AI Thread Summary
To determine the time required to boil away 1.1 kg of water using a 1500 W stove burner, the latent heat of water must be considered. The relevant equation for heat transfer is q = mct, where 'm' is mass, 'c' is specific heat, and 't' is time. After reaching the boiling point, the energy needed to convert the water to steam can be calculated using the latent heat of vaporization. The relationship between power, energy, and time will then provide the final time needed for the process. This approach ensures an accurate calculation of the boiling time.

Homework Statement


A stove burner supplies heat to a pan at the rate of 1500 W. How
long will it take to boil away 1.1 kg of water, once the water
reaches its boiling point?


Homework Equations


q = mct


The Attempt at a Solution



heat transfer = 1500 W, m = 1.1 KG Tf = 100

Look up latent "heat of water". That will allow you to calculate the amount of energy needed to turn 1.1kg of water at 100C into steam at 100C.

Then remember the equation that relates Power, Energy and Time.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged 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...
