You are looking to purchase a small piece of land in Hong Kong. The price is "only" $60,000 per square meter! The land title says the dimensions are 20 m ✕ 35 m. By how much would the total price change (in dollars) if you measured the parcel with a steel tape measure on a day when the temperature was 15°C above normal? (Include the sign of the value in your answer.)

think its the third option

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
