5. Moon gravity problem

This problem was given on a previous test...the problem is written exactly as seen on the actual exam: Moons gravity is (6.67 x 10 ^-11 N m^2/kg^2) (7.36 x 10^22 kg) ___________________________________________ (1.74 x 10^6m) ^2...
6. Moon gravity problem

(6.67 x 10 ^-11 N m^2/kg^2) (7.36 x 10^22 kg) ___________________________________________ (1.74 x 10^6m) ^2 simplify: 6.67 x 7.36 ___________ x 10^-11=22-6(2) x Nm^2/kg^2 * kg 1.74 ^2 ____________ _____________...
7. Difficulty on some distance problemsneed help

I think that posting answers along w/ the worked out problems helps a lot more in understanding it thoroughly....but I guess if those are the rules thats cool...Thanks to both of you I was able to understand the problems more and get the final answers.. :)
8. Difficulty on some distance problemsneed help

You were given all the information called for by this equation except a, which you are supposed to solve for. I dont know what xf and xi are used for, which variables? You've got the right equation. The tension is equal to Fc. But why are you dividing by 3.14? As the equation says, you...
9. Time required to go to Mars

I got 71181818.18 = 71 seconds as my answer. THX :)
10. Time required to go to Mars

11,000 m/s __________ 21,751,740 = 5.05 x 10^ -4 I got my numerator figure by converting 78.3 x 10 ^6 km and got 21,751,740 m/s
11. Difficulty on some distance problemsneed help

Recently took a test and got one of the lowest scores I've ever gotten....theres no tutor avaliable and the prof isnt avaliable either....I'm trying to figure out the correct answers and how and which equations to use for each problem. I always have difficulty interpreting the questions and...
12. Time required to go to Mars

A rocket moves through space at 11,000 m/s. At this rate, how much time will be required to go to mars (78.3 x 10^6 km)? i used t= d/v and got 5.05 x 10^ -4 I'm not sure what i'm doing wrong. I cant get the correct answer

suggestions on any good Niels Bohr sites.... Taking a summer physical science class..and my presentation is on Niels Bohr....I wanted to know if there were any good sites anyone can point me to. THX :)
14. Question when doing a simple investigative experiment .

question when doing a simple investigative experiment..... should such variables as mass be similar to each other? what would be the advatages? disadvantages? I said that the masses really shouldnt be similar...you're trying to get a data spread and you want your masses to not be similar...
15. Light question .difficulty finding answer

Light question.....difficulty finding answer.... My prof. just gave us about 6 questions on the last chapter of the summer semester, which is on light...he said we could try the question but if we couldnt get it right it was okay....I tried it anyways and I cannot get it.... At what range...
