A child has a toy balloon with a volume of 6.5 liters. The temperature of the balloon when it was filled was 2850 K and the pressure was 5.0 Pa. If the child were to let go of the balloon and it rose into the sky where the pressure is 3.5 Pa and the temperature is 2250 K, what would the new volume of the balloon be?

Then the answer would be d then

Indoraptor for sure

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
