Helium fusion results in the production of

A) iron. B) nitrogen. C) carbon. D) oxygen. E) hydrogen.

Question 2

Using equations: The force due to gravity between two objects can be described using the equation .

How would one use Newton's second law to setup an equation one could use to find the gravitational acceleration experienced by an isolated astronaut 10,000 km from the Earth's center?

Answer to Question 1

C

Answer to Question 2

Should include some variation on the following:
(a) recognize that Newton's second law describes the relation between the net force acting on an object, the object's mass, and its acceleration (i.e., Force = mass acceleration).
(b) equate the two expressions (mass acceleration = G M1 M2 / d2).
(c) identify which object each variable relates to (Mass of astronaut acceleration of astronaut = G Mass of Earth Mass of astronaut / distance2)
(d) solve the equation for the acceleration of the astronaut (acceleration of astronaut = G Mass of Earth / distance2)
