The ISS orbits the Earth at an altitude of 408 km.

recall: the Fc is equal to the net inward force on an object. consider the other force(s) acting on the ISS and write an equation. Air resistance is negligible.

Calc the acc

calc the orbital period

determine the speed that a rocket carrying supplies foe the ISS would have to achieve in order to orbit at the same altitude as the ISS.

The Hubble Spcae telesope orbits the Earth every 95 mins. Calc the altitude abover earths surface. 

1. For test tubes 1-5, list the entities initially present. Also, identify the SOA and SRA and predict the spontaneity of the reaction. 

test tube 1: Iron placed in distilled water

Test tube 2: Iron is placed in hydrochloric acid

Test tube 3: Iron is placed in magnesium

Test tube 4: Iron is placed in saltwater

Test tube 5: Iron is placed in de-aerated water

Test tube 6: Iron alone (controlled)

2. Using the SOA and SRA identified in Question 17, write the oxidation and reduction half-reactions and the net reaction for systems 2 and 4.

3. Explain why there was accelarated corrosion in test tube 3

4. Explain why the nails did not corrode in test tubes 4 and 5.

Do the four chromatids on a tetrad in meiosis 1 have different alleles?

if you were to jumo on a bathroom scale, explain how the scale reading would change before it settles to read your actual weight. Use newtons second law to justify what happens. 

i need help with this question please I'm really confused i need it by tomorrow. I'm desperate.

what is the radius of the earth orbit around the sun if it takes 365.25 days to complete one full orbit?(mass or sun 1.99x10^30 and ,mass of earth 5.97 x 10^24kg.

what is FC equal to?

replace FC with a formula and replace fg with newtons equation for gravity ?

solve for r

can you please show me the procedure so i can do it on my own thank you 

how to write a position paper

I need help with this question please I don't understand, I need it by tomorrow please I'm desperate.

find the these

..... how do I find the net force with on the 1000kg satellite, if the distance from the center earth to the moon is 384 00km, and the mass of the moon is 7.36 × 10^22 kg when the satellite is halfway between them

... how do i find the acceleration of gravity  (grevitational field strength) happening on a Russian Space Monkey orbiting the Earth 250km above the surface of the Earth.

also, can someone tell me how to find the tension? ex.having 10 mass (uk=0.55) and 3.5m/s^2

please show the procedure so I can do it on my own once again. thanks a lot
