What is the Centripetal Acceleration of Earth's Orbit Around the Sun?

AI Thread Summary
To calculate the centripetal acceleration of Earth in its orbit around the Sun, the relevant formula is Fc = mv^2/R, with the radius given as 1.496x10^11 meters. The mass of Earth is not provided, leading to challenges in the calculation. A hint suggests finding a relationship between centripetal acceleration and the period of rotation, using the formula Acc = radius x omega^2, where omega is derived from the orbital period. The user attempts to calculate omega using a year in seconds but reports incorrect results. Providing detailed calculations may help identify errors in the approach.

HINT: Can you find a relationship between the centripetal acceleration and the period of rotation?
 
okay thanks for the hint but i didnt really get the answer. taking the formula

Acc = radius x omega^2
omega = 2pie (1orbit) / time

i took time to be 365.25 x 24 x 60 x 60 to get s.

My results were wrong :(

Perhaps if you showed us your calculations, we could point out where you're going wrong.
 

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'

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...
