rainfall: The position of clouds also acts as temperature controller.

The expansive area of Siaberia is situated in the Northern part of Eurasia. Here continental type of climate is found. The temperature increases due to the Gulf stream water stream in the oceanic areas and the North Atlantic drift. These currents have very little effect in the inner part of the continent. Therefore, the temperature remains low in the inner part.

In winter, the temperature in most part of the ground falls even below 0°C. The lowest temperature of the world is recorded in this part. Thus, due to the effects of water bodies in the coastal areas and their wide surface area, the high latitudes and impact of the wind forms and the continental climate, the temperature range is found to be highest there.

In January, the sun’s rays are vertical on the Tropic of Capricorn in the Southern Hemisphere.

Correct Answer is: (d) 8 minutes

The angle of dip of sunrays plays an important role in influencing the quantity of insolation. The direct rays of the sun provide more insolation than the slant rays. 

This is because of the following two reasons:

1. The direct rays have to cross the narrower layer of the atmosphere, therefore less energy is destroyed in the atmosphere. While skewed rays cross the broader part of the atmosphere, so more energy is destroyed in the atmosphere.

2. The direct rays heat lesser part of the surface while the same amount of slant rays warm a greater area of the surface. Therefore, direct rays provide more insolation than slant rays.
