What is ∑f2x, the sum of the x components of the forces acting on block 2? take forces acting up the incline to be positive. express your answer in terms of some or all of the variables tension t, m2, the magnitude of the acceleration of gravity g, and θ.

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
