AI Thread Summary
The Sun radiates energy at a rate of 3.9 x 10^24 Watts, which translates to 3.9 x 10^24 Joules per second. To determine the mass loss due to this radiation, the equation E = Δmc^2 is applicable, where E represents energy and c is the speed of light. By evaluating the energy loss over a time interval of one second, the mass loss can be calculated. The discussion highlights the need for clarity on how to apply the equations to find the mass loss rate. Understanding these principles is crucial for solving the problem effectively.

Homework Statement


The Sun radiates away energy at the rate of 3.9*10^24 Watts. At what rate it it losing mass due to this radiation?


Homework Equations


E = Δmc^2
E = mc^2 - m0c^2

Where m0 rep. rest mass.


The Attempt at a Solution


For this one, I am unsure as to how I would go about with solving it.
I know that a Watt can equal 1 Joule / second...

So then the Sun must radiate energy at 3.9*1024 Joule / second.

It will help if you consider a useful time interval, say 1 second, for your evaluation.
 

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

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 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...
