Answer:

32 bottles

Explanation:

If we sketch a free body diagram for the child, we observe his weight alongside the buoyant force

W-B=0

They have to equalize for equilibrium to be maintained allowing him to float; this buoyant force matches the weight of the water displaced

W=B=Ww

Mg=mg

32 kg=mass of water displaced

given the water density of 1 kilogram per liter (kg/L), this indicates that a displacement of 32 Liters of water occurs. Thus, since each bottle contains 1 liter, the child would require 32 bottles

The flight of a kicked football follows the quadratic function f(x)=−0.02x2+2.2x+2, where f(x) is the vertical distance in feet
Keith_Richards [2907]
The ball covers a horizontal distance of 0.902 meters. The trajectory of a kicked football adheres to a quadratic equation expressed as: f(x), where f(x) indicates the vertical distance in feet, and x signifies how far the ball travels horizontally. To compute the distance the ball will advance before striking the ground, we set the condition f(x) = 0. Upon solving this quadratic equation, we find that the horizontal distance traveled by the ball is: x = -0.902 meters, leading us to conclude that it travels 0.902 meters across the field.

A kangaroo jumps to a vertical height of 2.8 m. How long was it in the air before returning to earth
serg [3228]
The kangaroo reaches a maximum vertical altitude of 2.8 m, which can be calculated using the formula 2.8 = 1/2 * 9.8 * t^2. Thus, applying the equation s = ut + 1/2at^2.

Yuliya22 [2968]
The time period for any moon of Jupiter is described by the formula above, which also allows us to calculate Jupiter's mass. For part a, T is 1.77 days, which is equal to 152928 seconds. Applying the formula, we can derive the values needed. For part B, T equals 3.55 days or 306720 seconds, and repeating this with the necessary formula allows us to find the mass of Jupiter. For part c, T is 7.16 days, equating to 618624 seconds. Once again, using the earlier formula, we find Jupiter's mass. Finally, for PART D, T is noted to be 16.7 days or 1442880 seconds, and we can find the mass of Jupiter using the provided formula.

kicyunya [2911]
Steam transforms into gas as it escapes into the atmosphere. Even if you manage to capture the steam as it ascends, it can revert to H2O when it cools down. Due to the evaporation process, the final volume of water will differ from the original amount.
