Draw a table of values for Dependent variable Y and independent variable X, using the equation Y = 2X + 3, for values of X ranging from -2 to +3. Using the equation of a straight line, Y = mx + c, ​

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?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
