Calculate the acceleration of a car (in km/h. s)
that can go from rest to 100 km/h in 10s

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).

Examine the drawing of a molecule. each ring represents an atom of nitrogen (n). what’s the chemical formula of this substance?
