Hannah has information about an object in circular orbit around earth.

mearth = 6.0 × 1024 kg

g = 6.67 × 10–11 startfraction m superscript 3 baseline over kilograms times s superscript 2 baseline endfraction.

what additional information does hannah need in order to calculate the tangential speed of the orbiting object?

the mass of the orbiting object
the distance of the orbiting object to earth
the orbital period of earth
the radius of earth

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

not: both offer magnification to the atomic level.
