Thus, Since the turn of the 20th century, glass has been made with calcium fluoride, a novel substance. It is a solid that dissolves readily in water and has a special physical and chemical makeup that makes it suitable for usage as a glassmaking material.
Glass used in windows, bottles, and other glass goods was formerly created from calcium silicates before the invention of this substance. The new glass, referred to as glass with added fluorides, has a number of advantages over calcium silicates, which have drawbacks that make them unsuitable for the creation of modern glass.
Calcium Fluorine is a naturally occurring element that is frequently found in rock, soil, plants, and animals.

Why is it possible for railway tracks to buckle even though there are gaps in them?
These gaps which are of the order of a few millimeters, are provided to allow room for the rails to expand the rise in temperature due to the atmospheric temperature as well as the friction caused by running of train. All materials expand when heated and contract when cooled. The extent of expansion and contraction is quite low to be noticed by people or make much difference in most situations. However, since each section of the rail is very long, the expansion due to heating is significant, and unless space is provided for expansion of rails, the rails will bend to accommodate the increased length. This will make the railway unfit for running of trains.
Answer: the tracks will buckle under the force.
Explanation: Heat-related expansion places a lot of stress on the ties, ballasts, and rail anchors that keep the tracks fixed to the ground.

explain how you can recognize the sound of a flute
The sound of a flute is poetic, light, mellow, and soft. Flute is a woodwind musical instrument produces the mild sound.
How flute produces sound?Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as solid, liquid ang gases. When an object vibrates, it causes a movement in surrounding air molecules. The molecules collide with the molecules close to them, causing them to vibrating as well.
The sound from flute comes due to the vibrating columns of air inside it. In a flute, the air gets vibrated and the resonator amplifies the vibration and gets modified into sound. When air is blown into the holes of flute, it creates the vibration in the air molecules inside the flute and hence, sound is produced.
The flute can produced continuous sound by the presence of number of holes in it. The flute sounds may be high pitch or soft tone depends on the position of upper and lower lips on flute.The sounds of flute are rich, gentle and gracefull.

5] Set goals effectively
Goals are the basis of an effective performance management process. There are two key elements to consider when developing goals. First, are goals written clearly and objectively? Second, are they directly contributing to the achievement of business strategy?
Typically, the process begins with departmental managers setting goals for their departments, based upon organization-wide goals, which support the general business strategy. Making departmental goals accessible to all managers ensures there is no overlap, reduces conflict, and allows members of different departments to see where they support each other and ensure they are not working at cross purposes. Each manager in turn shares the overall goals with his/her department and meets with employees to identify individual performance goals and plans.
When setting goals, key job expectations and responsibilities should act as the main guide and reference. Goals should be set that not only address what is expected, but also how it will be achieved. For example, the "what" covers quality or quantity expected, deadlines to be met, cost to deliver, etc. The "how" refers to the behavior demonstrated to achieve outcomes, for example, focus on customer service. In addition, some organizations choose to include competencies within performance expectations, to reinforce the link to business strategy, vision and mission.
An accepted framework to use to help write effective goals is SMART

when a tiny stream forms during rainfall carrying away some soil and plants and leaving a scar.
Answer: Streams and rivers are integral parts of the landscape that carry water and sediment from high elevations to downstream lakes, estuaries, and oceans. The land area draining to a stream or river is defined as its watershed. When rain falls in a watershed, it either runs off the land surface, infiltrates into the soil, or evaporates.
