a bird that was perched on a tree branch began flying south. the bird flew 1,800 miles south before landing on another tree branch 40 hours later. what was the average velocity of the bird during its flight?

72,000 mph south

72,000 mph north

45 mph south

45 mph north

The average velocity of the bird during its flight is 45 mph due south.

Explanation:

Given that,

The bird flew 1800 miles south before landing on another tree branch 40 hours later. We need to find the average velocity of the bird during its flight. We know that the velocity of the bird is given by the formula as :

As the bird is moving due southward direction, then the average velocity of the bird during its flight is 45 mph due south. Hence, this is the required solution.

The partial pressure of argon can be calculated simply by dividing the total pressure by 3. This gives an answer equivalent to 10893.33 Pa. The clue behind this is the statement "all gases have the same partial pressure". This follows Dalton's Law of Partial Pressures which states that the total pressure is equal to the sum of the individual partial pressures.
