I get it now. My Physics teacher explained it to me after school. Thank you!

No I didn't. So it would double as well?

It would increase?

Homework Statement Suppose the mass of the Earth were doubled , but it kept the same density and spherical shape. How would the weight of objects at the Earh's surface change? Homework Equations Fg=Gm1m2/r^2 The Attempt at a Solution g=G2m/r^2 g=19.59817612 g/g(on Earth - 9.8)...

Thank you so much!

How do you get 63.347 N for the force that the hinge exerts? Sorry for asking all these questions, this question is just really confusing me though.

I know but I don't know why the answer is 11 degrees NW, that's where I am confused.

Homework Statement A rod of negligible mass is supported by a hinge at the wall by a horizontal wire fastened at a 30 degree angle one-third of the way along the rod. A weight of 12 N hangs from the left end of the rod. a) Find the tension (T) in the horizontal wire. (T = 62.2 N) b) Find...
