Charon is a moon of Pluto that has a mass equal to 1/9 that of Pluto. The distance between the centre of Pluto and the centre of Charon is d. X is the point at which the resultant gravitational field due to Pluto and Charon is zero. What is the distance of X from the centre of Pluto?

The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. in part iii, you will be investigating the questionable baseball. use the drop-down menus to complete the sentences and identify the independent and dependent variables. in part iii, the independent variable, the one that is intentionally manipulated, is . in part iii, the dependent variable, the one that you measure the response in, is

The speed of light can be used to measure the

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
