Backfilling is the right one
Answer:
Borders are imaginary lines that divide a nation, state, province or city from others. These dividing lines can be taken from geographic features, such as rivers, seas, lakes, mountains, etc .; or in geometric form, using lines as meridians and parallels; or for ethnic reasons, dividing populations based on languages, ethnic origin, etc.
Examples of each of these types of border are:
-Natural border between Argentina and Chile along the Andes Mountains, taking as the dividing line the highest point of the same.
-Geometric border between America and Canada on the west coast, taking the line of parallel 49 as division.
-Ethnic border between Pakistan and India, dividing both nations according to concepts of Islamic or Hindu religious affiliation.
Answer:
V ≈ 4577.204 cm^3
Explanation:
Use the volume formula V=4/3πr^3 to find the volume. Since you need the radius but are given the diameter, divide it by 2 to get half.
21.4/2 = 10.7
Now plug that into the formula and solve:
V=4/3πr^3
V=4/3π(10.7)^3
V= 4/3π(1,092.7272)
V= 4/3 * 3432.903
V= 4 * 3432.903/3
V = 13731.614/ 3
V ≈ 4577.204 cm^3 or whatever unit is stated.
Answer
• Driving a more fuel-efficient car to eliminate “gas guzzling”
• Reducing heating needs
• Reducing lighting needs
Explanation
The three best strategies employed worldwide for conserving non-renewable energy resources are Reduce, Reuse and Recycle( 3R’s). Energy users are encouraged to increase reliance on renewable energies such as solar, wind and geothermal to aid in conserving the scarce fossil fuel that remain.
Walking and biking can be used as a strategy to cut down gas guzzling and manage the limited nonrenewable oil resources. One popular way of heating homes is oil heating. However, the conserve the oil, home owners are supposed to put up storm windows and insulate homes including caulking cracks around doors and windows to reduce heating costs. When using natural gas, users can reduce energy wasting by keeping the thermostat at 70 degrees and shutting off heat when not in use.
Power is a function of voltage times the volume of electrons (current). Power is the ability to do work and is measured in Watts. The higher the voltage the more power you have with the same current.
