ANSWER:

In a spectroscopy experiment, electromagnetic radiation of a specified range of wavelengths is allowed to pass through a sample CONTAINING a COMPOUND of interest. The sample molecules absorb energy from some of the wavelengths, and as a RESULT jump from a low energy 'ground state' to some higher energy 'excited state'.

Answer:

Bernoulli’s theorem was INVENTED SWISS mathematician namely Daniel Bernoulli in the year 1738. This theorem states that when the SPEED of liquid flow increases, then the pressure in the liquid will be decreased based on the energy conservation law. After that, Bernoulli’s equation was derived in a NORMAL form by LEONHARD Euler in the year 1752. This article discusses an overview of what is a Bernoulli’s theorem, derivation, proof, and its applications.

QUESTION:

State Pascal's law for fluids with the help of a neat labelled diagram explain the principle and

working of hydraulic brakes.

ANSWER:

Pascal's principle of hydrostatics, or Pascal's law, states that the pressure exerted anywhere in a CONFINED incompressible liquid is equally transmitted throughout the fluid.

Explanation:

If a U-tube is filled with water and pistons are PLACED at each end, pressure exerted against the left piston will be transmitted throughout the liquid and against the bottom of the right piston. The pressure that the left piston exerts against the water will be exactly equal to the pressure the water exerts against the right piston. Suppose the tube on the right side is made wider and a piston of a larger area is used; for example, the piston on the right has 50 times the area of the piston on the left. If a 1 N load is placed on the left piston, an additional pressure due to the weight of the load is transmitted throughout the liquid and up against the larger piston. The DIFFERENCE between force and pressure is important: the additional pressure is exerted against the entire area of the larger piston. Since there is 50 times the area, 50 times as much force is exerted on the larger piston. Thus, the larger piston will support a 50 N load - fifty times the load on the smaller piston.

Forces can be multiplied using such a device. One newton input produces 50 newtons output. By further increasing the area of the larger piston, forces can be multiplied, in principle, by any amount. Pascal's principle underlies the operation of the hydraulic press. The hydraulic press does not violate energy conservation, because a decrease in distance moved compensates for the increase in force. When the small piston is moved downward 100 centimeters, the large piston will be raised only one-fiftieth of this, or 2 centimeters. The input force multiplied by the distance moved by the smaller piston is equal to the output force multiplied by the distance moved by the larger piston; this is one more example of a simple machine operating on the same principle as a mechanical lever.

A typical application of Pascal's principle for gases and liquids is the automobile lift seen in many service stations. Increased air pressure produced by an air compressor is transmitted through the air to the surface of oil in an underground reservoir. The oil, in turn, transmits the pressure to a piston, which lifts the automobile. The relatively low pressure that exerts the lifting force against the piston is about the same as the air pressure in automobile tires. Hydraulics is employed by modern devices ranging from very small to enormous. For example, there are hydraulic pistons in almost all construction machines where heavy loads are involved.

Answer:

The work done on a body moving in a circular PATH is also zero. This is because, when a body moves in a circular path, then the centripetal force acts along the RADIUS of the circle, and it is at right angles to the motion of the body. THUS, the work done in the case of MOON moving round the earth is also zero.

Answer:

Weetabix exports its breakfast cereals to more than 80 countries around the world, and each locality has characteristics distinct from the next.



How firms are using their global brands to spark cultural change in local markets: read the cover feature here

How does Burton’s Biscuits – a “small to medium-sized enterprise” that takes pride in its British roots – aim treble its overseas sales in five years? Chief commercial officer Steve Newiss talks about their strategy

Yes, Prime Minister: Britishness itself is “no help at all” in attracting an audience to a play, says Mark Goucher, producer of the stage ADAPTATION of political comedy

Launching MailOnline in the US – what did it take? James Bromley, managing director, explains all

In its highly competitive homeland of the UK, Weetabix’s share of overall cereal sales stands at around 7%. In contrast, it has 70% of the cereal sales in Kenya.

However, Kenya is a relatively undeveloped breakfast cereal market and Weetabix has forged ahead there partly because other manufacturers have not devoted SERIOUS thought to breaking in. The company has found a distribution strategy that suits the mode of consumption – a bicycle-borne sales force that delivers sachets containing two biscuits to small rural shops.

While Kenyans tend to opt for a small-value transaction, the complete opposite model is used by Weetabix to sell its cereal in Mexico. There, consumers are more likely to buy large boxes containing 48 biscuits.

Any brand must adapt to the unique conditions of a particular market. But even if the proposition changes, for Weetabix the core product generally remains the same.

According to chief EXECUTIVE Giles Turrell (pictured, above), opening up a new region for the first time OFTEN means teaching people about what a brand stands for and the BASIC cultural concept of how to consume it.

“In many markets, what we know as a breakfast cereal – in terms of a bowl with milk – is not as established as it is in the UK or the US. In some countries, we will be doing more of an educational job.

“The other thing about Weetabix is that the brand is not as developed internationally as it is in Britain. In the UK, we only have to say ‘Weetabix’ and most people know about it. They are familiar with the brand.”

Having secured £900m in new finance in 2011, Weetabix is currently on the path to international expansion. It is seeking low double-digit percentage growth abroad in 2012, focusing on a selection of markets “where we have a right to play, and perhaps a right to win”, Turrell says.

Though Weetabix has a portfolio of brands including Weetos, Ready Brek, Oatibix and a number of variations on the basic products, the company initially plans to use just two of them in its international push – Alpen and Weetabix.

But Turrell has ambitions to replicate the success in the UK across the world. “Of the more than 80 markets we export to, we have identified a handful that we really want to grow consistently with how we are growing Weetabix and Alpen in the UK,” he says.

But the messages are different from its UK marketing: “In the UK, our Fuel for a Big Day campaign is based on an insight. It is based on an emotional positioning and it’s talking about how it can help families through a busy day.”

In less developed markets, the message is more functional. “We will have to talk more about the benefits of what the brand does – whole grain, energy, low fat, low sugar, high fibre,” says Turrell.
