No, the building's size in comparison to the earth would have no change or change so increadibly miniscule, like if you were told to spin slowly and an and was placed on top of your head

(a)
The formula is:
∑ F = Weight + T = mass * acceleration
as the elevator and lamp are moving downward, I choose downward forces to be
positive.
Weight is pulling down = +(9.8 * mass)
Tension is pulling up, so T = -63
Acceleration is upward = -1.7 m/s^2
(9.8 * mass) + -63 = mass * -1.7
Add +63 to both sides
Add (mass * 1.7) to both sides
(9.8 * mass) + (mass * 1.7) = 63
11.5 * mass = 63
mass = 63 / 11.5
Mass = 5.48 kg
(b)
Since the elevator and lamp are going upward, I choose upward forces to be
positive.
Weight is pulling down = -(9.8 * 5.48) = -53.70
Acceleration is upward, so acceleration = +1.7
-53.70 + T = 5.48 * 1.7
T = 53.70 + 9.316 = approx 63 N
The Tension is still the same - 63 N since the same mass, 5.48 kg, is being accelerated
upward at the same rate of 1.7 m/s^2
Answer:
1. Since its in equilibrium:
Qcopper = Qwater
(mCu*cCu*deltaT) =(mwater*cwater*deltaT)
((8.5)(386)(x-750)) = (5.4)*(4186)*(x-293)
(3281x - 2460750) = 22604.4x - 6623089
3281x + 2460750 = 22604.4x - 6623089
9083839.2 = 26185.4x
x = 346.904K = Final Temperature
2. Since equilibrium and change in phase:
mcu*cCU*deltaT = mevap*Latent Heat + mwater*cwater*deltaT
Final Temperature is 373K because that is when liquid water becomes gas water
(8.5*386*(373-1350) = mevap*(2.26*10^6) + (5.4*4186*(373-293))
3205537 = mevap*(2.26*10^6) + 1808352
1397185 = mevap*(2.26*10^6)
mevap = .61822 kg
This is the amount evaporated we need the amount remaining so subtract from the initial amount of water:
5.4 - .61822 = 4.782 kg remaining
