D hurricanes makes the most sense because lightning isn't and blizzards have nothing to do with ocean waters and tornadoes only occur inland.
Answer:
virus
Explanation:
Virus is the correct answer
Wind power:
Advantages:
-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.
-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.
-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.
Disadvantages:
-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.
-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.
-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.
Answer:
8 miles
Explanation:
Velocity is speed+direction (the speed of something in a given direction). We know that running on a track, one is moving forwards, which is why the velocity given as positive. Now we do some simple algebra. 120 minutes is equal to 2 hours. At a velocity of 4 miles an hour, for 2 hours, you multiply 4x2 and get 8, which is how far (in miles, units are important) the man has traveled once he comes to a stop.
