Thanks.

Those rankings are for grad school. Is there a big difference between their programs?

I'm a junior in high school and looking around for what colleges I want to apply to. In college I want to go into a physics major and I was hoping that someone could tell me which schools had the best physics programs. Thank you.

the data is correct, the point (0,1) does not lie on the circle the highest point of the circle is (0,0)

Homework Statement You have a circle with the equation x^{2} + (y + 1)^{2} = 1. You can draw to two tangent lines to that circle that intersect the point (0,1) What are the equations of these lines? And you can't use any calculus, derivatives and the like. Homework Equations y=mx+b...

Homework Statement If a cylinder rolls down a 3.04 meter ramp with a 30 degree incline without slipping, how fast will the rotational and translational speeds be when the cylinder reaches the bottom of the ramp? Homework Equations mgh = K_rotational + K_translational K_rotational =...

Thank you for your help.

Homework Statement A ballistic pendulum is a device used to measure the velocity of a projectile. The projectile is shot horizontally into and becomes embedded in the bob of a pendulum as illustrated below. The pendulum swings upward to some height h, which is measured. The mass of the bullet...

Thank you, that will make writing equations a lot easier.

Thank you, the problem I was having was that I was solving for the wrong radius. Also what program do you use to type up the equations?

I got that from cos41 = 6730/x which is equal to cos41x = 6730 which is then equal to x=6730/cos41.

I tried doing it as a right triangle which gave me the equation x(the radius at 41 degrees)= 6370/cos(41 degrees). The problem with that is that I get the speed of it to be 2.21 * 10^3km/hr, which is faster than at the equator. Which I believe is not possible because the equator should be the...

Homework Statement The Earth's radius is 6370 km, if you are sitting in a classroom on the equator how quickly would you be traveling? If you were in NY which has a latitude of 41 degrees N, how quickly would you be traveling? Homework Equations 2(pi)r=circumference The Attempt at...
