Answers

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.

One specific concern is the possibility for GMOs to negatively affect human health. This could result from differences in nutritional content, allergic response, or undesired side effects such as toxicity, organ damage, or gene transfer. Research indicates that GM crop technology can result in a net increase in herbicide use and can foster the growth of herbicide resistant weeds. In addition, there is concern that the use of GM crops may negatively impact the agriculture ecosystem.

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

Can somebody help me!!!

Answers

Answer:

8hours 16hours and 24 hours

Explanation:

this is because they 24÷3=8 so the time between the takings of the temperature are equal.

Divide 24 by 3 because 24 is the number of hours and 3 because it’s how many times you check it
24\3 = 8 or 8•3+24
So you would check the temperature every 8 hours
8 hours 16 hours 24 hours
