The unit for power in electricity should be watt. The power show how many energy transferred during a time and the SI unit would be joule per second.  

The bill is charging for the amount of energy. The energy could be calculated by multiplying the power with time. In this case, the power in kilo watt will be multiplied by the duration in hour which make the kilowatt hour.

Anit [1.1K]

Answer:

No it is not a proper waste disposal method

Explanation:

A man travelling in a train and throwing an empty packet off food on the platform and not inside the waste basket provided is definitely not a proper waste disposal. the best waste disposal method he would have used was throwing the waste in a waste bin

waste water management is the process of managing waste water emanating from homes or industries and controlling the negative impact this waste water would have on the environment. and one way to do that  is the proper treatment of the water which entails removing contaminants from the waste water and converting the waste water into a useful effluent that can be used again ,

charle [14.2K]

Answer:

1. 39 J; 2. 3.9 % usable; 3. 96.1 % unusable

Step-by-step explanation:

1. Available energy

Energy consumed              = 1000 J

Less waste         = - 177 J

Less respiration = <u>-784 J </u>

Total energy lost                = <u>-961 J </u>

Available energy                =   39 J

2. Percent of total energy usable

The chipmunk could use only 39 J of the original 1000 J.

% of energy usable = 39 J/1000 J × 100 % = 3.9 %

3. Percent of energy unusable

The chipmunk lost 961 J of the original 1000 J.

% of energy unusable = 961 J/1000 J × 100 % = 96.1 %
