Pls help ASAP on both PLS I BEG 8.9.A boy leaning out of his top-floor window one day accidentally knocks a flowerpotfrom the windowsill and he hears the sound of the crash 2.5 s later. The boy canuse this time to calculate the height of his window. What is the approximateheight of the windowsill above the ground?A. 20 mIn the last question the boy realizes that in his calculations for height (h) he hasneglected the effect of air resistance and also the time it took for the sound totravel to his ear. A better value for h could be obtained by allowing for thefollowing:ABCDB. 25mC. 30 mAllowing for the speed of soundTime should be shorter than measured, trueh would be smallerTime should be longer than measured, trueh would be smallerTime should be shorter than measured, trueh would be largerTime should be longer than measured, trueh would be largerD. 40 mAllowing for air resistanceTime should be longer than measured,true h would be largerTime should be shorter than measured,true h would be largerTime should be longer than measured,true h would be largerTime should be shorter than measured,true h would be smaller

To calculate the height of the windowsill above the ground, we can use the following equation:h =…
