What causes satellites to remain in orbit above Earth? A) Satellites achieve a balance between gravity and their velocity that keeps them in orbit.

B) Satellites reach their escape velocity with the help of scientists and engineers.

C) Satellites have a circular or elliptical orbit.

D) Gravity pulls satellites sideways around Earth's curved surface.

After a car's engine has been running for a while, if you stand near the car's engine you can often feel heat coming from the engine as a result of a. radiation b. convection c. conduction

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
