Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the
gregori [183]

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

BIG POINTS To whoever answers this 50 POINTS ok Describe how energy is produced from power of water. In your answer, include the
ioda

Hydropower can be harnessed from flowing and falling water. Water stored behind dams and at a height has a lot of potential energy which is converted into mechanical and electrical energy.This water is released gradually and is made to fall under the force of gravity and drive hydraulic turbines and electri­cal generators. Hydropower is also another indirect form of using solar energy. Hydropower has great potential as a supplier of electricity but environmental constraints limit such a development as the generation of electricity by hydro­electric power plants result in pollution and massive ecological disruptions such as land flooding, siltation, eutrophication and adverse effects on flora and fauna. Smaller dams and reservoirs cause less damage but cannot exploit the full potential of this energy resource. Planning environmental impact assessment and construction of a hydroelec­tric power plant takes many years and the high initial capital investments are also limiting factors in the development of hydropower. The development cost of hydroelectric power plants can be reduced by developing low cost turbines and generators, involving public participation in the development and opera­tion of the project and using efficient environmental friendly technologies.
