B.
One wind turbine is a worse energy source because the amount of carbon dioxide released during manufacturing is more than that of 40,000 solar panels.
C.
There is no difference between one wind turbine and 40,000 solar panels in terms of the amount of carbon dioxide released.
D.
40,000 solar panels is better energy source than a wind turbine because of the amount of carbon dioxide released during use.
One wind turbine is a better energy source because the amount of carbon dioxide released during manufacturing is less that of 40,000 solar panels. That is option A.
What is renewable energy sources?Renewable energy sources are those energy sources that can be replaced or replenished naturally. Example of renewable energy sources are sun and wind.
The solar energy is gotten from the sun while wind energy is gotten from the wind.
According to research, one wind turbine produces 4.64 grams of CO2/1kWh while the solar panel produces 70 grams of CO2/1kWh.
Therefore, one wind turbine is a better energy source because the amount of carbon dioxide released during manufacturing is less that of 40,000 solar panels.

The sides of a triangle measure 18 inches, 25 inches, and 36 inches. To the nearest degree, what is the measure of the largest angle? A 113° C 157° B 147° D 159°
Answer:
A. 113°
Explanation:
opposite of the largest side is the largest angle
a=18 b=25 c=36
law of cosines
largest angle= arccos((a^2+b^2-c^2)/2ab))
largest angle= arccos((18^2+25^2-36^2)/2*18*25))
largest angle= arccos(-347/900)
largest angle= arccos(-0.38555555555)
largest angle= 1.96660618 rad

This igneous rock contains angular pieces of gray volcanic rocks in a matrix of powdery volcanic ash and smaller rock fragments. What type of eruption probably formed this rock
The igneous rock that was described, which contains angular bits of gray volcanic rocks amidst a matrix of powdery volcanic ash and smaller rock fragments, was probably created by a volcanic eruption known as a "pyroclastic eruption" or "pyroclastic flow."
A mixture of broken rock, volcanic ash, and hot gases is released into the atmosphere during pyroclastic eruptions, which are extremely explosive volcanic events. When this mixture, also known as pyroclastic material or tephra, flows rapidly down a volcano's flanks, it significantly damages the region nearby.
The gray volcanic rock's angular shards are probably portions of pre-existing volcanic material that were broken and ejected during the eruption.
The explosive eruption also produced powdered volcanic ash and smaller rock pieces in the matrix, which stand in for the finer-grained particles that settled and collected during and after the eruption.
