From the given problem, a limit on the depression of a building is placed at 20 centimeters. To solve how many floors can be safely added, a quantity of how many cm will a building sink for each floor that is added is needed. Unfortunately, it is not found anywhere in the problem. However, we can provide a formula to solve for the depression. This is as follows:
Building depression < 20 cm
Building depression = (cm depression per floor) * (no. of floors)
<span>Energy is neither lost nor gained as it transforms from chemical, to heat, to mechanical energy.</span>
force is mass * acceleration
so 2kg * 2m/s^2 = 4 N
Answer:
Do = density of obect Dw = density of water
Weight of object = V g Do
Weight of water = V g Dw
F = m a = V Do a = V g Do - V g Dw
Acceleration of object = mass * force on object
Do (g - a) = Dw g
Do = Dw ( 1 / (1 - a / g) = 1000 * 1 / (1 - 3.75 / 9.80) kg/m^3
Do = 1441 kg / m^3
If no acceleration then density of object = density of water
