First, convert watts to kilowatts.
500w/1000= .5 kW per hour
.5*4 hours= 2kwh*365 days= 730 kWh
The answer is 730 kwh per year
Answer:
d. All of the above
Explanation:
A scale can be defined as an ordered numerical or alphabetical sequence that is typically used for taking measurements such as size, weight, height, length, etc. Also, a scale is used in the field of science to assign magnitude to physical activities and natural phenomenons such as an earthquake using the Richter scale.
In Science, there are four (4) main scales of measurement and these includes;
1. Interval scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.
2. Ratio scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.
3. Ordinal scale: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.
4. Nominal scale: it is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.
<em>Hence, scales can represent;</em>
<em>a. A range of information. </em>
<em>b. A range of resources. </em>
<em>c. Proportional measurement. </em>
Answer:
A)
Explanation:
b and e kills organisms, so it doesn't evolve the diseases. genetic modification causes the plants to be resistant, and doesnt target diseases, so the disease isnt evolved. only antibiotics make diseases evolve, overuse of it causes the disease to develop resistance if it isnt completely killed off.
