What is the orbital period of a comet nucleus at the inner edge of the Oort Cloud (10,000 AU)? What is its orbital velocity? Assume a circular orbit. (Hint: Use Kepler's third law . P% aAU.) (N otes: The circumference of a circle is 2m 1 AU = 1.5 × 108 km 1 day = 86,400 seconds.)

Oa. 1 million years; 300 m/s.
b. 32 million years; 400 km/s
c, 32 million years; 9 m/s. O
d. 1 million years; 110 m/s.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

answer; how far out of place which the object finished relative to the starting location;

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
