is 1.99 times 10 30 kg and it's distance from earth is 1.50 times 10 11 m. What is the oeriod of the body in years?What is the speed of the body?Calculate the force of gravitational attraction between the sun and the body if it's mass is 5.00 times 10 10 kg.

F=GM1M2/R^2 for gravity
a^3=P^2 for period
This is what we used to call a "plug and crank" problem. You just plug the values into the formula and crank out the answer on a calculator.
use "a" as the radius or semimajor axis
To get speed, determine the distance the planet travels in its orbit (you remember how to calculate a circumfrence don't you?) and divide by the time it takes to make that orbit.

round 8 minutes. i do not understand the precise figure, yet our orbital speed is about 60,000 MPH, and Earth is about 8,000 miles in diameter, so it extremely works out to at least something like 8 minutes to flow 8,000 miles.

Hi. High school physics class, eh? You have the formula, just plug in the values.
