Explanation:
I seen this one before and know the answer since there's 4 options
Answer:
Force, 
Explanation:
Given that,
A potential energy function for a system in which a two-dimensional force acts is of the form of :

We need to find the force that acts at the point (x, y). The force in 2 dimensional with components is given by :

So, the force acting at the point (x,y) is
. Hence, this is the required solution.
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
Answer:
Mass as a Measure of the Amount of Inertia
All objects resist changes in their state of motion. All objects have this tendency - they have inertia.
