40*50=2,000 Hours so 2,000*10=20,000 and 20% of 20,000 is 4,000 so $4000 is how much Anna pays in taxes.
According to the, Kinetic Molecular theory, temperature is directly proportional to average Kinetic energy of gas particle
Explanation:
At the level of molecule kinetic energy model helps to understand the gaseous physical properties. The kinetic energy model is based on several concepts.
In the constant random motion gases are made of molecules or atoms.
The particles of gases are are constantly colliding with each other.
The particles of gas are small and the complete volume taken by gaseous molecules are negligible in comparison to complete volume of container.
Between the gas particle their is no repulsion or attraction.
Gas particles average kinetic energy is proportional to the fixed temperature of the gas, and all gas at the equivalent temperature have the equivalent average kinetic energy.
The correct answer is D. They mapped trails and helped build forts
Explanation
Mountain men are a group of people who lived in the western mountains of the United States. These mountains were characterized by being difficult to access, so there were no roads in this area, and it did not have many human settlements. Once the idea of building and connecting the entire country was planted, the help of men who inhabited this area was needed to trace the roads and build them because they knew how to move and work on that terrain due to their extensive experience in that terrain. Therefore, the correct answer is D. They mapped trails and helped build forts
Answer:
airborne psychological operations
Explanation:
Flying the EC-130 Commando Solo, the 193rd Special Operations Squadron conducts information operations, psychological operations and civil affairs broadcasts in AM, FM, HF, TV and military communications bands.
Since WW2 until today, the 193rd Special Operations Wing continues this tradition of maintaining the only airborne psychological operations broadcasting platform for the entire U.S. military.
