a very large tank, closed from above and not open to the atmosphere, is partially filled with water. the pressure at the top surface of the water is kept at three times atmospheric pressure by constantly injecting pressurized air from above. water emerges from the tank through a circular nozzle that is located close to the base of the tank and is open to the atmosphere. at the instant when the water stands high above the nozzle, what is the water flow rate from the nozzle? the cross-sectional area of the nozzle is . g

Answers

Answer 1

Answer:

Answer:

the water flow rate is higher than the atmospheric pressure

ICl has a higher boiling point than Br2. What is the best explanation for this?

Answers

Iodine Monochloride (ICI) is an interhalogen or compound. ICI has an intermolecular attraction which makes it more difficult to boil compare to Bromine (Br2). Brorime is among the halogens along with fluorine, chlorine, iodine and astatine. Bromine is a nonpolar substance while ICI is a polar compound.

A person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.A) What is her average speed over the entire trip?B) What is her average velocity over the entire trip?

Answers

Answer:

A.) 3.975 m/s

B.) 0.925 m/s

Explanation:

Given that a person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.

A) What is her average speed over the entire trip?

The average speed = (4.90 + 3.05)/2

Average speed = 7.95/2

Average speed = 3.975 m/s

B) What is her average velocity over the entire trip?

Since velocity is a vector quantity, that is, we consider both the magnitude and direction

Average velocity = ( 4.90 - 3.05)/2

Average velocity = 1.85/2

Average velocity = 0.925 m/s

If a ball is rolling with 5 pounds of force, how much force will be needed to stop the ball from rolling and why? A It would take 25 pounds of force to stop the ball from rolling becae it takes five times as much force to stop as object. B It would take 2.5 pounds of force to stop the ball from rolling becae it takes half of the amount of force to stop an object. C It would take 10 pounds of force to stop the ball from rolling becae it takes double the amount of force to stop an object. D It would take 5 pounds of force to stop the ball from rolling becae the same amount of force mt be ed to stop the object.

The principal limitation of wind power is unpredictability. Please select the best answer from the choices provideda. True
b. False

Answers

The correct answer is A: True. Although the ability to forecast weather has increased over the years, the ability to predict when and how much wind will occur at any given time and place is difficult. Weather conditions are subject to constant change and while some areas are known to have more wind than others, there is no guarantee about how much wind there will be as weather patterns vary in consistency.
