To calculate the volume of a cylindrical water tank, you can use the formula for the volume of a cylinder:
Volume = π * r^2 * h
Where:
- π (pi) is approximately 3.14159
- r is the radius of the cylinder
- h is the height of the cylinder
In this case, the radius (r) is 3 yards, and the height (h) is 7.5 yards. Plug these values into the formula:
Volume = π * (3 yards)^2 * 7.5 yards
Volume ≈ 3.14159 * (9 square yards) * 7.5 yards
Now, calculate the volume:
Volume ≈ 3.14159 * 67.5 cubic yards
Volume ≈ 212.05325 cubic yards
So, the volume of the cylindrical water tank is approximately 212.05 cubic yards.
Track runners start at different positions on the track to ensure that each runner covers the same distance during the race.
In track events, particularly in sprints, the distance to be covered is the same for all competitors (e.g., 100 meters, 200 meters, 400 meters, etc.).
To compensate for the curved shape of the track, which can create unequal distances for runners in outer lanes compared to those in inner lanes, runners start from staggered positions. The lanes closer to the inner part of the track have a smaller radius and, therefore, a shorter distance to cover in each lap compared to the outer lanes.
By starting at staggered positions, each runner has an equal distance to run during the race. This helps ensure fairness in the competition and eliminates the advantage that could be gained by running in a specific lane.
The starting positions are determined based on the lane number, with the innermost lane (lane 1) starting at the shortest distance from the finish line and the outermost lane starting at a greaterdistance to compensate for the curvature of the track. This ensures that all runners have an equal opportunity to perform at their best regardless of the lane they are assigned to.
Hence, Track runners start at different positions on the track to ensure that each runner covers the same distance during the race.

Answer:
when a thin transport sheet is placed in front of the double
slit no physical quantities affecting the fringe withers changed therefore the fringe width remains the same
Answer:
Boiling is the "rapid vaporization of liquid" when the liquid is heated at the point where the pressure of the vapor is equal to the pressure exerted by the atmosphere in the liquid.
So during the boiling, the vaporization of the water is also occurring but is a little bit more complex.
Some questions that you may ask your friend to differentiate those two phenomena are:
Which one is used to cook things like pasta? (boiling)
in which process, a liquid is transformed into a gas? (evaporation)
Which one includes the other? (boiling)
Evaporation and boiling are both phases changes, but they differ in the specifics of how and when they happen. These differences involve the temperature and location within the liquid where they occur, as well as the speed of the process.
To differentiate between evaporation and boiling, you could ask your friend these questions:
By asking these questions, your friend will be able to identify the key differences that separate evaporation from boiling.
