AI Thread Summary
To determine how much heat is needed to melt a 149 km long, 27.7 km wide, and 152 m thick iceberg, the mass of the ice is calculated using its density of 917 kg/m3 and its volume. The heat required for melting is then found by multiplying the mass by the heat of fusion for ice. The discussion also explores how long it would take to melt the iceberg if the annual energy consumption of the U.S. in 1994, 9.3 x 10^19 J, were applied to it each year. A participant notes that their initial calculation resulted in an incorrect value, emphasizing the need for a clear explanation of the calculation process. Accurate calculations are crucial for understanding the time frame for melting the iceberg.

Homework Statement


Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg is 149 km long, 27.7 km wide, and 152 m thick. (a) How much heat in joules would be required to melt this iceberg (assumed to be at 0 °C) into liquid water at 0 °C? The density of ice is 917 kg/m3. (b) The annual energy consumption by the United States in 1994 was 9.3 x 1019 J. If this energy were delivered to the iceberg every year, how many years would it take before the ice melted?


Homework Equations


heat required = mass of ice x heat of fusion for ice
mass of water is found from density and volume of ice
density of ice=mass of ice/volume of ice

a very large number not worth mentioning b/c its not right!

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
