Alex performs a lab experiment with a radio-controlled cart. He measures the speed of the cart as it accelerates along a straight track. The following table shows his data. Based on evidence in the table, what is the average acceleration of the cart after 3 s? k (1 Point) A. 2.0 m/s^2 B. 1 m/s^2 C. 1.5 m/s D. 3 m/s​

The best description is: . nobody has any idea what q is.

All are great precautions but you can still lift lighter and different muscles in between hard workdays. this keeps other muscles not usually used in shape.

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
